Alcohol and fitness to drive

🍺🚗0️⃣5️⃣Experienced driver: maximum 0.5 promille blood alcohol.

Picture a beer glass sliced perfectly in HALF: 0.5 = one half. The experienced driver may only go up to the halfway line, not a drop more.

🔰🍺0️⃣2️⃣Beginner driver (first 5 years): maximum 0.2 promille.

The 2 in 0.2 looks like a swan shaking its head NO: the beginner with the L-plate may have almost nothing. 2 tiny sips and it's already too much.

🔰🖐️🗓️🚗You are a beginner driver for the first 5 years after your first licence (7 years if you started under 18 on a moped).

Hold up your HAND: 5 fingers = 5 years on probation. For five years you wear the invisible green 'beginner' badge.

🔰0️⃣2️⃣🎓0️⃣5️⃣Mnemonic: Beginner = 0.2 (small), Experienced = 0.5 (bigger). More experience, a bit more margin.

Think of stairs: the beginner stands on step 2, the experienced driver climbed 3 steps higher to step 5. Experience climbs from 2 to 5.

🚫🍺👮💸Over the limit: a fine, and with high levels a driving ban or invalidated licence. The safest rule: the designated driver drinks nothing.

Picture the sober driver with a big 0 on his shirt: zero glasses, zero worries. Every drop is a euro out of your pocket.

Novice drivers (licence held less than 5 years, or less than 7 years if your first licence was an AM or T licence obtained before you turned 18) may have a maximum of 0.2 per mille alcohol in their blood.

Think: '2 = too new'. The beginner is still 'almost zero' behind the wheel, so almost no drop: 0.2.

Experienced drivers (licence held 5 years or more) may have a maximum of 0.5 per mille alcohol in their blood.

5 years of experience pairs with 0.5 per mille: the two fives click together, experience and limit rise as one.

Even below the legal limit you may not drive if alcohol makes you unable to drive safely; the police can still take you off the road.

The limit is a ceiling, not a permission slip: wobbling under 0.5 still means getting in = getting pulled out by police.

Some medicines reduce your fitness to drive; check the yellow warning sticker or the leaflet and do not drive if it says driving ability is affected.

Yellow sticker = yellow traffic light: yellow on the box means stop driving, not carry on.

Never drive when tired; fatigue slows your reaction time and can cause a micro-sleep of a few seconds in which you lose control of the vehicle.

A 4-second micro-sleep at 100 km/h = over 100 metres driven blind: your car crosses a football pitch while you 'just' close your eyes.

For fatigue only real rest helps: stop, take a break and sleep if needed; coffee, loud music or an open window are only short, unreliable stopgaps.

Coffee doesn't patch sleep away: it's a plaster on fatigue, only sleep truly recharges the battery.

Traffic rules

🏙️5️⃣0️⃣Inside the built-up area the limit is 50 km/h.

Picture a giant swan (shaped like a 5) floating next to an empty plate (0) in a canal: 50 through town. The swan hisses at every speeder: 'Easy, this is the built-up area!'

🐄8️⃣0️⃣Outside the built-up area the limit is 80 km/h.

Outside town a fat cow with a figure-8 pattern (two round spots) stands by a round hay-bale zero: 80 past the meadows. 'Ate-y, eighty!' she moos.

🚗🔴1️⃣0️⃣0️⃣On the autoweg (red sign with white car) the limit is 100 km/h.

Autoweg = one car on a red sign, and one car drives a hundred: a 1 with two wheels behind it = 100. Remember: red car, round hundred.

🛣️☀️1️⃣0️⃣0️⃣🌙1️⃣3️⃣0️⃣On the motorway the limit is 130 km/h, but daytime 06:00-19:00 it is 100 km/h.

On the motorway the 130 sleeps in by day: while the sun shines (6-19h) you may only do 100, and only when the moon rises do you leap to 130. Sun = hundred, moon = more.

