Motorists are often bombarded with a plethora of advice, some accurate and some not so much, on how to safely navigate the roads. However, many common misconceptions can lead to unsafe practices or even legal issues.
From speed limits to drinking alcohol-free beer behind the wheel, it’s time to set the record straight. This is according to experts at The AA, who have sifted through the facts and fictions of driving, debunking 10 widespread driving myths and providing information 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 legally drive 10% over the speed limit. 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. Best advice: stick to the limit.
Drinking alcohol as a passenger in a car
It’s legal to drink alcohol as a passenger, but not always advisable. Passengers can aid safer driving.
If supervising a learner driver, you must stay sober and avoid using your phone. You absolutely can’t drink alcohol while driving, as even one drink could put you over the legal drink-driving limit.
Drinking alcohol-free beer while driving
While it’s not against the law to consume non-alcoholic beer while driving in the UK, if it looks like an alcoholic drink, you could still be pulled over by the police. To avoid any misunderstandings and delays, it’s advisable to save your drink until after your journey.
Sucking on a penny can trick a breathalyser test
This is not only false, it’s also illegal to try. Eating garlic, citrus fruits or mints won’t help either. The message is clear: don’t drink and drive.
Eating while driving
There’s no specific law prohibiting it, but if it distracts you, it could result in a charge of careless driving.
This carries a maximum penalty of £5,000, three to nine points on your licence and a discretionary driving ban. For safety reasons, it’s best to eat when stationary, particularly in adverse weather conditions when stopping distances are longer.
Smoking while driving
This is illegal in private vehicles carrying anyone under 18 or in company cars. If you occasionally use a private car for business purposes, smoking is permitted.
However, smoking can be a distraction and could potentially lead to a charge of careless driving.
Driving with snow on your car
While not illegal in the UK, the Highway Code stipulates that drivers must have clear visibility out of every window of their vehicle. If snow obstructs your view, this could be considered dangerous driving, which is certainly illegal.
It’s also advised to remove any snow from the roof as it can slide onto your windows or hit another road user.
Driving with interior lights on
There’s no specific law prohibiting this. However, it can cause distractions or impair vision at night and if it contributes to careless driving, you could face charges.
Circling a roundabout
Contrary to popular belief, circling a roundabout three times because you missed your exit isn’t illegal.
But it’s crucial to plan your route to avoid unnecessary circling, which could be viewed as careless driving. If you miss your exit, simply take it the next time after safely navigating around the roundabout again.
Lowering tyre pressures in winter
The idea that lowering tyre pressure during winter improves traction is a myth. In reality, it can increase stopping distances, cause more skidding, and reduce fuel efficiency. Instead, ensure your tyres are at the recommended pressure for safer winter driving.
An AA spokesperson said: “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.”
