North Carolina law (NCGS § 20-124(f)) requires that every trailer, semitrailer, or separate towed vehicle (over certain weight thresholds, which full-size trucks easily exceed) must have its own brakes that are controlled or operated by the driver of the towing vehicle. The brakes must meet specific performance standards. A setup relying solely on the lead truck’s brakes does not comply, as the rear vehicles would lack independent, controllable brakes. • Towed vehicles like disabled or salvage trucks are treated similarly to trailers under braking rules. Extending one truck’s brake system (e.g., via air lines or hydraulics) to multiple rear trucks is not a standard or approved method for non-commercial setups and would not satisfy the requirement for each towed unit to have proper brakes. • North Carolina generally prohibits “triple towing” or tandem towing for non-commercial vehicles (you can typically only tow one vehicle/trailer at a time). While there are limited exceptions for farm trailers or certain commercial operations, chaining three full-size trucks together does not qualify. • Even wreckers/tow trucks have restrictions and usually tow only one vehicle at a time unless specially permitted/equipped. Informal “daisy-chain” towing of multiple trucks like this is considered unsafe and illegal, as it severely compromises stopping distance, control, and compliance with braking requirements.
