Meta description: Discover common towing mistakes in Scotland and how B+E trailer training can help you tow safely around Glasgow, Lanarkshire and Renfrewshire.
Hello there! Towing can open up all sorts of possibilities. Perhaps you’re heading to a campsite near Loch Lomond, taking a horsebox to an event, collecting materials with a work trailer or moving house with a box trailer.
But towing isn’t simply a case of attaching something to the back of your car and setting off. The trailer changes how your vehicle accelerates, brakes, turns and reverses. Even familiar roads around Glasgow can feel very different when you’ve got several extra metres following behind you!
At Allison Driver Academy, we provide practical B+E trailer training for drivers across Glasgow, Lanarkshire and Renfrewshire. In this guide, I’ll look at the most common towing mistakes we see and explain how structured training can help you replace them with safe, repeatable habits.
1. Getting the coupling and breakaway cable wrong
One of the most serious towing mistakes happens before the vehicle even moves.
Drivers sometimes lower the trailer coupling onto the tow ball without checking that it’s fully seated and locked. Others forget to insert a locking pin, leave the jockey wheel partly lowered or connect the electrics incorrectly.
The breakaway cable is another common source of confusion. It shouldn’t just be looped over any convenient part of the tow bar. It needs to be attached correctly according to the vehicle and trailer instructions, ideally to the designated attachment point where fitted.
Before every journey, you should check:
- The coupling head is fully engaged with the tow ball.
- The locking mechanism shows that it’s secure.
- The locking pin is fitted where required.
- The breakaway cable is correctly attached.
- The jockey wheel is raised, secured and clear of the road.
- The electrical connection is plugged in properly.
- The trailer lights and indicators are working.

How B+E training fixes this habit
During training, we teach coupling and uncoupling as a clear sequence rather than a rushed last-minute job. You’ll practise the checks until they become automatic.
That matters because busy locations can be distracting. You might be at a campsite with people walking around, at a yard with machinery moving or outside a supplier in Lanarkshire while you’re keen to get home. A set routine helps you slow down and check properly every time.
2. Overloading or loading the trailer badly
A trailer can be within its legal weight limit and still be loaded poorly.
Common mistakes include putting heavy items at the very rear, loading everything on one side or placing tall, heavy objects high up. This can affect the trailer’s stability and make it more likely to sway or snake.
For example, a work trailer loaded with heavy tools at the back may look fine when parked. Once you reach an exposed road, a wet bend or a faster section of the M8, that poor weight distribution can become a real handling problem.
Try to:
- Check the trailer’s Maximum Authorised Mass and the towing vehicle’s limits.
- Keep heavier items low down.
- Position weight as close to the axle as practical.
- Spread the load evenly from side to side.
- Secure equipment so it can’t slide, roll or fall.
- Follow the manufacturer’s noseweight guidance.
Never guess the weight of a trailer or its contents. Check the vehicle handbook, trailer plate and relevant manufacturer information. The official GOV.UK towing guidance is also worth reading before you tow.

3. Panicking when the trailer starts to sway
Trailer sway can be frightening, especially if you’re travelling on an exposed road and a gust of wind arrives just as a lorry passes.
It can be caused by poor loading, excessive speed, crosswinds, uneven road surfaces or sudden steering and braking. The wrong reaction is often to make a sharp steering correction, accelerate hard or stamp on the brakes.
If the trailer begins to move from side to side:
- Stay calm and keep your steering smooth.
- Ease off the accelerator gently.
- Avoid sudden braking or steering.
- Allow the outfit to slow in a controlled way.
- Stop somewhere safe if you need to inspect the load or take a break.
A trainer can help you understand how speed, load position and steering inputs affect stability. You’ll also learn how to spot the early signs of trouble rather than waiting until the trailer is moving dramatically.
4. Reversing too quickly or overcorrecting
Reversing a trailer is probably the mistake drivers worry about most. The trailer moves in the opposite direction to the rear of the car when you turn the steering wheel, and that can feel completely unnatural at first.
A common error is turning too much, too quickly. The trailer then swings sharply, the driver panics and the whole combination ends up at an awkward angle. Cue a tense silence, a very concerned passenger and possibly a request to “just have a go” from someone who hasn’t volunteered to help!
The safer approach is to:
- Check the area carefully before you start.
