A very common driving mistake is landing some Brits a fine of up to £1,000 - but it's very easy to avoid.
A new survey from Comparethemarket has revealed that a massive 76 per cent of drivers - three in four - struggle with performing basic car maintenance tasks
Over one in five drivers (22 per cent) admitted they’re not confident when checking brake fluid levels, and this could prove costly, Somerset Live reports.
Not checking brake fluid levels correctly could result in a £1,000 fine and three penalty points.
Julie Daniels, motor insurance expert at Comparethemarket, said: “Our research suggests that more than one in five drivers do not feel confident conducting brake fluid level checks, this raises some safety concerns.
“In the colder months, brake fluid can thicken and congeal, which can compromise your braking power, causing them to become ineffective. Not only does this put the driver and passengers at risk but also the safety of other road users.
“According to The Highway Code, failing to have proper control of your vehicle could cost you £1,000 and three penalty points.”
Checking the brake fluid level was found to be the third most unnerving task for drivers, the research revealed, at 24 per cent.
Top of the list was changing a tyre with an estimated 11 million drivers admitting they would not feel confident closely followed by conducting an oil change.
It is essential brake fluid is topped up to ensure your car runs smoothly.
The Kwik Fit website says: "Seeing as brake fluid is such a vital component within your braking system, you should ideally check the levels every week.
"If you notice that the levels get low again pretty soon, you might have a leak - and you should book an appointment at your local garage as soon as you can.
"Brake fluid can deteriorate over time and absorb water content, which makes it much less effective. Most manufacturers recommend changing out your brake fluid altogether every 2 years. This part is a job for a mechanic!"
