Watch for Emergency Vehicles
There are two situations where motorists will encounter an emergency vehicle on our roads and highways: when a police, fire or ambulance vehicle is approaching from either direction or when any of these vehicles, with their lights flashing, is stopped in the same direction on the road or the shoulder ahead. Fire and ambulance vehicles will use flashing red lights and police vehicles may use either flashing red lights alone or a combination of flashing red and blue lights.
As of June 4, 2007, police department vehicles may use flashing blue lights in combination with flashing red lights. Some police services will continue using flashing red lights only.
Motorists should respond to police vehicles with flashing blue and red lights in the same way they respond to flashing red lights.
Reacting to an approaching emergency vehicle
As required by law, a motorist who sees or hears an emergency vehicle must clear the way. When a police, fire or ambulance vehicle is approaching from either direction, with lights flashing or siren on, motorists are required to pull to the right, and if possible, stop. This is especially important during peak traffic times. Also, motorists must yield to an emergency vehicle at intersections.
It is also illegal to follow within 150 metres a fire vehicle or ambulance responding to a call.
Failing to pull over and stop for an approaching emergency vehicle can result in the following:
Fine - $90 ($125 in a Community Safety Zone), plus 3 demerit points on your driving record upon conviction.

Approaching a stopped emergency vehicle
Enforcing the law and providing emergency assistance often require emergency vehicles to park in a lane or on the shoulder of a road or highway.
To increase safety, Ontario's
Highway Traffic Act now requires motorists approaching a stopped police, fire or ambulance vehicle with its lights* flashing to slow down and pass with caution. This applies to all police, fire and ambulance vehicles that are stopped in the same direction of travel, either in a lane or on the shoulder of a road or highway.
* Fire vehicles and ambulances use flashing red lights. Police vehicles may use flashing red lights or a combination of flashing blue and red lights.
First offence - $400 to $2,000, plus 3 demerit points upon conviction.
Subsequent offence (within 5 years) - $1,000 to $4,000, possible jail time up to 6 months and possible suspension of driver's licence for up to 2 years.
Road Safety. It starts with you.