- Use both towing mirrors.
- Reverse at walking pace.
- Make small steering inputs.
- Pause regularly to reassess.
- Pull forward and reset when necessary.
- Ask a competent person to guide you where visibility is limited.
There’s no prize for reversing in one heroic movement. Safe, controlled progress is what matters.
How structured training helps
The DVSA car and trailer training syllabus includes reversing, coupling, uncoupling, safe loading and on-road driving. Good B+E training brings these skills together in a calm, practical way.
You’ll practise in a suitable area before progressing to situations that feel more realistic, such as reversing into a bay, positioning a trailer at a campsite or manoeuvring in a tight yard.
5. Forgetting trailer cut-in on bends
When you drive your car around a corner, the rear wheels follow a tighter line than the front wheels. With a trailer attached, the trailer wheels can cut in even further.
This is easy to forget on narrow country lanes or when turning into a side road. You may clear the corner with the car but allow the trailer to clip the kerb, a bollard or even another vehicle.
You need to think about the full length and width of the outfit:
- Approach bends at a sensible speed.
- Look well ahead and plan your position early.
- Allow extra room for the trailer wheels.
- Check your left mirror carefully when turning left.
- Avoid swinging out more than necessary when turning right.
- Take extra care at roundabouts and tight junctions.
Around Glasgow, you may need to manage several lanes and busy traffic at once. On country roads in Renfrewshire or Lanarkshire, the challenge may be a narrow bend with a stone wall on one side. Training helps you adapt your positioning to the road rather than relying on one rigid technique.
6. Ignoring blind spots and using mirrors poorly
A trailer can block your normal rear view, while a wide caravan, horsebox or plant trailer can create significant blind spots.
Some drivers attach towing mirrors but don’t adjust them correctly. Others only check one mirror before changing lanes. That’s risky on roads such as the M77 or M8, where traffic can approach quickly from behind.
Before setting off, adjust your mirrors so you can see:
- Both sides of the trailer.
- The lanes alongside you.
- Traffic approaching from behind.
- The trailer wheels and body where possible.
Use your mirrors regularly, not just when changing lanes. They’re especially important when cornering, merging, overtaking or reversing.
During B+E training, we’ll help you develop a proper observation routine. You’ll learn to combine mirror checks with timely signals, sensible speed and good forward planning.
Why B+E training matters when the separate test isn’t required
The rules changed in December 2021. For most drivers with a full Category B licence, a separate car-and-trailer practical test is no longer required to tow a trailer within the relevant legal limits.
That doesn’t mean training is unnecessary.
Your licence tells you what you’re legally allowed to tow. It doesn’t automatically teach you:
- How to couple a trailer safely.
- How to check the breakaway cable.
- How to distribute a load.
- How to prevent or manage sway.
- How to reverse around a corner.
- How much space to allow for cut-in.
- How to use towing mirrors properly.
- How the outfit behaves on hills, bends and faster roads.
The DVSA describes car-and-trailer training as a way to improve driving competence, and that’s exactly the point. Professional tuition can give you practical experience before you’re towing your own caravan, horsebox or work trailer with family, equipment or animals on board.
Choosing the right trainer in the West of Scotland
Allison Driver Academy operates with both fully qualified instructors and trainee instructors, also known as PDIs, across Glasgow, Lanarkshire and Renfrewshire.
A PDI is training towards becoming a fully qualified DVSA Approved Driving Instructor. However, someone training as a car driving instructor isn’t automatically qualified to deliver B+E tuition. B+E training should be delivered by a trainer with the appropriate towing qualifications, experience and vehicle combination.
When you contact us, we’ll help direct you to the right trainer for your needs. Our wider services include learner lessons, ADI training for people who want to become a driving instructor, and fleet driver assessments for businesses managing towing and wider road risk.
If you’re comparing driving lessons glasgow, manual driving lessons glasgow or automatic driving lessons glasgow, local knowledge and a calm teaching style matter. The same applies when choosing a driving school Lanarkshire or a driving school Renfrewshire for trailer tuition.
A safer towing routine starts here
The best way to avoid towing mistakes is to build good habits before you need them. Check the coupling. Inspect the trailer. Load it carefully. Adjust your mirrors. Plan for extra length, width and stopping distance. Then practise until the process feels natural.
