The following is a publication from the DVSA (18th May 2022):
On the 18th May, the DVSA launched our new accredited training scheme for towing.
The new training scheme will provide motorists with the skills and knowledge they need to tow safely. The training covers large and small trailers – and courses are also available for drivers who want to tow specific types of trailers such as caravans and horseboxes.
Whilst we strongly recommend drivers get accredited training before they tow for the first time, the scheme is also available for people who already tow regularly. The training scheme can provide an opportunity to refresh and formalise their practical experience.
Encouraging your pupils to take accredited training
Some of your pupils may want to tow a trailer after they've passed their driving test. This could be to transport horses, or because they work in the agricultural industry.
Before they do this, they should get training with an accredited trainer. We know how important your advice and guidance is to your pupils, and we hope you'll encourage them to take this training before they tow.
