The door prize injures hundreds of cyclists each year.
First Prize: Congratulations, you just injured a cyclist by opening your door into traffic.
Other Prizes: Fines and Demerit points ($110 fine and 2 demerits in Ontario) and a quite possibly a court case!
What to do:
Drivers/Passengers: Look back over your shoulder before you open your car door, every time – Cyclists ride faster than most people think! Don’t leave your door open in traffic.
Cyclists: Ride out from parked cars and maintain a straight path visible to motorists. Watch for drivers or passengers when cars are parked or stopped and be prepared to take evasive action. Moderate your speed in street parking areas.
