It depends on the state in question. The only state where I even recall this type of law (that you can drive at any speed that is "safe" but that the posted limit is optimal) was either Montana or one of the Dakotas. Otherwise, the states that I've driven in use the posted limit as a maximum speed. Many highways also have a minimum posted speed. Stephen Gallagher
