Car insurance should be simple - paying out if you cause or are on the receiving end of damage on the road.
But you'd be surprised how many common incidents may not be covered.
Even the comprehensive policies offered by insurers can be very different and could leave you out of pocket.
Here, we highlight five areas of your cover which might not live up to your expectations.
But insurers are choosy about what counts as a 'personal belonging'. Only two of the 39 policies, for example, cover cash.
In 46% of the policies we analysed, mobile phones also weren't covered. Meanwhile, 18% of policies examined excluded laptops and tablets.
Only half of policies we scrutinised provide misfuelling cover as standard, while 36% don't offer misfuelling cover at all.
And a good chunk either only pay for draining the fuel from the tank (18% of policies), or just for repairing a damaged engine that's been run on the wrong fuel (18% of policies).
Just 28% of policies automatically cover both.
If your car is put out of action far from your home, car insurance usually covers the costs of getting you to your destination or back home.
Onward travel wasn't a feature of 26% policies in our survey, though, leaving your with a potentially pricey trip in a taxi.
Car owners with smashed sunroofs will - in 18% of policies looked at - find themselves unable to claim under the 'glass' section of their cover.
Glass cover is the part of the policy specifically related to the windscreen and windows, and it usually also includes sunroofs.
If it doesn't, you can claim instead under the policy's 'accidental damage' section - but at a cost that could reduce the value of claiming.
If you drop your keys down a drain, most policies will have you covered... to an extent.
Of the policies we scrutinised, 15% will pay for replacement keys and locks - but not for the locksmith's call-out charges.
Another 15% don't provide any cover at all for lost keys, instead only covering stolen keys.
We're guessing you probably don't - for most of us, price is paramount when picking insurance.
That said, the bills you could rack up by falling foul of these car insurance potholes could dwarf the cost of buying a better policy.
