Watch out in parking lots and crossing sidewalks. Ice does not melt off these areas as well as well travelled roads do.

Standing water on your usual route may indicate a new pothole developed. I've seen 8" deep and a foot across potholes show up with the space of a weekend.

Car drivers do not see the road lanes and edges as well as we do when snow covered. Following what you plainly see as the road edge may have you in the middle of the travelled "lane" on curves as cars cut corners and drive across shoulders. Your travelled "lane" may quickly change from smooth tarmac to gravel, debris, road edges, dropoffs and potholes.

Unless you have studs as soon as both tires are on black ice you have zero friction and traction. Packed polished snow at back street stop signs can freeze up icy and send you to the ground. Trust me.

Sometimes fresh powder is better to ride on than driven on snow that packs and the shears as you ride across it.
