Does Montana have a chain law?

You will not get whacked with a fine for driving in Montana without chains under normal weather conditions. However, if you enter a posted "chain area" without chains you will get slugged with an exorbitant fine if you cause an accident. In posted areas, you are required to cover one tire on one side of the drive axle. To play it safe call ahead for road condition updates at (406) 444-6339.
