Your driving licence card contains lots of useful information, including your address, date of birth and the categories of vehicles you are permitted to drive. These are typed into 11 different numbered categories that span both sides of the card.
There's also a 12th column on the back of the licence with numbered codes on it. These codes are specific to each driver and signify a number of different things, including conditions for driving, such as needing to wear glasses, vehicle modifications that are required, plus restrictions, such as the licence holder only being allowed to drive a car with an automatic gearbox.
How does the DVLA know which codes to put on your licence?
When you apply for your provisional driving licence you are also required to complete a medical questionnaire that informs the DVLA if you have any specific requirements that need to be met in order for you to drive safely.
The two most common areas of concern are eyesight and hearing, and two of the licence codes relate to these: if you need to wear glasses code 01 will appear in section 12 of your licence, and if you need a hearing aid, 02 will be on your licence card.

If your hearing or eyesight deteriorates at any time, you are legally required to inform the DVLA so the relevant code can be added to your licence. Drivers with disabilities that could affect their ability to drive must complete an assessment at their local Mobility Centre where they have the opportunity to try out a range of vehicle modifications and adaptations that may help them while driving.
Driving licences expire after 10 years, and there is an opportunity for all drivers to update their health information when renewing their licence.
When you reach the age of 70, you must renew your licence every three years and complete a health declaration form each time.
What are driving licence codes, and what do they mean
The codes and their meanings are as follows:
Health-related codes
01 - eyesight correction, for example glasses or contact lenses
This denotes that you are legally required to wear corrective lenses, either contact lenses or glasses, when you drive.
02 - hearing/communication aid
The licence holder needs to wear a hearing aid while driving.

Vehicle modification codes
These are specific changes that need to be made to any vehicle to enable a disabled driver to drive it safely. They will be recommended for drivers after they have completed an assessment at their local Mobility Centre.
10 - modified transmission
The gearbox system needs to be altered so the driver can operate the car safely. A common adaptation is fitting a hand control lever onto a car’s gear stick.
15 - modified clutch
This code covers a number of clutch modifications for manual gearbox cars for disabled drivers who can’t press a conventional clutch pedal. They include the fitting of an automatic clutch system and a Duck Clutch, which enables the driver to operate the clutch via the gear lever with their left hand.

30 - combined braking and accelerator systems (for licences issued before 28 November 2016)
This code covers drivers whose licences were issued before 28 November 2016 and denotes that brake and accelerator system alterations are required for safe driving.

32 - combined service brake and accelerator systems
This code relates to systems that enable drivers to control the brake and accelerator with a hand, finger, knee, shoulder or limb. These adaptations can be suitable for drivers with limited strength or movement capabilities.