🏙️5️⃣🐄8️⃣🚗🔟🛣️1️⃣3️⃣Without signs the defaults are: built-up area 50, outside 80, autoweg 100, motorway 130 (100 by day).

Climb the staircase: town 5, cows 8, car 10, motorway 13 — stick a 0 on each and you get 50-80-100-130. Every step outward, the road widens and the number grows.

🚗💨🕐2️⃣Keep at least a 2-second gap to the car in front. When it passes a fixed point, count '21... 22' — if you reach the point sooner, you're too close.

Picture two fat crocodiles lying on the road between you and the car ahead: 'one-crocodile, two-crocodile'. If they get squashed, you were driving way too close!

🧠➕🛑🟰📏Total stopping distance = reaction distance (while you react) + braking distance (while you brake). Together they decide how far you still travel before standing still.

Think of a relay race: first your BRAIN runs with the baton (reaction distance), then the BRAKE takes over (braking distance). Two runners back-to-back = total stopping distance.

⏩2️⃣✖️4️⃣📏Braking distance grows with the SQUARE of speed: drive twice as fast and your braking distance becomes about FOUR times as long.

Double the speed, the braking distance goes SQUARE: 2 becomes 4! Picture a rubber band you pull twice as hard — it flies four times as far.

🌧️🛞🧼➡️📏On a wet road the braking distance is longer than on a dry road: less grip, so keep more distance and brake more gently.

Imagine braking on a bathroom floor full of soap: your tyres SLIDE right through and you skid much further. Wet = soap slide = longer braking distance.

🌫️❄️➕🕐🚗In poor visibility, rain, black ice or at high speed, increase your following distance: more than 2 seconds, because reacting and braking then cost extra metres.

Rule: the worse the weather, the more crocodiles you add. In rain drop a THIRD counting crocodile on the road: '21, 22, 23' — extra room saves your bumper.

🌫️🚗2️⃣0️⃣0️⃣Front fog light may only be ON when fog, snow or rain seriously reduces visibility; rule of thumb: under 200 metres (the law sets no distance).

FRONT = Far: you squint through a wall of fog, and only when you can't see two football fields ahead (2 x 100 m = 200 m) do you flick the front fog on. 'Front at two hundred!'

🌫️🔴5️⃣0️⃣Rear fog light may only be ON in fog or snowfall with visibility less than 50 metres.

REAR = Red and close: the blinding red rear fog is so harsh you may only switch it on when fog or snow cuts your visibility to under 50 metres (half a football field). 'Rear at fifty!'

🚗2️⃣0️⃣0️⃣🔴5️⃣0️⃣Remember the split: front fog when visibility is seriously reduced (rule of thumb 200 m), rear fog only under 50 m (legal limit).

Rhyme trick: 'Front sees Far (200), Rear stays near (50).' The big distance looks FORWARD; the small number lags BEHIND — like a small child trailing close behind you.

🌙💡🚗In the dark you drive with dipped headlights (dimlicht), not with parking lights only.

The moment the moon rises and it goes dark, flip the 'dip' switch: dipped headlights are your night glasses. Parking lights alone are like driving in pitch black wearing sunglasses — far too little light.

🏟️🏟️🌫️🔴200 m = two football fields (rule of thumb for front fog lights; the law sets no distance), 50 m = half a football field (legal limit for the rear fog light).

Picture it: a giant fog cloud first swallows two whole football fields (200 m) → front fog on. It thickens until even half a field vanishes (50 m) → now the red rear fog joins in.

Keeping right is the main rule: drive as far right as possible, including on multi-lane roads outside built-up areas. The left lane is only for overtaking; afterwards you merge back to the right.

Picture a library hallway: you walk on the right, use the middle only to pass someone, then slide right again. RIGHT = your home spot, LEFT = passing only.

You overtake on the left as a rule. Only overtake when you have enough sight and space to return safely without hindering the driver you passed.

Left = Lane over. If you can't see the END of your overtake, you stay behind — no clear finish, no start.

