How much in advance of a turn or lane change should you signal?
Show Answer & Explanation
Correct Answer: B. Well before the turn or lane change, so others know your intent
Early signalling gives following drivers, cyclists, and pedestrians time to predict your action. Late signalling is a surprise and a top cause of sideswipes and rear-end collisions. Ontario recommends 30 metres advance in city driving, more on highways.
Why the other answers are wrong
- A.At the moment you begin the manoeuvreSignalling at the manoeuvre is too late — others have no warning.
- C.Only if traffic is closeEven with no visible traffic, unseen drivers or cyclists may be approaching.
- D.Immediately before crossing the lineSignalling just before crossing a line gives no advance warning.
