Speeding is one of the leading contributors to serious accidents on U.S. roads—especially for large commercial vehicles. To reduce truck speeding and improve road safety, drivers and fleets need to understand and follow posted limits. Driving too fast not only cuts down reaction time but also increases the severity of crashes.

The speed limits for trucks and cars vary by state in the United States. Here is a general overview of the speed limits for all states, according to the Insurance Institute for Highway Safety.
