So keep a warm blanket or two in the trunk, spare hat and gloves, flashlight, and perhaps some non-perishable food. Just in case. Motorists need to drive with extra care and know their limits. And there are differences with light snow, heavy snow, slush and ice. So slow down, and keep a greater distance from other cars and roadside hardware.
Snow is tricky, but ice is downright treacherous.
It can be dificult to see, blending in with the road or covered by snow. It can melt during the day but re-form at night. And bridges are especially vulnerable. So leave plenty of room for stopping distance. So if you have a choice, select the vehicle that's best for snow.
