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.
If an emergency vehicle, such as an ambulance, fire engine or police car, is coming towards you or behind you, and is using sirens and/or flashing red, blue, or blue and red lights, you must pull over and, if necessary, stop and allow it to pass.
If a police car is following you with its siren on and/or flashing blue, or blue and red lights, you must pull over and stop as soon as possible.
If asked to, you must give a police officer:
If a vehicle is following you with flashing blue lights, you must pull over and stop as soon as possible. Flashing blue lights are used by customs, fisheries and marine reserve officers. These officers have the right to stop vehicles.
Doctors, nurses or midwives on urgent business may use a roof-mounted green flashing light. If you see these lights, you must pull over and allow the vehicle to pass.
When service vehicles, such as tow trucks and road maintenance vehicles, use flashing amber lights, they're warning you to be careful around them. When you see these lights, slow down, and be prepared to stop if necessary.
Oversize vehicles may use flashing amber lights and pilot vehicles may use flashing amber and purple lights. You may need to pull over or stop to let the vehicles pass.
Red flashing signals outside a fire station or airport mean you must stop and remain stopped until the lights stop flashing.
When a police officer is directing traffic, you must stop or go where the officer directs you. A police officer’s directions overrule:
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.
