When towing another vehicle you are required to use what?

When towing another vehicle, you are required to use a tow bar or a tow strap that is rated for the weight of the towed vehicle. Additionally, safety chains should be employed to provide a secondary connection, ensuring that the towed vehicle remains secure in case the primary connection fails. It's also important to have proper signaling devices, such as functioning brake lights and turn signals, to communicate with other drivers on the road.
