· Watch the weight of the towed vehicle – this should not exceed 85 per cent of the car’s kerb weight. Excess weight will cause instability.
· Check the unit you are towing is secure before pulling away, and check again after a short distance. Look for anything loose, disconnected, missing or broken.
· Check that your extra rear lights are all connected and fully functional. Get somebody to help while you test the brakes and indicators. As well as additional lights, you will also need an illuminated number plate at the rear of the unit.
· Check the pressure of all tyres before you set off, bearing in mind those of the towed unit as well as your own vehicle.
· Stopping distances and the space between you and other vehicles should be increased appropriately, allowing for the extra weight you are carrying. Allocate more time for overtaking, positioning yourself for turns, parking, pulling into traffic streams, changing lanes and joining and leaving motorways.
· Use your mirrors frequently. Drivers are obliged to be able to see traffic behind them, so the use of extended towing mirrors is encouraged for caravans and anything but a small trailer. Mirrors will also give you a better feel for overtaking and reversing.
· Be aware that reduced speed limits usually apply when towing vehicles, and remember to extend courtesy to vehicles following you by allowing them to pass.
