There is plenty of advice for motorists when it comes to learning how to navigate the roads safely. But some of this advice is not always accurate and there are many myths that have stood the test of time and continue to be shared. These misconceptions can lead to unsafe practices and even legal issues. Whether it’s about speed limits or alcohol-free beer behind the wheel, it’s time to put these myths to bed to ensure a safer driving environment for everyone.
To help, experts at The AA have separated driving fact from fiction debunking 10 widespread driving myths to help drivers stay safe and informed on the road.
Driving 10% over the speed limit without breaking the law
It’s a myth that you can drive 10% over the speed limit without breaking the law. While some police may allow for speedometer inaccuracies, enforcement varies. The National Police Chief’s Council suggests ticketing only when exceeding the limit by 10% plus 2mph (e.g driving 35 mph on a road with a 30 mph limit), but this isn’t guaranteed. So the best advice is to stick to the limit.
Drinking alcohol as a passenger in a car
Whilst it’s legal to drink alcohol as a passenger, it’s not always advisable, as passengers can aid safer driving. If supervising a learner driver, you must stay sober and avoid using your phone.
Drinking alcohol-free beer while driving
Whilst it may not be illegal to drink alcohol-free beer while driving in the UK, be warned, if it resembles an alcoholic beverage, you may still be stopped by police. To avoid confusion and delays, it’s best to wait until after your journey to drink.
Sucking a penny will fool a breathalyser
There’s a myth that sucking on pennies can cheat a breathalyser, not only is this false, it’s also illegal to attempt. Similarly, chewing garlic, citrus, or mints won’t work either. The message is simple: don’t drink and drive.
Eating while driving
There’s no specific law against eating while driving, but if it distracts you whilst you’re behind the wheel, it can lead to careless driving charges. This carries a maximum penalty of £5,000, three to nine points on your licence and a discretionary driving disqualification. To stay safe, the AA recommends to eat when stationary, especially in bad weather where stopping distances are longer.
Smoking while driving
It’s illegal to smoke in private vehicles with anyone under 18 or in company vehicles. If you use a private car for business occasionally, smoking is allowed. However, smoking can still be a distraction, potentially leading to a careless driving charge.
Driving with snow on your car
Whilst it’s not illegal to drive with snow on your car in the UK, the Highway Code states that you must be able to see out of every window on your vehicle. If snow on your windows is causing your visibility to be reduced then this could be deemed as dangerous driving, which definitely is illegal. You should clear any snow off the roof also, as this can slide over your windows and block your view, or fly off and hit another road user.
Driving with the interior lights on
Many believe it’s illegal to drive with interior lights on, but there’s no law against it. However, at night, it can cause distractions or impair vision, which may be deemed a factor in careless driving, meaning you could face a charge.
Driving around a roundabout three times
No, missing your exit on a roundabout isn’t illegal. However, it’s important to plan your route to avoid unnecessary circling, which could be seen as careless driving. Don’t worry if you miss it—just take it the next time after going back around the roundabout safely.
Having lower tyre pressure during winter
Lowering tyre pressure in winter for better traction is a myth. In fact, it can actually increase stopping distances, cause more skidding, and reduce fuel efficiency. Instead, ensure your tyres are at the recommended pressure for safer winter driving.
A spokesperson for The AA spoke about the importance of not being misled by common driving myths: “Many drivers unknowingly believe in these myths, which can lead to unsafe habits or even legal trouble. It’s essential to know the facts—whether it’s sticking to speed limits or avoiding distractions like eating while driving. Staying informed helps keep everyone safer on the road.”
