There's been a few changes to the Motor Vehicle Act when it comes to emergency responders.
If a police officer, fire fighting vehicle or ambulance are stopped on the highway and are flashing their lights, you must slow down and move over to the left away from the emergency vehicle.
If there are two or more lanes of traffic, you must move into another lane for safety. The fine for not slowing down and moving over for an emergency vehicle is $292.50 and 3 demerit points.
