Motorists are often bombarded with a mix of accurate and misleading advice on how to safely navigate the roads. Unfortunately, these common misconceptions can lead to unsafe driving habits or even legal complications.

From misunderstandings about speed limits to the legality of consuming non-alcoholic beer while driving, it’s high time we cleared up these misconceptions.

This is according to experts at The AA, who have taken it upon themselves to separate fact from fiction, debunking 10 prevalent driving myths. Their aim is to provide drivers with accurate information to ensure they remain safe and informed on the road.

The AA experts tackle 10 popular driving myths

Driving 10% over the speed limit without breaking the law

Contrary to popular belief, it’s not legal to drive 10% over the speed limit. While some police officers may allow for speedometer inaccuracies, enforcement varies.

The National Police Chief’s Council suggests only issuing tickets when drivers exceed the limit by 10% plus 2mph (for example, driving at 35 mph in a 30 mph zone), but this isn’t a guarantee. The best advice is to stick to the limit.

Drinking alcohol as a passenger in a car

While it’s legal to consume alcohol as a passenger, it’s not always the wisest choice. Passengers can contribute to safer driving.

If you’re supervising a learner driver, it’s crucial to stay sober and avoid using your phone. It goes without saying that drinking alcohol while driving is strictly prohibited, 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, you could still be pulled over by the police if it looks like an alcoholic drink. To avoid any misunderstandings or delays, it’s advisable to save your drink for after your journey.

Sucking a penny will fool a breathalyser

There’s a common myth that sucking on a penny can trick a breathalyser test, but this is both untrue and illegal to attempt. Other supposed tricks like chewing garlic, citrus, or mints won’t work either. The message is clear: don’t drink and drive.

Eating while driving

As for eating while driving, there’s no specific law prohibiting it. However, if it distracts you and affects your driving, you could face charges of careless driving.

This offence 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 where stopping distances are longer.

Smoking while driving

Smoking while driving is illegal in private vehicles carrying anyone under 18 or in company vehicles. If you occasionally use a private car for business purposes, smoking is permitted.

Nonetheless, smoking can be a distraction and potentially lead to a charge of careless driving.

Driving with snow on your car

While there’s no law against driving with snow on your car in the UK, the Highway Code stipulates that drivers must have clear visibility out of every window. If snow obstructs your view, it could be considered dangerous driving, which is indeed illegal.

It’s also advisable to remove snow from the roof as it can slide onto your windows or hit another vehicle.

Driving with the interior lights on

Contrary to popular belief, there’s no law prohibiting driving with interior lights on. However, it can cause distractions or impair vision at night and if it contributes to careless driving, you could face charges.

Driving around a roundabout three times

Missing your exit on a roundabout isn’t illegal either, but unnecessary circling could be viewed as careless driving. If you miss your exit, simply go around the roundabout safely and take it the next time.

Having lower tyre pressure during 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.

For safer winter driving, ensure your tyres are at the recommended pressure.

According to a spokesperson for The AA: “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.”
