Any overwidth load moving after dark on black coded routes, if width exceeds 10’, must also be preceded by such a pilot/escort vehicle. Any overwidth load moving after dark or on weekends on a red coded route of the Pilot/Escort Vehicle and Travel Time Requirements Map must be preceded by an escort vehicle displaying a rotating or flashing amber light to warn other traffic of the presence of the hazard.
Escort vehicle requirements can differ significantly by state in terms of mandatory driver qualifications, training, certifications, vehicle weights, obligatory signage/flags/lighting, necessary onboard equipment, and more. The ODS team can provide you with all additional requirements specific to your route.