Overtaking on the right is only allowed in a traffic jam or slow-moving traffic: when lanes move at different speeds side by side, your right lane may move faster. Otherwise, passing on the right is forbidden.

'Jam = Right is fair game.' Only when traffic clogs and lanes crawl may the right move faster. Open road? Right-side passing stays taboo.

You may NOT overtake just before or on a pedestrian crossing, nor just before or on a railway crossing. Also not where sight is insufficient, such as at a bend or the crest of a hill.

The 'STRIPES-RAILS-BLIND' stop rule: on stripes (zebra), on rails (crossing) and in the blind (bend/hill), keep the wheel straight — no overtaking.

If a driver ahead wants to turn left and has already moved to the left, you pass that driver on the right. This is an exception where passing on the right is allowed.

'He goes left, you slip right.' The left-turner clears the left side, so you naturally squeeze past on the right — mirror images of each other.

When you are being overtaken, you must not speed up. Keep your speed (or slow down if needed) and stay as far right as possible so the overtaker can merge back safely.

Be a 'polite host': when someone wants past, you step aside (to the right) and don't hit the gas. Speeding up during an overtake is rude and forbidden.

Road signs

🔴⭕🚫Round sign with a red border = PROHIBITION (something is not allowed).

Red = your mother's stop light: round and red screams 'ROUNDLY forbidden!'. The red ring is a handcuff that snaps around your wrist the second you try something not allowed.

🔵⭕➡️Round sign, blue = MANDATORY (you MUST do this, e.g. compulsory direction).

Blue = the blue sky where an angel grabs your hand and says: 'you MUST go this way'. Round blue = an obedient order, no choice.

🔺❗⚠️Red TRIANGLE (point up) = WARNING of danger ahead.

A triangle pointing up is an exclamation mark without its dot: 'Watch out!'. Its three sharp corners prick your attention: danger is coming.

🟨🔶🛣️Yellow DIAMOND = PRIORITY ROAD; you have right of way.

The yellow diamond is your royal crown jewel: while it sparkles, you are the king of the road and everyone bows to you. Yellow = gold = priority.

🔻⬇️🅿️INVERTED triangle (point down) = GIVE WAY to traffic on the crossing road.

The point aims at the ground: it pushes your gas pedal down and says 'easy, let the others go first'. Point down = you rank down = give way.

🛑🐙✋OCTAGON (STOP sign) = come to a FULL stop, even if the road is clear, then proceed.

Eight corners = the eight arms of an octopus that grip your car until you are 100% still. An OCTagon like an OCTopus: freeze completely!

Special conditions

🌉❄️🥶In frost, bridges and viaducts freeze first: cold air flows under them too.

Picture a bridge that's cold from BELOW and ABOVE — so it puts on its ice-coat first. The road on the ground has the warm earth as a blanket; the bridge dangles in the air and shivers first.

🚗💦🏄Aquaplaning: at higher speed on a wet road the tyres lose grip and the car 'floats' on water. Reduce your speed.

The faster you go, the more your car becomes a SURFBOARD: the tyres can't push the water away and you surf on, unable to steer. Ease off the gas = the board sinks back into the sea and grips again.

🌫️🔦2️⃣0️⃣0️⃣In fog that seriously reduces visibility (rule of thumb < 200 m) you may use front fog lights; the rear fog light may ONLY be on when visibility < 50 m.

Count the zeros like football pitches: at 200 m the FRONT lamp may go on, but the fierce REAR lamp is so blinding you may only use it when fog nearly swallows you — 50 m. Front = far (200), Rear = right-in-your-face (50).

🌬️🌉🚚Cross-wind is strongest on open roads, bridges and at forest edges/viaducts; hold the wheel firmly and watch for overtaking trucks.

On the open road the wind is an invisible GIANT shoving your car — but behind a passing truck he vanishes for a second, then SMACKS you back the moment you clear it. Grip the wheel like a helmsman in a storm.

