When Is a Pilot Car Required? Rules by State & Province
Escort vehicle requirements depend on the state or province. These links go to the official agency. We only link official sources and don't restate numbers we can't verify.
What usually triggers an escort
Most agencies set escort requirements based on a load's width, height, length, overhang and weight, the type of road (interstate, two-lane, city), and time of day or weather. Some require certified escort drivers, height poles or police escorts above certain sizes. Thresholds differ by state and change over time, so check the official page for your exact load and route.
