New South Wales · Driver Knowledge Test (DKT) · Road rules

When are you allowed to use your horn?

The answer

  • Any time before 10pm
  • To hurry up slow drivers
  • To greet people you know
  • Only to warn other road users or animals of your approach Correct

Why that's the answer

The horn may only be used to warn other road users or animals of your vehicle's approach — not to express frustration or say hello.
