This includes emergency vehicles, tow trucks attending to in-traffic or on-the-shoulder interventions and surveillance vehicles equipped with flashing yellow arrow signs.
CAA's Cedric Essiminy said a dozen law enforcement and emergency workers are injured in roadside incidents each year. He said sometimes, it's the emergency vehicles that distract drivers.
"You tend to look at it to see what's happening."
The rest of Canada has already implemented similar laws. In Quebec, the government followed suit after a police officer was hit and killed by a truck last December.
According to the CAA's website, the Sûreté du Québec recorded about 215 accidents involving vehicles stopped on the road, four of which were fatal and 13 that lead to injuries.
Provincial police spokesman Yves Bouchard said every law enforcement and emergency worker has had their own close call on a road.
Drivers who fail to abide by the law can face fines from $200 to $300 and receive a penalty of four demerit points.
The provincial government has also funded commercials and other advertisements to make drivers aware of the new rules of the road.
