Be safe and test the conditions of the road you're driving on.

On Tuesday, in my job driving a truck for the city of Minneapolis, I treated city streets with a mixture of salt and sand. One of the streets on my route has four hill streets on it, and on Tuesday there were cars stuck on every one of them.

I put sand around each vehicle, and they were on their way. What puzzled me was that cars were still trying to come up the hills after seeing the others stuck.
