Commercial truck roadside splits at the weight class. Light-duty commercial trucks (3/4-ton, 1-ton — Ford F-250/350, Chevy 2500/3500, Ram 2500/3500, work vans like Sprinter and Transit) are serviced by standard roadside operators with light-duty equipment.
Medium-duty trucks (Ford F-450/550, Ram 4500/5500, chassis cabs) require slightly heavier equipment but are still within most roadside operators' capability.
Heavy-duty Class 7-8 trucks (semi-tractors, large delivery trucks, dump trucks, garbage trucks) require heavy-duty roadside services — specialized operators with heavy-duty tow trucks and heavy-duty mechanical capability.
Most light-duty roadside services don't operate heavy-duty trucks. If your fleet mixes light-duty and Class 7-8, you need two providers or a provider with both capabilities.
Fleet accounts for commercial trucks often have consolidated billing across vehicle classes, but the actual service work routes to different operator tiers based on weight class.
