Drivers are being warned they risk fines of up to £10,000 and 12 penalty points on their licence - and thus a road ban - unless they check their tyres are legally roadworthy with a simple 20p test.
A potential driving ban or a bank-breaking fine awaits motorists who fail to ensure their tyre tread depths are up to the minimum standard, motoring experts have warned.
According to the DVSA all four tyres must have at least 1.6mm of tread depth around the central three-quarters of the tyre breadth and across the entire outer circumference.
