Government 'prison' warning over failure to follow HIghway Code rules

Although some rulings under the Highway Code may seem extreme to many, the government warn they are legal requirements and failure to follow them could see drivers sent to prison.

They say: “Many of the rules in the Code are legal requirements, and if you disobey these rules you are committing a criminal offence.

“You may be fined, given penalty points on your licence or be disqualified from driving. In the most serious cases you may be sent to prison.”

Highway Code rules are not laws, however many rules included to cross over into legal requirements, so it is important that you follow the guidelines.
