Driving licence categories and codes
Working out what the driving licence codes and categories mean can be confusing. Here’s an explanation of some of the most common.
Driving licence categories and codes will usually explain what vehicles you can drive, and what conditions you must meet to drive your vehicle. They can usually be found on the back of your driving licence.
Why does my driving licence have codes and categories on it?
Each category of vehicle is represented by a letter or a letter and a number. These show which vehicles you’re qualified to drive.
Some vehicles you’ll be eligible to drive just by passing your standard driving test, others require specific instruction.
Driving licence codes are slightly different. They display what conditions you must meet to drive your car. For example, your driving licence will display a certain code if you need glasses or contact lenses to drive.
Other codes include whether you’re an organ donor or if your car needs certain modifications.
