The MTO recommends checking your vehicle before leaving and keeping a winter survival kit in your car. The kit should include things like water, a flashlight, blankets, extra clothes, winter boots, food, and a phone charger.
They also suggest keeping your gas tank at least half full and using winter tires.
In addition to being prepared, the MTO says to slow down and drive according to the weather conditions. This includes keeping a safe distance back from snow plows, and to avoid passing them on the roads as it can be dangerous.
