When it comes to choosing the right trailer, whether you need to transport bulk materials for a small business, tow a horsebox or require a trailer to fit a typical car for additional carrying capacity, there are a range of factors to consider.
Beyond the trailers themselves, of which we have an extensive selection manufactured by Ifor Williams and your particular needs, one essential factor to keep in mind is ensuring you are legally able to tow a particular trailer.
This can be somewhat complex, as the law surrounding towing trailers varies depending on when you passed your driving test, the type of car you are using and the overall combinations of weight classifications for both the car and trailer.
What Can You Tow With A Standard Car License?
There are a lot of different types of vehicle categories that can be part of your driver’s license, and passing your driving test gives you access to several of these that you can legally drive without additional training.
Typically, anyone who has passed their driving test will have the ability to drive cars that have a Maximum Authorised Mass (MAM) or Gross Vehicle Weight (GVW) of up to 3,500kg.
This is roughly the weight of a Range Rover or a Ford Transit van and includes the weight of the car itself and how much it can legally carry inside or securely on top of it.
A car driving license is officially known as a category B license and allows you to also tow a trailer up to the maximum rated weight of the vehicle itself, which is officially known as category BE.
Where it becomes confusing is that the exact towing limits vary depending on when you passed your driving test.
Why Are The Weight Limits Different?
If you passed your test before New Year’s Day 1997, you can tow a vehicle and trailer combination up to 8,250kg in most cases, with varying combinations allowed for heavier cars and lighter towing vehicles.
However, a modern driving license separates the car and trailer weights, so you are allowed to drive any vehicle with up to eight seats that weighs up to 3,500kg, and tow a trailer that weighs up to the same, for a total towing capacity of 7,000kg.
This has changed since 2021, when the limit was just 750kg unless you took the additional B+E test.
The reason why this is different is largely the result of the grandfather clause; to avoid disruption to businesses, sole traders and minibus drivers who relied on the original weight limits as written, anyone who passed their test before 1997 could still use the old regulations and clauses for as long as they could use their license.
What Happens If You Need A Bigger Trailer?
For the most part, our horseboxes, trailers, and even our larger Transporta have a gross weight on or under the limit, so the standard limit provides a lot of options, as long as you have a vehicle which has the required towing capacity.
However, if you need either a larger towing vehicle or require a specialised vehicle, you can apply to upgrade your license to increase the capacity of the vehicle you can legally drive.
There was previously a trailer MAM limit of 750 kg on a category BE license unless you took an additional test for a B+E license, but whilst that requirement has been removed, there are still several schemes, such as the Safe Towing Scheme, that will train drivers to tow safely.
However, if you need a substantially bigger trailer or need to use a heavier vehicle, then you can apply for a Category C1+E license, which will allow you to drive any vehicle up to 7,500kg, which would be the size of a medium-sized box van, and any trailer as long as the combination is no heavier than 12,000kg.
If you need any more than this, such as to tow our StockMaster trailer, you will need a category CE license.
Are There Any Other Limitations Surrounding Trailers?
Almost all of our range of trailers that we supply are specifically designed to keep within the 3,500kg MAM limit to give you peace of mind; as long as you have the right towing vehicle and a full driving license, you can use any of our trailers.
We also keep within the width and length limits for trailers with the vast majority of the trailers we supply, so they are no wider than 2.55 metres and no longer than seven metres.
