Motorists risk fines up to £1,000 and three penalty points for violating Highway Code Rule 97, an often-overlooked regulation on vehicle windscreens and windows. This rule mandates that all vehicles remain roadworthy with clear, unobstructed visibility at all times.
Key Requirements of Rule 97 and Annex 6
Highway Code Rule 97, along with Annex 6, requires drivers to keep windscreens and windows clean and free from any obstructions. Supporting UK laws, such as the Road Vehicles (Construction and Use) Regulations, enforce full visibility through all glass surfaces.
Even minor blockages—from dirt buildup, condensation, frost, or interior items—can impair reaction times and elevate crash risks. RAC data shows hundreds of thousands of annual breakdowns and collisions on British roads, with poor visibility frequently contributing.
Additional Visibility Guidelines
Highway Code Rule 229 reinforces this by instructing drivers to verify clear views through all windows before every trip. The RAC also cautions that impaired vision may trigger penalties under dangerous vehicle condition laws.
Practical Precautions for Drivers
To comply, ensure wiper blades function properly, mirrors stay clean, and no stickers, dashboard items, or hanging objects block sightlines. Safety experts advise stocking vehicles with de-icer, screen wash, and microfibre cloths year-round, especially in winter when frost and fog peak.
The AA highlights poor preparation as a top cause of preventable winter driving mishaps.
Potential Penalties and Enforcement
Violations often lead to fixed penalty notices up to £1,000. Serious cases, where visibility poses clear dangers, may result in prosecution. With millions of daily road trips in Britain, authorities emphasize pre-journey windscreen checks to avoid hefty fines and ensure safety.
