There are a variety of other signals that other 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.

Doctors, nurses or midwives on urgent business may use a roof-mounted green flashing light. If you see these, you must pull over and allow the vehicle to pass.
When service vehicles, such as tow trucks and road maintenance vehicles, use flashing yellow lights, they are warning you to be careful around them. When you see these lights, slow down and be prepared to stop, if necessary.
Yellow flashing lights on a service vehicle
Oversize vehicles may use flashing yellow lights and pilot vehicles may use flashing yellow and purple lights. These mean you must pull over and, if necessary, stop, and let all the vehicles pass. For more information about oversize vehicles, see Vehicle-mounted signs.
Red flashing signals outside a fire station or airport mean you must stop and remain stopped until the lights stop flashing.
Flashing red signals
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.
