Dot Numbers

Effective April 1, 2006, new regulations take effect for commercial vehicle carriers that operate only within the state of Idaho.  Carriers whose GVWR or combination GVWR of 26,001 are required to have and display an Intrastate DOT number.  Carriers who are 26,000 or less and stay only with the state of Idaho, are no longer required to have an Intrastate DOT number. Carriers who haul hazardous materials that require placards or passenger carriers still need an Interstate or Intrastate DOT number.  Contact Commercial Vehicle Safety at (208) 884-7220 or see the attached information for a summary of the regulation changes.
