Before the move
How we plan a Colorado load
Every Colorado move starts with a CDOT extra legal permit. Our permitting team checks the size, weight and route against the Colorado rules and the CDOT restriction map, then sets the pilot vehicles and travel windows the permit calls for.
Over 17'6"H or 130'L we file the route survey with the application, and over 17'H we book the signal contractor.
