The US National Maximum Speed Law of 55 mph (miles per hour) remained in effect until what year?

Yana, My son, when he was four yrs. old loved to stand on the drivers seat and grasp the steering wheel and make manical faces and sing that song. When we were parked of course.

Anyone else hearing I Can't Drive 55 ? Thank Sammy Hagar !

Player #6103765, regulated by states now.

What is the speed limit there now?
