Speed Limits: practice questions

Correct answer: By the posted speed-limit signs for that road

The legal limit for a road is the figure shown on its speed-limit signs. You must not exceed it, and you should drive below it whenever conditions require.

Reference: RTA — Driving Safely in Dubai handbook, speed limits (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Drive slowly, expecting pedestrians and parked cars

Residential streets carry low limits because children, pedestrians and reversing cars are common. Even without a posted sign, keep your speed low and stay ready to stop.

Reference: RTA — Driving Safely in Dubai handbook, residential speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: True

The limit is the most you may legally do in good conditions. In rain, fog, heavy traffic or poor visibility you must drive slower; the safe speed is often well below the posted figure.

Reference: RTA — Driving Safely in Dubai handbook, speed and conditions (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: There is no tolerance — exceeding the posted limit at all can be fined

Abu Dhabi enforces its limits strictly with no speed tolerance, so exceeding the posted figure at all can attract a fine. Treat the posted number as the true maximum.

Reference: Abu Dhabi Police / ITC — speed enforcement, no buffer (https://www.adpolice.gov.ae, verified 2026-06)

Correct answer: Still aim to stay at or below the posted limit

A tolerance is not permission to speed; the posted limit is still the safe and legal target. Tolerances can change and are not assured, so a safe driver stays at or below the sign.

Reference: RTA — Driving Safely in Dubai handbook, speed tolerance (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: It increases stopping distance sharply

Stopping distance grows much faster than speed: doubling your speed roughly quadruples the distance needed to stop. Higher speed leaves far less room to avoid a hazard.

Reference: RTA — Driving Safely in Dubai handbook, speed and stopping distance (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: You must not drive slower than that speed in normal conditions

A minimum-speed sign means you must keep up at least that speed in normal conditions. Driving too slowly on a fast road obstructs traffic and is dangerous, though you must still slow for hazards.

Reference: RTA — Driving Safely in Dubai handbook, minimum speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: It forces others to brake and overtake, raising crash risk

Large speed differences are dangerous. A slow car in the fast lane makes others brake hard and weave around it. Keep right when not overtaking and match a safe, legal speed with the flow.

Reference: RTA — Driving Safely in Dubai handbook, lane discipline and speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Slow down to the new limit before reaching the zone

Reduced limits at roadworks protect workers and account for lane shifts and debris. Slow to the new limit before you enter the zone, not after.

Reference: RTA — Driving Safely in Dubai handbook, roadworks speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: True

Lower limits near schools give drivers time to react to children who may cross suddenly. Obey the reduced limit, especially at drop-off and pick-up times.

Reference: RTA — Driving Safely in Dubai handbook, school zones (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Well below the posted limit, matched to visibility and grip

The posted limit assumes good conditions. In fog or rain you can see and stop over much less distance, so you must slow well below the sign to a speed you can control.

Reference: RTA — Driving Safely in Dubai handbook, speed in adverse weather (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Your speed — the faster you go, the larger the gap needed

The faster you travel, the more distance you cover before you can react and brake, so the safe gap to the car ahead grows with speed. A common guide is at least a two-second gap, more in poor conditions.

Reference: RTA — Driving Safely in Dubai handbook, following distance (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Encourage drivers to keep to safe, legal speeds

Speed enforcement cameras exist to deter speeding and reduce crashes. Assume any road may be monitored and keep to the limit everywhere, not just where you expect a camera.

Reference: UAE Government portal — Road safety, speed enforcement (https://u.ae/en/information-and-services/justice-safety-and-the-law/road-safety, verified 2026-06)

Correct answer: Slow down before the bend, then drive through steadily

Reduce speed before you enter a bend, while the car is still straight. Braking hard mid-corner can make the car skid; entering at a controlled speed lets you steer smoothly through.

Reference: RTA — Driving Safely in Dubai handbook, cornering (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Service roads have more junctions, turns and parked cars

Service roads serve buildings and have frequent entries, turns and parked vehicles, so their limits are lower than the main road. Always follow the limit for the road you are actually on.

Reference: RTA — Driving Safely in Dubai handbook, road types and limits (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Reduces reaction time and increases both crash chance and severity

At higher speed you have less time to react, need much more distance to stop, and any impact carries far more energy. Speeding raises both the likelihood and the seriousness of a crash.

Reference: UAE Government portal — Road safety, dangers of speeding (https://u.ae/en/information-and-services/justice-safety-and-the-law/road-safety, verified 2026-06)

Correct answer: Need significantly more distance to stop

Higher speed means more distance is covered during reaction time and much more braking distance, because braking distance rises with the square of speed. The faster car needs significantly more room to stop.

Reference: RTA — Driving Safely in Dubai handbook, braking and speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: False

The speed limit applies at all times, including while overtaking. If you cannot complete a safe overtake within the limit, you should not attempt it.

Reference: RTA — Driving Safely in Dubai handbook, overtaking and speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Keep a steady speed within the limit and avoid sudden changes

Smooth, steady speed within the limit is predictable for other drivers and reduces crash risk. Frequent acceleration and braking unsettle the traffic around you.

Reference: RTA — Driving Safely in Dubai handbook, highway speed management (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Ease off gently and bring your speed back within the limit

Check your speedometer regularly. If you have crept over the limit, lift off smoothly to slow down — sudden hard braking can be dangerous to traffic behind you.

