As the UK experiences rising temperatures, motorists are advised to be cautious about adhering to the Highway Code to avoid hefty fines. Experts indicate that drivers could face penalties totaling up to £4,700 for infractions related to visibility. For instance, wearing sunglasses that obstruct vision can lead to fines of up to £100, while failing to use headlights during bright sunlight may incur penalties of up to £1,000. Additionally, drivers must maintain a clear view of the road; violations can result in fines of up to £1,000. A cracked windscreen that obstructs the driver's view could lead to a severe penalty of up to £2,500. Keith Hawes, director of Nationwide Vehicle Contracts, warns that sun glare is often underestimated, significantly impairing visibility and reaction times, especially during sunrise and sunset. He advises drivers to keep their windscreens clean, wear polarized sunglasses, and maintain a safe following distance to enhance road safety. Furthermore, the RAC has highlighted that non-functional windscreen wipers could also result in fines of up to £2,500, reminding drivers of the importance of vehicle maintenance.
