Flatbed tow trucks are a popular type of wrecker that have an empty, flat platform for placing disabled vehicles on rather than pulling them behind the truck with sliding wheels on the pavement. They utilize a hydraulic lifting system to pull vehicles onto the back platform and tie them down securely. Flatbeds do not lift vehicles by the front or rear end like typical hook and chain and wheel lift tow trucks. This method prevents potential damage to drivetrain components and suspensions that dangling chains and straps can cause during transport. Flatbed towing is highly recommended for modern unibody vehicles, 4WD/AWD vehicles, vehicles with lowered suspensions, cars with body modifications, vintage vehicles, and front-wheel drive cars. Additionally, flatbed trucks have the capacity to tow much larger vehicles than standard tow trucks including full-size buses, tractors, heavy equipment, and commercial trucks. Vehicle owners can specify the need for flatbed towing when arranging for roadside assistance or towing services.
