BTT Lane Discipline 4 — Questions and Answers
Question 1: What is the purpose of a 'crawler lane' on a steep road?
- For vehicles to park
- For slow-moving vehicles to use so faster traffic can pass (Correct answer)
- For emergency vehicles only
- For bicycles and motorcycles
Correct 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.
Question 2: On an expressway, what should you do when your exit is approaching?
- Brake sharply and move to the exit lane
- Move to the left lane well in advance and follow deceleration lane markings (Correct answer)
- Stop on the expressway and reverse if you miss it
- Use the right lane to exit
Correct 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.
Question 3: Can you straddle a chevron-marked area on the road?
- Yes, they are just advisory markings
- No — they separate traffic flows and must not be entered (Correct answer)
- Only when overtaking
- Only during off-peak hours
Correct 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.
Question 4: When a lane is marked with a 'left turn only' arrow on the road, what must you do?
- You may go straight if there is no other traffic
- You must turn left if you are in this lane (Correct answer)
- The arrow is advisory only
- You may change lanes at the last moment
Correct 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.
Question 5: What should you do when approaching a 'lane closed ahead' sign on the expressway?
- Speed up to pass before the closure
- Begin merging into the open lane gradually and in good time (Correct answer)
- Stop and wait for instructions
- Continue in the closing lane until the last moment
Correct 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.
Question 6: What is the correct use of the acceleration lane when entering an expressway?
- Stop and wait for a gap in traffic
- Use it to build up speed to match expressway traffic before merging (Correct answer)
- Drive slowly and merge when possible
- Use it as an additional lane for slow vehicles
Correct 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.
