When is it appropriate to sound your vehicle's horn?
Correct answer: B – To give a reasonable warning of an immediate collision danger
A vehicle horn may be used as a reasonable warning. The driver manual recommends a sharp blast when necessary to alert someone to an immediate danger of collision. Unnecessary, unreasonably loud, or harsh horn use is prohibited, and motorists should not blast the horn merely because they are approaching a bicyclist.
