There are some other signals that road users will use to communicate to you. You must know what these signals are and what to do when you see them.

Flashing lights and sirens

Emergency vehicles, such as an ambulance, fire engine or police car, use sirens and/or flashing red, blue, or blue and red lights. If an emergency vehicle is coming towards or behind you with sirens and/or flashing lights, you must pull over, stop if necessary, and allow it to pass.

Police officer directing traffic

When a police officer is directing traffic, you must stop or go where the officer directs you. A police officer’s directions overrule:

  • traffic signals
  • road signs
  • the give way rules.

If a police officer is controlling an intersection, be careful to get into the correct lane. If you don’t, you may have to go the wrong way.

Show the officer where you want to go by using your indicators.
