Drivers are being warned about a key Highway Code rule linked to the number 100. And there’s a potential criminal consequence for those who ignore it.
As unpredictable UK weather continues to catch motorists out, Rule 226 says drivers must use the correct lights when visibility drops. Breaking the rules isn’t just dangerous; it could even land you in jail.
It explains: “You MUST use headlights when visibility is seriously reduced, generally when you cannot see for more than 100 metres (328 feet). You may also use front or rear fog lights but you MUST switch them off when visibility improves.”
Drivers are also reminded of Rule 236 and to only use fog lights when visibility is very poor. Using them at the wrong time can dazzle other road users and make driving more dangerous.
It warns: “You MUST NOT use front or rear fog lights unless visibility is seriously reduced as they dazzle other road users and can obscure your brake lights. You MUST switch them off when visibility improves.”
These rules apply to all drivers. GOV.UK stresses that “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.
“Such rules are identified by the use of the words ‘MUST/MUST NOT’. In addition, the rule includes an abbreviated reference to the legislation which creates the offence.”