🌫️🚗🧱In fog: cut speed sharply, keep more distance and NEVER use main (high) beam — it reflects back like a white wall.

Switch on high beam in fog and you build a WHITE WALL right in front of your nose — the light bounces back and you see even less. Dipped beam = pierce the fog; high beam = crash into the wall.

In a tunnel you always switch on your dipped headlights, even during the day. Keep extra following distance: at least 2 seconds as a rule, and obey any minimum-distance signs or matrix signs shown in the tunnel.

Think: 'Tunnel = you go blind, so make yourself seen.' As it darkens at the entrance you click your dipped beams on like flicking a torch in a cave, keeping two counts of air between you and the car ahead.

If you break down in a tunnel: hazard lights on, as close to the wall as possible, engine off and the key left in the ignition. Walk along the wall to the help point and call the traffic controller. If you must leave the tunnel (for example in a fire), use the escape door: follow the green signs.

Picture: 'Key in the lock, green leads you out.' You leave the key so rescue services can move your car, and the green lights pull you toward the safe door like a cinema exit sign.

In strong crosswind you must hold the wheel firmly with both hands and correct your steering. The wind can push you sideways across the road, so slow down to keep the car under control.

Think 'two hands on the helm' like a sailor in a storm: the harder the gust, the firmer your grip and the gentler your throttle. Less speed = less of a plaything for the wind.

In open spots such as dikes, bridges, viaducts and at the edges of woods or tunnel mouths, the crosswind suddenly hits or drops away. Be extra alert there: anticipate a gust the moment you leave shelter.

Remember: 'Behind the trees it's calm, past the trees the wind strikes.' Every time you shoot out of the shelter of a copse, viaduct or tall lorry, brace your steering for that invisible shove.

When overtaking (or meeting) a truck or bus in strong crosswind, you first fall into its wind shadow and then get hit by the full gust right after. Hold the wheel firmly and correct your steering the instant you pass the vehicle.

See it as a 'wind sandwich': beside the truck it's briefly still, but the moment you clear its nose the wind slaps you. Expect the smack and correct, so you don't swerve into the other lane.

Do not drive through water if you cannot judge its depth; water on the road can be deeper than it looks. Otherwise cross at walking pace, then gently test your brakes afterwards because wet brakes work less well. In aquaplaning: don't brake or steer, just release the throttle and let the car coast.

Remember the '3 W's: Walking pace, Wet-test brakes, Waft/coast.' Through puddles you crawl at walking speed, then dry your brakes with a light tap, and if you start to 'surf' (aquaplane) you simply lift off the gas and keep the wheel straight.

Vehicle knowledge

🛞📏1️⃣6️⃣The minimum tyre tread depth for a car is 1.6 mm.

Push a matchstick into the groove: if only the MATCH HEAD still fits (1.6 mm), you're at the legal limit! Chant 'one-point-six, no grip, big fix'.

🚗🔧4️⃣📅A new petrol car needs its first APK (roadworthiness test) at 4 years old.

Four wheels, four years! Each tyre 'ticks off' one year; once all 4 wheels have had their year, the car goes to the APK doctor for the first time.

1️⃣6️⃣🛞➕4️⃣🔧Lock in two numbers together: tyres 1.6 mm (minimum) AND first APK at 4 years.

Picture this: a car with 4 birthday candles on the hood (4 years → APK) rolls on tyres thin as a matchhead (1.6 mm). '1.6 and 4' — test time!

🪪📄🚗Always carry while driving: your driving licence, the vehicle registration (kentekencard) and a valid ID.

Three cards or no road: YOU (licence), your CAR (registration) and your NAME (ID). Keep the trio in your pocket, or the officer waves a fine.

⛽3️⃣🆚🚗4️⃣Note: a new diesel car needs its first APK after 3 years (petrol only after 4 years).

Diesel gets dirty faster, so one year sooner: 3 years diesel, 4 years petrol. Remember the step 3-4: Diesel = 3, Petrol = 4.

