British drivers could lose out on up to £114million in car insurance claims each year if they make simple mistakes like wearing the wrong shoes or failing to renew their road tax.
Uswitch research showed that two thirds of drivers studied could have future insurance claims rejected, or their policy cancelled entirely, thanks to tiny slip ups, The Mirror reported.
The company released a list of common mistakes, which revealed wearing flip flops was the easiest way to void your insurance.
The study found that a quarter of the motorists polled are guilty of wearing the summer footwear.
The report also found many motorists were unaware that items hanging from their windscreen or rear-view mirror that obstruct their view could invalidate their cover.
The survey of 1,593 consumers found the most forgetful drivers are dotted around Birmingham, where one in three people on the road routinely forget to lock their cars.
In Wales, 26 per cent of drivers also frequently forget to renew their MOTs on time.
Simple errors, which also involve forgetting to strap in your pet, could mean that British drivers lose out on £114million each year in unpaid claims based on an average claim amount of £2,671, according to Association of British Insurers’ (ABI) research.
A quarter of drivers admitted they did not realise these small errors could result in car insurance providers not paying out, with an additional third of drivers admitting they simply forget that such behaviours might impact on an insurance claim.
The latest data from the ABI shows that more than 43,000 car insurance claims are rejected a year.
Rod Jones, insurance expert at Uswitch.com , said: “We know the British public are increasingly time poor, so it’s unsurprising that motorists can be forgetful when it comes to locking up their cars or renewing their car MOT and taxes on time.
“With claims now running into the thousands of pounds, people can’t afford to make a careless mistake that could invalidate their cover and leave them out of pocket.
“It is therefore really important that drivers note down their key renewal dates and avoid making the easy to forget mistakes to ensure they are covered by should they ever need to make a claim.”
