For many drivers, the addition of a tow bar to their vehicle is a useful accessory. There are three main types of tow bars on the market - the self-aligning vehicle mount, the self-aligning receiver mount and the rigid a-frame mount. Each type of tow bar is suitable for different uses so it's important to ensure that you have had a proper think about what you plan to use the tow bar for and to make sure you purchase one that is suitable for your needs.