Before departure, check the tyres: enough tread (legal minimum 1.6 mm; 4 mm advised for winter tyres), correct tyre pressure and no damage. Under-inflation increases wear, braking distance and fuel use.

Remember '1-point-6': a matchstick head just fits head-down into the tread groove. If you can see the whole head, the tyre is too bald.

Before departure, check all lights: dipped beam, main beam, position lights, brake lights, indicators, fog lights and number-plate light. Faulty lighting makes you poorly visible and is an offence.

Walk a full 'lap around the car' with hazards and a helper pressing the brake: use a wall or shop window as a mirror. One lap = every lamp checked.

Regularly check the fluids: engine oil, coolant, windscreen washer fluid and brake fluid. Too little oil or coolant can damage the engine; too little brake fluid makes braking unreliable.

Memory aid 'O-C-W-B': Oil, Coolant, Washer, Brake fluid — four caps under the bonnet you tick off to give the trip your 'OK'.

In the Netherlands you don't have to carry a warning triangle (though it's handy). If your stationary car is an obstacle that approaching traffic can't see in time, place the triangle about 30 metres behind your car, towards the oncoming traffic — on the motorway too. If your hazard lights are flashing, the triangle isn't required.

Triangle = 3 corners → 30 metres, the same everywhere: in town and on the motorway, always behind your car. Hazard lights already flashing? Then the triangle can stay in the boot.

Hazard lights (warning flashers) are used to warn others of danger: during a breakdown, a crash, when stopped in a dangerous spot, or on the motorway when you must suddenly brake hard for a traffic jam ahead.

Think 'hazards = alarm, not park': the flashers shout 'watch out, danger!' — not 'I'm just stopping here because it suits me'.

Hazard lights must not replace your indicators: while the hazards are on, your normal turn signal no longer works. So switch them off before you drive on and need to indicate a direction.

Picture it: hazards mean 'both at once', so you can no longer 'speak' left or right separately. Want to say something with your arrow? Hazards off first.

Right of way

👉🚗🥇🛑At equal-priority intersections, traffic coming from the right has priority.

RIGHT is ROYALTY: the car on your right wears a golden crown, so you bow and brake. Rhyme it: 'Right goes, left waits!'

🚊👑⚡🛑Exception: the tram usually has priority — even when it comes from the left.

The tram is the KING who ignores the right-hand rule: far too heavy to brake, so even from the left it thunders straight through. Bow to the tram-king!

🔄🚗🥇⏳On a roundabout, traffic already on the ring has priority; you wait before entering.

The roundabout is a MERRY-GO-ROUND: whoever's already spinning keeps spinning — you only hop on when a gap opens up.

🚌🏙️🖐️🥇Within a built-up area you must give way to a bus pulling out from a stop.

In TOWN the bus is boss: blinker on at the stop and your foot hits the brake. Inside the built-up area you yield — outside town you don't!

🚦🔺❌👉The right-hand rule only applies at equal intersections — with no signs, no shark's teeth and no traffic lights.

See signs, SHARK'S TEETH (▽▽▽) or lights? Then the right-hand rule is OFF. Only on a totally bare junction does the right bite first.

At a pedestrian crossing (zebra) you must give way to pedestrians and drivers of invalid vehicles who are crossing or clearly want to cross. You need not stop for someone still standing far away.

Picture the zebra crossing as a real zebra: the moment its hoof touches the white stripe, you freeze. Still grazing in the distance? Drive calmly on.

Inside built-up areas you must let a scheduled bus that is signalling to pull away from a stop go first. Outside built-up areas this rule does not apply.

Remember 'the bus is boss in the built-up zone': inside town you yield, outside you don't. BUS and Built-up both start with B.

For a priority vehicle with blue flashing light and siren (police, fire, ambulance) you must always make room and give way, even when you yourself have right of way or a green light.

