HOW TO COMPLETE CHECKS ON MY TRAILER
Before every journey, it’s important to carry out a few simple checks on your trailer. These quick checks can help keep you safe, avoid breakdowns, and ensure your trailer is legal to tow.

01
Tyres
What to check:
-
Tyre pressure - Make sure tyres are inflated correctly. The tyre will show a maximum pressure on the sidewall for maximum load.
-
​Tread depth - Tyres have enough tread and are not worn down, you can use a tyre gauge to help with your checks. The minimum tread depth in the UK is 1.6mm but it is safer to replace your tyres before you reach this level.
-
General condition - Make sure there are no visible cracks, bulges or nails before you start your journey.
02
Tow Hitch and Coupling
What to check:
-
Hitch properly connect to vehicle - Lower the trailer onto the tow ball until it clicks into place.
-
​The locking mechanism is secure - it should be fully engaged and properly seated on the tow ball with no looseness.


03
Breakaway cable/Safety chain
What to check:
-
Attached to Vehicle - ​Make sure that this is correctly attached to the towing vehicle
-
Tow ball - Not wrapped around the tow ball (where possible)
04
Lights and Indicators
What to check:
-
Brake lights - Make sure the brake lights come on when you press the brake pedal
-
Indicators - Check all indicators are flashing correctly and in sync with your towing vehicle
-
Side/ Tail lights - Ensure all side and rear lights are working and clearly visible
-
Number plate light - Check the number plate light is working (if fitted) so your registration can be seen in low light
-
General operation – Walk around the trailer while the lights are on to confirm everything is working properly and there are no flickering or dim lights​​


05
Electrical Connection
What to check:
-
Plug connection - Make sure the plug is securely connected to your towing vehicle and fully pushed into place​​
-
Pins condition - Check there is no damage, dirt, or corrosion on the pins that could affect the connection
-
Cable position - Ensure the cable has enough slack for turning but is not dragging on the ground
-
General operation - Once connected, check that all lights are working correctly to confirm a proper electrical connection

06
Load Security
What to check:
Securing the load - Make sure your load is properly secured using straps so it cannot shift during travel
Weight placement - Spread the weight evenly to keep the trailer stable (where possible)
General Safety - Ensure nothing is overhanging or at risk of falling out during transit

07
Weight and Balance
What to check:
-
Trailer load - Check your maximum weight capacity and ensure your trailer is not loaded beyond the maximum weight limit
-
Weight distribution - Ensure the weight is evenly spread across the trailer to keep it stable while towing
-
Front-to-rear balance - Avoid placing too much weight at the rear, as this can cause instability and poor handling
-
General Safety - The trailer should sit level when connected to the towing vehicle, not tilting forwards or backwards
08
Wheel Nuts
What to check:
-
Tightness - Make sure all wheel nuts are tightened securely before starting your journey
-
General condition - Look for any signs of damage, rust or looseness around the wheel fixing points
-
Safety check - It’s good practice to recheck wheel nuts after the first few miles, especially after a wheel has been removed or replaced


09
Brakes (If fitted)
What to check:
-
Brake operation - Check that the trailer brakes are working correctly when you apply the brakes in your towing vehicle
-
Response - Make sure the brakes engage promptly and do not feel weak or delayed
-
General condition - If the trailer has not been used for a while or you notice anything unusual, have the braking system checked before towing
10
General Visual Checks
What to check:
-
Overall Condition - Walk around the trailer and check for any visible damage, loose parts, or anything out of place
-
Mudguards – Check mudguards are firmly in place and not damaged or loose
-
Signs of wear – Look for rust, corrosion, or worn components that may affect safety
-
General safety – If anything looks unusual or doesn’t seem right, have it checked before towing