Reference: RTA — Driving Safely in Dubai handbook, speed awareness (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: They need much longer to stop and are harder to control

A loaded heavy vehicle has much greater momentum, needs a far longer distance to stop and is less stable in turns, so lower speed limits reduce the risk it poses.

Reference: RTA — Driving Safely in Dubai handbook, heavy vehicle limits (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: True

Average-speed systems time you between two points, so braking only at a camera does not help. The reliable approach is to stay within the limit along the whole road.

Reference: UAE Government portal — Road safety, speed enforcement methods (https://u.ae/en/information-and-services/justice-safety-and-the-law/road-safety, verified 2026-06)

Correct answer: Slow down to the lower limit before and on the exit ramp

After fast driving your sense of speed adapts, so you may feel slower than you are. Check the speedometer and reduce to the exit limit, as ramps are often tight and may end at a junction.

Reference: RTA — Driving Safely in Dubai handbook, leaving the highway (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Even at a legal speed you have no room to stop if it brakes

Keeping to the limit is not enough on its own. Without a safe gap, a sudden brake by the car ahead leaves no time to react, so a rear-end crash can happen even at a legal speed.

Reference: RTA — Driving Safely in Dubai handbook, speed plus following distance (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: There is less room to recover from a mistake and exits are limited

Tunnels and bridges are confined, with limited space to manoeuvre and few escape routes if something goes wrong, so lower limits give more margin for safety.

Reference: RTA — Driving Safely in Dubai handbook, tunnels and bridges (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Warn you that you are too fast so you slow down

Driver-feedback signs flag when you are over the limit so you can correct your speed before a hazard or a fixed camera. Treat the red display as a prompt to slow down.

Reference: RTA — Driving Safely in Dubai handbook, driver feedback signs (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Reduce speed early and smoothly

Easing off early gives you and the drivers behind time to slow safely. Late, hard braking risks losing control and being hit from behind.

Reference: RTA — Driving Safely in Dubai handbook, anticipation and speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: True

Posted limits and enforcement tolerance can vary between emirates. Do not assume one emirate's limit applies in another — always follow the signs on the road you are on.

Reference: UAE Government portal — Road safety, emirate-specific limits (https://u.ae/en/information-and-services/justice-safety-and-the-law/road-safety, verified 2026-06)

Correct answer: Traffic is light and flowing steadily on an open road

Cruise control helps hold a steady legal speed on open, free-flowing roads. In heavy traffic or poor weather it reduces your readiness to react, so drive manually there.

Reference: RTA — Driving Safely in Dubai handbook, cruise control (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Are set to keep all road users safe

Limits are based on the road, its hazards and stopping distances, and are set to protect everyone — drivers, passengers, pedestrians and cyclists alike. Obeying them is a safety choice, not just legal compliance.

Reference: UAE Government portal — Road safety, purpose of speed limits (https://u.ae/en/information-and-services/justice-safety-and-the-law/road-safety, verified 2026-06)

Correct answer: Match the flow of traffic on the main road safely

Use the acceleration lane to build up to a safe speed close to the traffic flow, then merge into a gap without exceeding the limit. Entering too slowly forces others to brake suddenly.

Reference: RTA — Driving Safely in Dubai handbook, merging speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: True

Excessively slow driving disrupts the flow, causes others to overtake riskily and can be an offence where a minimum speed applies. Match a safe speed to the road and conditions.

Reference: RTA — Driving Safely in Dubai handbook, minimum/flow speed (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Lower, because grip and braking are reduced

A wet surface cuts tyre grip and lengthens braking, and high speed can cause aquaplaning. Reduce speed below the dry-road figure and increase your following distance in the rain.

Reference: RTA — Driving Safely in Dubai handbook, wet roads (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: Stopping distance and impact energy both rise quickly with speed

A little extra speed adds meaningfully to stopping distance and sharply increases the energy in a collision, so a pedestrian hit at a slightly higher speed is far more likely to be seriously hurt.

Reference: UAE Government portal — Road safety, speed and pedestrian injury (https://u.ae/en/information-and-services/justice-safety-and-the-law/road-safety, verified 2026-06)

Correct answer: Change the limit to suit traffic, weather or incidents ahead

Variable limits let operators lower the speed when there is congestion, bad weather or a crash ahead. The displayed figure is the legal limit at that moment and must be obeyed.

Reference: RTA — Driving Safely in Dubai handbook, variable speed limits (https://licensing.rta.ae/handbook/DrivingSafelyInDubaiEN.pdf, verified 2026-06)

Correct answer: A buffer of 20 km/h above the posted limit

Dubai applies a speed buffer of 20 km/h: a fine is generally triggered only once you exceed the posted limit by more than 20 km/h. This still means you should drive at or below the sign, as the buffer is not a permitted extra limit.

Correct answer: As the absolute maximum — there is no speed buffer

Unlike Dubai, Abu Dhabi applies no speed buffer: the posted limit is the absolute maximum, and exceeding it even slightly can result in a fine. Always keep to or below the sign.

Reference: UAE Government portal — traffic fines schedule, speed tolerance (Abu Dhabi) (https://assets.u.ae/api/public/content/a6279069a68b41e58c266703a7d519c9, verified 2026-06)

Correct answer: 80 km/h

Heavy vehicles are capped at 80 km/h on highways, below the limit for cars, because they need much longer to stop and are harder to control at speed. Many are fitted with speed limiters to enforce this.