Blue flash AND siren = both on, you pull aside. A flashing light alone (like a tow truck's amber) grants no priority; the blue+sound duo rules.

At a level crossing with flashing red lights and/or closed or lowering barriers you must stop. You may only cross once the lights are off and the barriers are fully raised.

Red blinks = train knocks on the door. Two blinking red eyes are the train signalling 'here I come'; wait until both sleep and the barrier points to the sky.

At an unguarded level crossing (no barriers, no lights, usually marked with a St Andrew's cross) you must look carefully left and right yourself and always give way to an approaching train.

The St Andrew's cross (a slanted X) means 'cross only after looking'. No barriers, no lights = you are the barrier: look left, look right, and the train always wins.

When stopped for a closed crossing or a queue near a crossing, you may never drive so far forward that you block the tracks or the zebra. Stay behind it until you can clear it in one go.

Think 'never trapped on the tracks': only move onto the rails when the far side is clear. A car stuck on the rails is a tin can against a charging train.

Vulnerable road users

🚗↔️🚲When passing a cyclist, keep at least 1.5 metres of side clearance.

Picture a 1.5-metre door lying flat between your car and the bike. If the door touches the cyclist, you were too close — 'one-and-a-half, or they take a bath!'

🚚➡️🚲🙈When turning right, cyclists and pedestrians going straight have priority; always check your blind spot.

The big truck turns right and 'forgets' the cyclist hiding in its blind spot — the classic killer. Twist your head like an owl to the right: turn your neck or wreck a life!

🦯🧑‍🦯🛑A person with a white cane is blind or visually impaired — always give priority and extra space.

The white cane is a magic wand: the moment it appears, all traffic freezes still. White = wait, always.

🚌🏫🧒💨Pass a stopped bus at a stop slowly; children and people may suddenly cross.

Behind every stopped bus a hidden child is crouched, ready to rocket onto the road. Bus = brake reflex.

🏫🚸🐣🐣In a school zone drive extra slowly and alert; children can pop up everywhere.

Drive through a school zone as if the street is covered in baby chicks: one wrong move and 'peep' — so crawl and scan.

Special manoeuvres

🚗↩️🙇🌍When reversing, you give way to ALL other road users.

Reversing means going backwards into the world with no eyes in the back of your head, so you bow to EVERYONE. Going in reverse? You're the humblest driver on the road.

👀🫣🚗↔️Check the blind spot (over your shoulder) before pulling away and at EVERY lane change.

The blind spot is an invisible motorcyclist floating exactly where your mirror can't see. Turn your head, or he 'dies' against your door — that's why it's the DEAD angle.

🛣️🏃💨🤝On the motorway: match your speed on the acceleration lane (speed up) BEFORE you merge.

The acceleration lane is a long-jumper's run-up: sprint until you match their speed, THEN leap into the traffic. Jump too slow and you crash into the sandpit.

🅿️➡️🚦🙇Pulling away from the curb is a 'special manoeuvre': you give way to all traffic.

You were parked, so you're the newcomer crashing the party: wait politely until everyone passes, only THEN step onto the dance floor (the road). Newcomer = back of the queue.

🪞👉🫣🚗Every lane change: mirrors first, then indicate, then blind spot, then steer.

Mirror-Signal-Shoulder-Steer: four locks you open one by one before the door swings open. Skip one and it slams shut on the blind spot.

Reversing is a special maneuver (Art. 54 RVV): you must give way to ALL other road users, including pedestrians and cyclists, from both directions. You never have priority.

Think: 'Reverse = blind, so you always yield.' The one going backwards is driving blind, so they wait for everyone.

Before pulling away from the curb, check the blind spot by looking over your shoulder (not just mirrors). Signal and give way to through traffic.

The mirror lies, your shoulder doesn't. The blind spot is exactly where the cyclist your mirror can't see is hiding.

For every lane change: mirror - signal - blind spot (shoulder glance) - only then steer. Keep your speed and course steady while doing it.

