UK Driving Licence Codes and Categories Defined : What You can Drive?


Though a driver’s licence is something that you’ll have along with you almost every single day, people don’t know much about this tiny little card. The categories at the back of your card may not be the most interesting thing to look at, but if you are curious, there’s a lot to know about them. The main reason behind people skipping out categories and codes other than the highway code is the difficulty and confusion that involves this topic. In this article, we have made an effort to simplify them for you, read on to know more. 

Standard UK Licence Categories 

These are the basic categories under which driving licences in the UK are divided.

The AM category 

Under this category, you can drive vehicles with 2 or 3 wheels with a design speed from 15.5 mph to 28 mph. Quad bikes that are about 350 kgs which do not run on electricity or batteries and have a speed of 15.5 mph to 28 mph are also included within the AM category. If you are looking to get this category licence, you’ll also need to clear the compulsory basic training test to start driving these vehicles. 

The B category 

This category is for driving cars, with a driver’s licence in category B, you can drive any car out there with up to 3500 kg mass and about 8 passenger seats. For everyone that’s over 21, you can also drive motor tricycles with more than 15kW power output. You can also drive motor tricycles that have an A1 or A requirement. 

The F category 

Most of the standard driver’s licences out there have an F category which basically enables you to legally drive any agricultural tractor. 

The K category 

With a K category licence, you are permitted to run any vehicle that needs you to walk behind it for controlling the vehicle. A good example of such a machine is a lawnmower. 

The Q category 

Under the category Q licence, you can legally drive any two-wheeler that has an engine size less than 50cc and a design speed less than 15.5 mph. 

Categories That you May Already Have

These are some of the categories that you may already have on your driver’s licence, take a look at the backside of your licence to know more.

For all of you folks that have passed the driver’s licence test prior to 1st January 1997, you can drive vehicles with trailers with an overall weight between 3,500 and 8,250 kg.

The category B auto is a category used instead of the B category that enables you to drive an automatic car but not a manual one.
