Speed Limits and Zones Flashcards

What happens to the severity of pedestrian injuries as vehicle speed increases from 30 km/h to 50 km/h?

Answer: The risk of fatal injury increases dramatically — from about 10% to about 80%

At 30 km/h, about 10% of pedestrian collisions are fatal. At 50 km/h, this rises to about 80%. Even small speed reductions save lives.

Your vehicle's speedometer reads 60 km/h. Is your actual speed likely to be exactly 60 km/h?

Answer: No — speedometers typically read slightly higher than actual speed

Most speedometers are calibrated to read slightly higher than the actual speed. This is a safety margin built in by manufacturers.

What is the purpose of road humps in residential areas?

Answer: To physically force drivers to reduce speed for safety

Road humps are traffic calming devices designed to physically force drivers to slow down in areas with high pedestrian activity.

On a road with a 50 km/h limit, can you be penalised for driving at 50 km/h if conditions are dangerous?

Answer: Yes — you must drive at a speed appropriate for conditions, even if below the limit

Driving at the speed limit in dangerous conditions (fog, rain, crowds) can be considered dangerous driving. You must adjust speed to conditions.

What does the demerit point system do in relation to speeding offences?

Answer: It accumulates points per offence — too many leads to licence suspension

Singapore's demerit point system adds points for each offence. Accumulating 24 or more points within 24 months leads to licence suspension.

What speed should you not exceed when passing a road accident scene?

Answer: A slow, cautious speed appropriate for the situation

When passing an accident scene, slow down significantly. Emergency workers and injured people may be on the road, and debris may be present.
