If you don't have to drive Friday, leave your car in park.

That message from Constable Clint Stibbe with Toronto Police Traffic Service.

Stibbe tells Newstalk 1010's John Tory on the Live Drive the weather is going to "exceed many drivers' abilities as well as many vehicles' abilities".  He says driving on a day where the city could get as much as 25cm of snow is only putting you at greater risk to be in a collision.

Stibbe says fewer cars on the road makes it easier to clear the snow & for police to get to people who need help.

If you do have to drive, you can't just jump in your car, hit the windshield wipers & go.  Stibbe says you have to take the time to properly clear away the snow, or face the consequences. 

Drivers must have a clear view out of the sides of their vehicles & through the windshield.  You don't technically have to wipe off your back window, as long as you can use your side-view mirrors to see behind you.  But Stibbe says if you get tangled up in crash while your back window is snow-covered, you could be charged with careless driving.

When wiping the white blanket off your car, you can't just push the snow into the street either.  Stibbe says you could get a $110 fine.

If you are involved in a fender bender, Stibbe says your cell phone is your best friend.  He says you should take lots of pictures, which can capture much more detail than descriptions.  Stibbe suggests snaps of the scene, the damage & of the other driver's paperwork.

You don't need to call police if damage to both cars is under $1000.
