IS A TOWBAR CHECKED DURING AN MOT?

If you’re a driver who frequently tows trailers, caravans, or horseboxes, you might be wondering: “Is a towbar checked during an MOT?” The short answer is yes — but there’s more to it than a simple yes or no. In this post, we’ll explain exactly what inspectors look for when it comes to towbars during an MOT, and how you can ensure your vehicle is compliant.

Why Are Towbars Inspected?

A towbar is considered a critical safety component. It affects the vehicle’s handling, braking, and the safety of other road users. Because of this, the MOT test includes a check of the towbar and its associated components to ensure they are securely fitted and in safe working condition.

What Gets Checked?

During an MOT, the following aspects of your towbar will be inspected:

Security and Condition

The tester will check whether the towbar is securely attached to the vehicle. They’ll look for any signs of:

• Corrosion or damage

• Loose bolts or fixings

• Cracks or structural weakness

  
  

Electrical Connections

If your towbar has a socket for trailer lights (most do), the MOT includes a check of the electrical connections. The tester will:

• Ensure the socket is securely fitted

• Check for damage or corrosion

• Test that the lights on a connected trailer would function correctly

Towbar Type and Fitment

The towbar must be:

• Type approved (for vehicles registered after August 1998)

• Fitted correctly as per manufacturer guidelines

Non-type-approved towbars on newer vehicles can result in a fail.

Will a Towbar Cause an MOT Failure?

Yes, it can — if it’s:

• In poor condition (e.g., rusted or cracked)

• Not securely mounted

• Incorrectly wired (e.g., trailer lights don’t work properly)

• Not type-approved on newer vehicles

Tips to Avoid MOT Towbar Fails

• Inspect it yourself regularly for rust, loose bolts, or frayed wiring.

• Use proper fitting: Always have towbars installed by professionals using type-approved kits.

• Test your trailer lights before taking your vehicle in for an MOT.

• Clean connections: Corrosion in the electrical socket is a common reason for failure.

Conclusion

Yes, your towbar is checked during an MOT — and for good reason. It’s essential for road safety. With a little attention and maintenance, you can ensure it won’t be the reason your vehicle fails its test.
