Lane Discipline Flashcards

What is the purpose of a 'crawler lane' on a steep road?

Answer: For slow-moving vehicles to use so faster traffic can pass

Crawler lanes are additional lanes on steep hills for slow-moving heavy vehicles so they do not block faster traffic.

On an expressway, what should you do when your exit is approaching?

Answer: Move to the left lane well in advance and follow deceleration lane markings

Move to the left lane well before your exit. Use the deceleration lane to reduce speed gradually. Never brake sharply on the main carriageway.

Can you straddle a chevron-marked area on the road?

Answer: No — they separate traffic flows and must not be entered

Chevron-marked areas bordered by solid white lines must not be entered. They are used to separate traffic flows for safety.

When a lane is marked with a 'left turn only' arrow on the road, what must you do?

Answer: You must turn left if you are in this lane

If you are in a lane marked with a directional arrow, you must follow that direction. If you need to go straight, move to the correct lane in advance.

What should you do when approaching a 'lane closed ahead' sign on the expressway?

Answer: Begin merging into the open lane gradually and in good time

When you see a lane closure sign, begin moving to the open lane gradually. Early merging is safer and reduces congestion.

What is the correct use of the acceleration lane when entering an expressway?

Answer: Use it to build up speed to match expressway traffic before merging

The acceleration lane is designed for you to build up speed to match the flow of expressway traffic, making merging safer and smoother.
