Motorists risk a fine of up to £1,000 and three penalty points for violating Highway Code Rule 97 and Annex 6. These rules require vehicles to stay roadworthy with clear visibility at all times, mandating that windscreens and windows remain clean and free from obstructions.
Key Requirements of Rule 97
Highway Code Rule 97 insists that drivers keep all glass surfaces free from dirt, condensation, frost, or internal items blocking the view. This aligns with the Road Vehicles (Construction and Use) Regulations, which demand full visibility through every window.
Even partial blockages heighten accident risks by slowing reaction times. Road safety research highlights poor visibility as a frequent factor in thousands of annual breakdowns and collisions across UK roads.
Additional Visibility Rules
Rule 229 reinforces this by requiring drivers to check all windows for clear sightlines before every trip. Faulty wipers, dirty mirrors, stickers, dashboard items, or hanging objects can lead to violations.
Penalties include fixed notices up to £1,000, with prosecution possible if visibility poses a serious danger. Dangerous driving conditions legislation may also apply.
Practical Tips to Stay Compliant
Drivers should verify wiper function, clean mirrors, and remove any sight-blocking clutter. Safety experts recommend stocking vehicles with de-icer, screen wash, and microfibre cloths year-round, especially in winter when frost and fog peak.
Winter under-preparation often causes preventable incidents. With millions of daily UK road trips, authorities urge pre-journey windscreen checks to avoid fines and ensure safety.
