Motorists could face cumulative fines of up to £4,700 for breaking Highway Code visibility rules during sunny weather, according to motoring experts. As temperatures rise in the UK, drivers adapting their wardrobe for behind-the-wheel comfort may inadvertently breach regulations concerning sunglasses, headlight use, and windscreen condition.
Sunglasses and Headlight Rules
Under Highway Code Rule 94, drivers are cautioned against wearing tinted visors or sunglasses that impair vision, with a potential penalty of up to £100. Additionally, Rule 226 requires headlights to be used whenever visibility is reduced, not only after dark but also during intense sun glare. Breaching this rule can result in a fine of up to £1,000.
Clear View and Vehicle Control
Regulation 30 mandates that drivers maintain a clear and unobstructed view of the road at all times. Violations can attract a fine of up to £1,000. Experts also warn that failing to maintain proper control, such as not reducing speed in poor visibility like strong sun glare, could lead to a further £100 penalty. Driving with a cracked windscreen that obstructs the view under Regulation 30 could result in a fine of up to £2,500.
Windscreen Wipers and Roadworthiness
Keith Hawes, director of Nationwide Vehicle Contracts, highlighted that sun glare is an underestimated hazard. He advised keeping windscreens clean, wearing polarised sunglasses, and increasing following distance. The RAC also cautioned that faulty windscreen wipers could lead to a £2,500 fine under Regulation 34, which requires all vehicles to be roadworthy with fully operational equipment.
Motorists are urged to check their vehicles and adhere to Highway Code rules to avoid these substantial penalties during sunny spells.