Remember 'Mirror-Signal-Shoulder', the M-S-S order: look and tell first, act last.

When merging via the acceleration lane, YOU adapt to the traffic on the main carriageway. That traffic has priority; you find a gap and match your speed.

You're the guest at the party. The host (main traffic) stays put; you adapt and slip in between the guests.

On the acceleration lane you speed up to roughly the speed of the through traffic before merging, so you slot smoothly into a gap. Don't stop unless there's truly no other option.

The acceleration lane is a run-up, not a waiting room. Build speed first, then hop smoothly onto the moving train.

Traffic on the main carriageway is not obliged to let you in. If nobody makes room, YOU adjust (ease off or drive on to a gap); you may not force others to brake or swerve.

Don't wedge, zip. You ask for a spot, you don't demand it, so let anyone who gives no gap pass.

Environment and economical driving

With 'Het Nieuwe Rijden' (eco-driving) you shift up early: around 2000-2500 rpm in a petrol car, around 2000 rpm in a diesel. A high gear at low revs uses less fuel.

Picture a lazy cat that yawns at 2000 rpm: the moment the needle reaches there, it lazily clicks up a gear. Low revs = low fuel.

Look far ahead and anticipate the traffic. Reacting in good time means less hard braking and accelerating, which saves fuel and wear and is safer.

Drive as if binoculars are strapped to your nose: the farther you look, the softer your feet become on the gas and brake.

Let the car coast to slow down: lift your foot off the accelerator while staying in gear. The fuel supply is cut off completely, so you burn zero fuel.

Foot off the gas but still in gear = the fuel tap shuts. Coasting in neutral (clutch down) leaves the tap running.

Check tyre pressure regularly, at least once a month. Too low pressure raises rolling resistance, so you use more fuel, tyres wear faster and the car handles less safely.

Think of the first of the month as 'tyre day': soft tyres are like running on sand, costing extra effort and thus extra fuel.

Switch off the engine when stationary for a while, for example at an open (lifting or swing) bridge or a level crossing. Idling burns fuel while you go nowhere and harms the environment.

A running engine while parked is like a tap left open when you're not washing up: pure waste. Long wait? Key off.

Avoid unnecessary weight and air resistance: take out items you don't need and remove an empty roof rack or roof box. Extra weight and drag increase fuel consumption.

See an empty roof rack as an open parachute on your roof: it catches wind and pulls fuel from your tank. Take it off.

Motorway and autoweg

The emergency (hard) shoulder is only for emergencies: a breakdown or an accident. You may not drive on it, overtake on it, or stop there to wait or make a call.

Picture the hard shoulder as a hospital corridor: reserved for the ambulance and the broken-down car, never a shortcut for the impatient.

On the motorway (autosnelweg) only motor vehicles able by construction to go faster than 60 km/h are allowed. On the expressway (autoweg) the limit is faster than 50 km/h.

The longer word gets the bigger number: autoSNELweg (motorway) = 60, autoweg (expressway) = 50. Longer name, higher bar.

A red cross (X) on the matrix sign above a lane means that lane is closed. You may not drive under it and must leave that lane as soon as possible.

A red cross is like a wrong answer being struck out: that lane is 'crossed off', so switch out of it.

A green arrow pointing straight down on the matrix sign means: this lane is open. A flashing diagonal arrow means: leave this lane and move to the indicated side.

Green arrow = a green light to carry on; the flashing diagonal arrow gently 'pushes' you toward the side it points to.

Keep at least a 2-second gap to the vehicle ahead. Where distance markers (white chevrons/blocks) are painted on the road, keep at least 2 markers of space.

Say out loud 'twenty-one, twenty-two' the moment the car ahead passes a marker; if you reach it before you finish, you're too close.

A speed with a red ring on the matrix sign is a mandatory maximum speed, usually because of a traffic jam or danger ahead. You must obey it immediately.

The glowing number with the red ring isn't advice but a wall of law: red ring = obey now, danger ahead.
