The Highway Code
A Common Set of Rules
Its main purpose is to help prevent road traffic incidents by ensuring that everyone follows a consistent set of rules when using the road.
Over time, road traffic law has developed into a detailed system of regulations — many supported by legislation.
In the Code, the words MUST or MUST NOT (shown in red) indicate that a specific legal requirement applies. The relevant law is cited beneath each rule.
Failing to obey these rules means you are committing a criminal offence. The Highway Code explains the law as simply as possible, to make it easy for everyone to understand and follow.
Keeping Up to Date
Road traffic laws and the penalties for breaking them change over time.
The Highway Code is updated regularly, so make sure you read and apply the latest edition.
Recent updates include new rules designed to improve safety for people walking, cycling, and riding horses.
Study these changes carefully and ensure you understand your responsibilities towards vulnerable road users.
Road Signs and Signals
You MUST know and obey:
-
All traffic signs and road markings
-
Signals given by traffic wardens, traffic officers, school crossing patrols, police officers, DVSA officials, and other authorised persons (such as road workers using ‘Stop/Go’ boards)
-

-
Junctions and crossroads

Road Safety
In everyday driving, always follow the rules set out in the Highway Code — for your safety and that of other road users.
Even experienced drivers must know the Code thoroughly and apply its principles every time they drive.
You MUST NOT drive:
-
Dangerously
-
Without due care and attention
-
Without reasonable consideration for other road users
While not all rules in the Highway Code are legal requirements, they may still be used in court to determine liability or support prosecutions under the Traffic Acts.
A Guide, Not a Restriction
Think of the Highway Code as an aid to safe and responsible driving, not as a limitation on your freedom.
