Interstate and intrastate trucks are governed by different sets of laws. Interstate traffic involves commercial carriers and vehicles that travel between states. This includes highway trucks, logging trucks, department store big rigs, United Postal Service trucks, FEDEX trucks and private charters like Greyhound buses.
Interstate trucks are regulated by the Department of Transportation and are covered by Federal Motor Carrier Safety Regulations. To see a complete list of federal highway rules and regulations, please visit the U.S. Department of Transportation website.
Intrastate traffic involves commercial carriers that are working and delivering goods within a single state. This includes school buses, fire trucks, garbage trucks, public transportation buses and vans, dump trucks, gas trucks, cement trucks and water trucks.
Intrastate trucks and buses are not regulated by the Department of Transportation (DOT), but by state laws. This means, if you are hit by a negligent school bus driver, your case for recovery will be subject by the laws of the state where the accident occurred.
Although intrastate trucks do not have to follow DOT regulations, a state can adopt certain rules into its own laws and statutes. For instance, the State of Florida has adopted numerous DOT regulations into its state laws, so intrastate truck drivers and companies will still be held against certain regulations if found to be negligent for causing an accident.
