Most towing problems don’t happen on the road — they happen because of what wasn’t checked before leaving. A loose strap, a flat tyre, or a faulty light can turn a simple journey into a breakdown, delay, or even a fine.
The good news? A quick 5-minute pre-tow routine can prevent the vast majority of towing issues. This guide gives you a simple, reliable checklist used by professional operators — adapted for everyday trailer owners.
Why a Pre-Tow Check Matters
Whether you tow once a month or every day, towing your own trailer, or a trailer you hired – remain the same. Trailers are classed as road-going vehicles, meaning you must ensure they’re safe, roadworthy and legally compliant before you start towing.
For commercial operators, daily walkaround checks are a legal requirement. Private users aren’t legally mandated to perform them — but the risks are identical:
- Faulty lights can lead to roadside stops or penalties
- Under-inflated tyres cause blowouts
- Loose couplings or breakaway cables can lead to serious accidents
- Poorly secured loads can shift, damage the vehicle, or fall onto the road
A five-minute inspection can save you hours of hassle — and potentially expensive repairs. Treat it as your pre-flight check every time you tow.
Your 5-Minute Pre-Tow Checklist
Use this list before every journey, no matter how short. Each point includes a brief explanation so you know exactly what to look for.
Lights & indicators
- Test brake lights, indicators, hazards and side lights.
- Ask someone to help or use reflections from nearby windows or walls.
Tyre pressure & tread
- Trailer tyres degrade faster than car tyres and often sit unused for long periods.
- Check pressure, tread depth and look for cracks or bulges in the sidewalls.
Coupling & hitch
- Ensure the coupling head is fully latched onto the tow ball.
- Lift the jockey wheel slightly to confirm the hitch is locked in place.
Breakaway cable
- Attach it securely to the tow vehicle, not the tow ball.
- Make sure the cable isn’t dragging and has a clean, unobstructed path.
Load security
- Check straps are tight, correctly rated and not frayed.
- Load should be balanced with weight slightly forward of the axle.
Brakes (if applicable)
- On braked trailers, visually check brake cable tension and overrun device movement.
Number plate & lights board
- Trailer must display the same registration as the tow vehicle.
- Make sure it’s clean, visible and the lights board is firmly attached.
Jockey wheel & stand
- Fully raise, lock and secure.
- Ensure stabilising legs or stands are folded away and pinned correctly.
This checklist covers the most common causes of towing failures — if everything here is correct, you’re already far safer and more compliant than most road users.
Optional but Recommended Extras
If you want to make towing even smoother, consider adding these quick habits:
- Keep gloves, a torch and a high-vis vest in your tow vehicle for night checks or emergencies.
- Carry spare bulbs and 7-pin/13-pin adaptors in case something stops working.
- Give lights and reflectors a fast wipe-down if they’re dusty or muddy.
- Carry a wheel chock for safer loading and unloading.
- Store a spare strap or tie-down for unexpected load adjustments.
If you need replacements or upgrades, contact us for any spare parts – we stock bulbs, adaptors, straps, breakaway cables, reflectors and anything else you might need.
Build It Into Your Routine
The best pre-tow checklist is the one you actually use. Here are simple ways to make the routine automatic:
- Print the checklist and keep it in your glovebox
- Add it as a note or shortcut on your phone
- Create a habit trigger, such as checking everything while warming the engine
- Do checks in the same order every time — repetition builds confidence
- Include it in your loading process so nothing gets forgotten in a rush
Just like commercial operators, treating pre-tow checks as a non-negotiable routine keeps you safe, legal and prepared for every journey.
If your trailer fails any check or something doesn’t feel right, booking a quick inspection through our Trailer Servicing page can prevent problems getting worse.
