Tow bars come in many different shapes and sizes, and which one you should buy will depend entirely on your towing needs.

When it comes to being adjustable, it is often not the tow bars themselves but the brackets which are adjustable.

In most European countries, the speed limits will differ to the ones marked on the roads if you are towing a trailer or a caravan. For safety reasons, vehicles which have items in tow are not allowed to travel as fast as other vehicles on the roads.

This may seem to be a fairly obvious standard practice, but it is not always clear exactly what the rules are. To make it easier for drivers travelling with trailers and caravans in tow on the continent, we have compiled a list of the maximum speed which you can travel on a motorway if you are towing in Europe. The speed limits will differ on other types of roads.

Trailer connectors are used to link the electrical systems of the vehicle to those of the trailer or caravan. This is how the trailer or caravan can display the corresponding lights if you use the indicators, turn on the tail lights, use the brakes or fog lights. This is extremely important for the safety of your driving whilst towing.

If those behind you cannot see the signals you are giving them, this could, in extreme circumstances, lead to serious accidents. It is therefore important to make sure that you have the right fittings and connectors before you set off on a journey with a trailer or a caravan in tow.
