A towing service couples one vehicle to another so that one vehicle can be pulled behind the other. The towing source is a usually a truck. The coupling may be a chain, rope, bar, platform, or some other means to keep the two vehicles together when in motion.
The most commonly seen towing service is used for moving a broken down or seized vehicle via a wrecker, or tow truck. But, any object can be towed. Many countries have standards for tow trucks to ensure the safety and security of towing a vehicle. The machinery of an automated tow truck is situated at the back of the vehicle. Having a high ten steel cable with a hook on the back allows them to either pull the vehicle onto the platform or raise the front wheels, allowing only the back ones to be left on the ground.
