There are no end of motoring myths. Most drivers will know at least a handful: sometimes they’re true, but often they’re stories that need to be shown the red light.
From the speed limit on a dual carriageway, to sounding a car’s horn in the small hours of the morning, driving in flip-flops to using an egg to repair an engine’s radiator, they can seem as confusing as the Spaghetti Junction.
To help sort the facts from fiction, we’ve pulled together 10 tricky questions for a motoring myths quiz. Which is driving delusion and which is as factual as the Highway Code?
#1. Fully comprehensive car insurance always covers you to drive any other car
It’s false! Never assume that a fully comprehensive car insurance policy covers you (third party) to drive any other car. Many policies don’t, especially for those under 25, so check with the provider.
#2. An egg can repair an engine’s leaking radiator
It’s true! In an emergency, drivers have been known to pour a raw egg into an engine’s radiator to patch up a leak. However, it’s a temporary fix at best. Professional products specifically designed for plugging a leak are available.
#3. You can leave an engine idling for as long as you like
It’s false! Rule 123 of the Highway Code says the engine must not be left running unnecessarily while a vehicle is stationary on a public road. If it is likely to be stationary for more than a couple of minutes, drivers should apply the handbrake and switch off the engine to reduce emissions and noise pollution.
#4. It is illegal to sound a car horn between 11.30pm and 7am
It’s true! Unless another road user poses a danger, the Highway Code says drivers can’t sound their car’s horn when driving in built-up areas between 11.30pm and 7am.
#5. The dual carriageway speed limit for cars is 60mph
It’s false! Have you been driving too slowly all this time? The national speed limit is 60mph on single carriageway roads but it’s 70mph on dual carriageways, unless otherwise indicated.
#6. The left lane of a motorway is the lorry lane
It’s false! All vehicles should use the left-hand lane on a motorway. Rule 264 of the Highway Code states: You should always drive in the left-hand lane when the road ahead is clear.
#7. It’s illegal to drive while wearing flip-flops
It’s false! There is no law against driving while wearing flip-flops, or when barefoot. However, it is not recommended.
#8. Having dirty number plates could lead to a fine
It’s true! Having a dirty number plate that is illegible could result in a fine of up to £1000. Drivers should ensure they keep both front and rear number plates clean – especially in winter weather.
#9. You can be penalised for driving too slowly
It’s true! If the police deem that you’re driving too slowly for the conditions and are causing a hazard, you could be prosecuted for the offence of careless driving.
#10. Big cars are always safer than small cars in an accident
It’s false! Crash tests of cars, carried out by independent safety organisation Euro NCAP, have shown that many small cars can be safer than larger models.
