How to tow a car safely and legally in the UK

Towing a car in the UK is legal only when both drivers follow strict rules on signs, distances and lighting to keep everyone safe on the road.

Towing rules in the UK

Both vehicles must display an 'On Tow' sign at the rear of the towed car. The maximum distance between the vehicles is 4.5 metres when using a rope or chain. If the gap exceeds 1.5 metres the rope or chain must be made visible with a coloured flapping cloth. The person in the broken-down vehicle must be a qualified driver. At night the towed vehicle must use its normal lights. These rules come from established roadside advice and help prevent accidents during an emergency tow. Always plan the route in advance and avoid motorways if possible unless the towed vehicle can maintain safe speed. Check your MOT status before setting off using the free service at CheckMOT to avoid any legal issues on the journey.

Essential safety equipment

Carry a suitable tow rope or strap, a warning triangle and high-visibility clothing. These items help other road users see the tow clearly and reduce risk during an emergency stop. A reflective warning triangle placed behind the broken-down car alerts approaching traffic. High-visibility vests ensure both drivers remain visible when outside the vehicles. See our towing range and our breakdown safety guide. Additional items such as a steel tow pole or LED warning light can provide extra security on busy roads or in poor visibility conditions.

Tips for the towing driver

Take it slow and steady: the RAC advises never going above 15mph. Keep the rope taut and signal early. Avoid sudden braking or sharp turns that could snap the connection. Maintain gentle acceleration and check mirrors frequently for the towed vehicle. If the rope slackens, slow down gradually to retighten it without jerking. Never exceed the weight rating of your chosen rope or strap. Plan stops in advance and communicate clearly with the other driver using hand signals or mobile contact before the tow begins. Stay aware of changing road conditions and reduce speed further in wet weather or on bends.

Tips for the driver being towed

Stay alert and ready to brake if needed. Keep both hands on the wheel and maintain a safe distance. Never switch off the engine completely unless the vehicle is completely disabled. Apply the handbrake only when the tow has fully stopped. Communicate with the towing driver using agreed signals before starting. Keep the steering wheel straight and avoid over-correcting if the tow rope pulls to one side. Watch for any dashboard warning lights and be prepared to stop safely if issues arise during the tow.

When to seek professional help

If the tow distance is long or the vehicle has major damage, call for roadside assistance. Check your MOT and tax status free at CheckMOT before any journey. Professional recovery is often safer for complex breakdowns or when weather conditions are poor. Consider using a dedicated recovery service if either vehicle shows signs of further mechanical failure or if you lack the correct equipment for a safe tow.
