### Drivers Face £60 On‑The‑Spot Fine for Popular Car Modification, Experts Caution
Motorists across the UK have been cautioned by automotive experts following a surge in popularity for certain car modifications which, though trendy, could see drivers hit with fines on the spot. The warning comes as many vehicle owners seek to enhance their cars over the summer, often unaware of the strict regulations governing such changes.
One of the most common areas of concern highlighted by industry specialists is the fitting of tinted windows. Kazimieras Urbonas, supplier excellence manager at the car parts marketplace Ovoko, has spoken out about the potential pitfalls awaiting those who opt for heavily tinted windows, especially as temperatures rise and drivers look to keep their vehicles cool and shady.
Current UK law is clear on this matter: the front windscreen must allow at least 75% of external light to pass through, while front side windows must permit a minimum of 70% light transmission. Urbonas points out that failure to meet these standards could result in immediate penalties. “Drivers found to be breaching these rules risk being issued a ‘prohibition notice’ on the spot, meaning they cannot use the vehicle until the illegal modification is removed,” he stated. Offenders may also have to contend with a £60 fine and could see three penalty points added to their licence.
He advises that anyone considering tinted window installations should thoroughly check that the desired shade falls within legal limits and urges motorists to use reputable professionals for these upgrades. DIY attempts, he notes, are more likely to fall foul of the law, increasing the risk of fines, police intervention, or insurance issues. Importantly, for cars first registered before April 1985, the light transmission rules are slightly more lenient, but these regulations only apply to front windows; there are no legal restrictions on rear window tints.
Despite the clement image many associate with tinted windows—sleek looks and reduced sun glare—the safety risks must not be underestimated. Improperly darkened glass can severely hamper visibility, particularly in low-light conditions or at night, making it much harder for drivers to spot pedestrians, cyclists, or road signs.
Window tints aren’t the only car modification that have provoked official warnings. Excessively loud exhaust systems, for example, are also illegal if they push noise output over the accepted limit of 74 decibels for cars on the road post-1975. While some drivers modify their exhausts in the belief that a noisier car sounds more impressive or sporty, Urbonas cautions that police are increasingly attentive to such offences. Getting caught can lead to an immediate £50 fine and, in some cases, could see the vehicle taken off the road until the issue is addressed.
Further data underscores how often the law is breached inadvertently. Police records from 2020 show that well over 13,000 motorists were stopped for displaying illegal number plates. Rules here are again specific: number plates must use the Charles Wright 2001 font, be reflective, and feature specific background colours—white for the front, yellow for the rear. Deviations, such as using different fonts, adding colour tints, or including inappropriate language, can result in fines as high as £1,000, an instant MOT failure, or, in severe cases, even a driving ban or seizure of the vehicle.
Urbonas emphasises the importance of keeping thorough records of any modifications carried out. “Documents such as receipts are vital, especially if you need to make an insurance claim or during a police check,” he says. He also advises that even minor modifications should be reported to your insurer, as failing to disclose them could void your cover entirely.
Young and inexperienced drivers are particularly vulnerable, perhaps lured by trends such as neon under-car lights or headlight tints, both of which can cause visibility issues not just for themselves but also for other road users. Urbonas urges drivers to take a responsible approach, researching any intended changes in advance and only ever using certified installers.
Ultimately, the message from experts is clear: while customising your vehicle is certainly tempting, especially during the warmer months when car culture is at its most vibrant, safety and legality must always come first. By ensuring modifications meet official requirements, motorists will not only steer clear of costly penalties but will also contribute to safer British roads for all.
