Trucking Law and Legal Definition

A truck is a motor vehicle designed, used or maintained primarily for the transportation of property. States regulate the height, length, width or weight of any truck, semitrailer truck or trailer under maximum limits prescribed by law. State officers are authorized to measure or weigh trucks, either by means of portable or stationary scales, and may require such vehicle to be driven to the nearest stationary scales, in the event such scales are within a certain distance of miles.

Interstate and/or intrastate trucking company or passenger-carrier company must be in compliance with Federal Motor Carrier Safety Regulations, Federal Hazardous Materials Regulations, and any state regulations. The U.S. Department of Transportation (DOT) requires the following documents to be filed:

  • Interstate Operating Authority (MC / MX)
  • U.S. DOT Number
  • Process Service Agent
  • Haz-Mat Certificate
