If you've had your licence for any period of time, you'll surely be familiar with what's on the front of it. After all, this is what you'll have to show as a means of ID. However, even drivers who've been on the road for years are unlikely to have paid much attention to the reverse side of their licence. Look closely, however, and you may well notice certain numbers cropping up. These aren't random. In fact, they represent key information about you as a driver—and, in certain situations, ignoring them could land you with a hefty fine.

We're going to look at what these driving licence codes are, why they're so important and the repercussions you could face if you don't adhere to them.

What are driving licence codes?

You'll undoubtedly be familiar with the information that's listed on the front of your full driving licence—from your name to your address to the date your licence was issued. It's even got that #instaperfect picture of you on the front that somehow doesn't look as good in black and white. What you probably won't have glanced twice at, however, is the back of your licence.

Much like the front of your licence, the reverse side holds a range of important information that you should be aware of. If you turn it around, you'll be able to see a small table with numbered columns. Here's what each column represents:

  • Column 9 lists the type of vehicles that you might be entitled to drive
  • Column 10 shows the earliest date from which a driving category is valid from
  • Column 11 shows the date at which your driving category is no longer valid
  • Column 12 includes driving licence codes that show what restrictions are in place

The driving licence codes found in column 12 relate to certain rules or restrictions that are in place for the vehicle you drive and how your driving in general. These codes range from health-related conditions (needing to wear glasses or contact lenses) to stipulations for the vehicle you're driving (a limited number of seats or a maximum weight) to vehicle modifications (modified braking systems or clutch).

How does the DVLA know which codes I need on my licence?

Remember when you had to apply for your provisional licence? Part of your application involved you filling out a medical questionnaire and disclosing any medical conditions that could affect your driving. The DVLA uses this information—along with category-specific stipulations—to create the driving licence codes on the back of your card. If you declared, for example, that you need a hearing or communication aid, you'll have a 02 code on your licence. Your licence will even have a code if you told the DVLA that you're on the organ donor registry!

It's important that you keep your driving licence updated—whether it's a change in your medical condition(s), address or marital status. If you don't, the DVLA could fine you up to £1,000!

What if I just ignore my driving licence codes?

Though these driving licence codes might seem easy to ignore, it's important that you not only know which codes apply to you, but also that you adhere to the regulations they represent. If you're found to be violating these conditions, you could face serious consequences.

For starters, though roadside punishment is rare for driving licence codes, you could end up with a £100 on-the-spot fine by police for certain breaches, e.g., if you're not wearing glasses or contact lenses despite having a 01 code on your licence. You could also end up with 3 to 6 penalty points for “driving otherwise than in accordance with a licence” and an additional fine worth 50% of your weekly salary (capped at £1,000).

Even though the chances of you getting caught ignoring your driving licence codes are incredibly slim, do you really want to risk a fine or getting points on your licence? All you've got to do is glance at the back of your licence and see if there are any particular restrictions in place. It's not rocket science!
