Drivers in the UK face potential fines up to £1,000 for having dirty cars, as per Highway Code rules that require clear visibility. Experts emphasize that neglecting car cleanliness can lead to costly repairs due to micro-scratches and damage from corrosive contaminants. Additionally, maintaining a clean vehicle can improve fuel efficiency, potentially saving drivers £58 annually. With rising petrol prices over £1.50 per litre, motorists are encouraged to check tyre pressure and gear changes to enhance fuel economy and avoid hefty fines related to tyre maintenance. Scams involving fake QR codes on parking ticket machines have also emerged, prompting warnings from local councils. Drivers are advised to remain vigilant against such scams and ensure they pay through official channels.
