When can you drive in an emergency lane on the expressway?
Answer: Only in a genuine emergency such as a vehicle breakdown
The emergency lane (road shoulder) may only be used for genuine emergencies such as a vehicle breakdown. Using it to beat traffic is illegal.
A lane on your left is ending and merging into yours. Who should give way?
Answer: The merging vehicle must adjust speed to fit into your lane safely
The vehicle in the ending lane must adjust their speed to merge safely into the continuing lane. However, courteous drivers in the continuing lane will cooperate.
You are about to change lanes on the expressway. What is your blind spot?
Answer: The area to the side of your vehicle not visible in mirrors
The blind spot is the area alongside and slightly behind your vehicle that cannot be seen in rear-view or side mirrors. Always turn your head to check.
When should you signal before changing lanes?
Answer: At least 3 seconds before you begin to change lanes
Signal at least 3 seconds before changing lanes to give other drivers adequate warning of your intention.
What does 'lane filtering' by motorcycles refer to?
Answer: Motorcycles weaving between lanes in slow or stationary traffic
Lane filtering is when motorcyclists ride between lanes of slow-moving or stationary traffic. While common, it must be done carefully and within legal guidelines.
You are in the correct lane to turn right but the vehicle beside you also starts turning right from the wrong lane. What should you do?
Answer: Allow them to complete the turn to avoid a collision — safety first
Even though you are in the correct lane, avoiding a collision is always the priority. Let them complete the manoeuvre safely, then continue.
