MileCheckWhich states have a lower speed limit for trucks?
California, Illinois, Indiana, Michigan, Oregon, Virginia and Washington set a lower speed limit for trucks than for cars on at least some highways, by the official pages in the table. This is not a list of every state. We make no claim about a state that is not on it.

What this page does not say
A state that is not in the table may still set a lower limit for trucks on some roads. We have not verified every state, so we do not say trucks follow the car limit anywhere. Posted signs set the limit on a segment.
