Provincial police are urging drivers to be mindful of Ontario's so-called "move over law."
That's after OPP say they've laid 763 charges under the law so far this year.
The law was established in 2003 and requires drivers to slow down and proceed with caution when approaching an emergency vehicle parked on the side of the highway with its lights on.
If the highway has more than one lane, the law requires the driver to move over and leave one lane between their vehicle and the parked emergency vehicle when that can be done safely.
Police say they'll be conducting an education and enforcement campaign on the law over the upcoming long weekend.
