You drive down a residential street. In which of these situations is it lawful to sound your horn?
Correct answer: A child on a bicycle starts to roll out of a driveway toward your lane.
Why
Every car must have a horn in good working order that others can hear from at least 200 feet. The horn is a safety device, and it can save your life when another road user has not seen you. Use it the moment it is needed as a warning, but never to show anger, to call someone or to greet a friend.
