Category B+E training prepares a car driver to tow heavier trailers safely and legally, building the skills to couple, manoeuvre and reverse a car-and-trailer combination. It covers the practical handling of larger trailers — including those over the weight limits attached to a standard car licence — and ends in an assessment of competence rather than a sales pitch. The training exists because towing a loaded trailer changes how a vehicle accelerates, brakes, turns and reverses.
What B+E towing training covers
B+E is the licence category that lets you drive a car (Category B) while towing a trailer that exceeds the limits allowed under a standard car licence alone. Training is built around the skills needed to control that heavier combination from the first coupling to the final disconnection.
A typical course works through the full sequence of towing tasks. The aim is for the combination to feel predictable, even when it is fully loaded.
- Coupling and uncoupling — attaching the trailer to the towball, fitting the breakaway cable, connecting electrics and checking lights.
- Load and coupling safety — distributing weight correctly, checking the noseweight (the downward force the trailer puts on the towball) and confirming nothing is loose.
- Road driving — adjusting speed, braking distance and positioning to account for the extra length and mass behind you.
- Manoeuvring — controlled reversing into a defined space, plus turning and parking in tight conditions.
- Safety checks — tyre condition, trailer brakes where fitted, and a final walk-round before setting off.
The combination of a car and trailer behaves differently from a car on its own. The trailer pivots at the towball, so it swings the opposite way to the car when reversing, and it takes longer to stop. Training gives you time to learn these behaviours in a controlled setting.
Who needs a towing assessment
Category B+E training prepares a car driver to tow heavier trailers safely and legally, building the skills to couple, manoeuvre and reverse a car-and-trailer combination.
Whether you need B+E entitlement depends on when you passed your car test and on the weights involved. The rules changed in late 2021, so the starting point is to check what your existing licence already permits.
Drivers who passed a car test from 1 January 1997 onwards generally have entitlement to tow trailers up to a combined weight under current rules, while those who passed before that date often hold older grandfather rights. Anyone unsure should check the categories shown on the back of their photocard licence against the maximum authorised mass (MAM) — the maximum the vehicle and trailer are each rated to weigh when loaded — of the combination they intend to tow.
Even where formal B+E entitlement is not legally required, many people choose an assessment or training session before towing for the first time. Common reasons include:
- Towing a caravan, horsebox or large plant trailer for work or leisure.
- Moving up to a heavier trailer than you have handled before.
- Employers who require proof of competence for staff who tow.
- Wanting confidence with reversing and motorway towing before a long trip.
The key point is that legal entitlement and practical ability are separate things. You can hold the right licence category and still benefit from supervised practice, particularly with reversing and load safety.
Mastering trailer reversing
Reversing is the skill most new tow drivers find hardest, and it is usually the main focus of a session. The challenge is that the trailer steers in the opposite direction to what feels natural — turning the wheel one way sends the trailer the other.
Instruction normally breaks this down into small, repeatable steps. You learn to make gentle inputs, watch the trailer through the mirrors, and correct early before the angle becomes too sharp to recover. Over-steering is the most frequent mistake, and the fix is to move slowly and use small adjustments.
Practical reversing exercises tend to include:
- Reversing in a straight line and holding the trailer steady.
- Reversing around a curve into a marked bay or gateway.
- Recognising the point at which the trailer "jack-knifes" — folds too tightly against the car — and how to pull forward to straighten it.
- Using mirrors effectively, since you cannot rely on looking over your shoulder alone with a large trailer.
The reversing element matters beyond passing any assessment. Most real-world towing difficulties — reversing onto a driveway, into a pitch or up to a loading point — depend on the same controlled, low-speed technique.
How the training session is run
Training is usually delivered by an instructor in a suitable vehicle and trailer, either on a private manoeuvring area, public roads, or both. The structure varies between providers, but the general shape is consistent.
A session often begins with the off-road basics: checking the combination over, coupling up, and understanding noseweight and load distribution. Once that groundwork is in place, time moves to manoeuvring practice in a controlled space, then onto the road to cover speed, gaps, junctions and braking with the trailer behind you.
Towing training can be arranged as a one-off familiarisation, a short course, or a longer programme aimed at a formal B+E driving test where one is required. When booking, it is reasonable to ask a provider:
- Whether the vehicle and trailer match what you intend to tow.
- How much time is spent on reversing and manoeuvring.
- Whether the session leads to a test or assessment, and what that involves.
- What you need to bring, such as your licence and suitable footwear.
By the end of a well-structured session, a driver should be able to couple and uncouple safely, judge how a loaded trailer affects handling, and reverse with control. The goal is steady, confident towing in everyday situations rather than simply meeting a minimum standard.
