What Do the Codes on My Licence Mean?
Your UK driving licence may feature various driving licence codes, each with specific meanings that dictate the type of vehicles you are permitted to drive. The UK government has published these codes on its official website and these codes cover everything from eyesight requirements to vehicle adaptations, ensuring that drivers are suited for the vehicles they operate.

5. Trailer and Weight Limits
If you plan to tow a trailer, you’ll encounter several driving licence codes related to weight restrictions:
- 96 – Allowed to drive a vehicle and trailer where the trailer weighs at least 750kg, and the combined weight of the vehicle and trailer is between 3,500kg and 4,250kg.
