When is a light tap of the horn appropriate?
- A.To hurry a slow driver at a green light
- B.As a greeting to other truck drivers
- C.To warn another road user who may not see you, such as a driver about to pull out
- D.Whenever traffic is heavy
Correct answer
C. To warn another road user who may not see you, such as a driver about to pull out
Why
The horn is a warning tool, best used briefly when someone clearly does not know you are there. Using it aggressively or constantly just startles people and adds to confusion.
