Would you lend your car to a friend who isn’t insured to drive it? More than 5 million drivers would, according to research by Churchill.
The car insurance company warned that letting an uninsured driver use your car could land you with an average fine of £271 and three penalty points on your licence.
Many motorists assume their fully-comprehensive insurance cover lets them drive other cars third party, but that’s not always the case.
There’s often small print excluding under-25s from doing this – while some insurers ban it altogether.
The survey also found that 650,000 people have loaned their car to someone without checking if they’re covered by insurance.
If they weren’t, and were involved in a crash, the car’s owner could be left heavily out of pocket.
