Top Tips: Keeping your car in a roadworthy condition.

Tyre Tread
It may not be part of your usual routine to check if your tyres have adequate tread, but it is very easy to do. 

Insert a 20p coin into the tread of your tyre, if you can’t see the outer rim of the 20p then your tyre is safe and has a minimum of 3mm tread depth.

If you can see the rim then your tyre has less than 3mm and you should get this checked as soon as reasonably possible.  You need to repeat this for each tyre.


For obvious reasons, it's incredibly important to ensure that all of your lights are in working order. Ensure that you check ALL of the following lights:

Dipped Lights

Full Beam

Reverse Lights

Brake Lights ​(Get somebody from your household to help you. If this is not possible, reverse up to a reflective surface such as a window or garage door to do this by yourself).

Hazard Lights

Engine Oil and Coolant
To do this you will need to open the bonnet. 

Remove the dipstick from the car, wipe it with a clean cloth and then insert the dipstick back into the tube. Remove the dipstick again, and check the oil level on the end of the dipstick. The oil should be between the minimum and maximum markers.

While you have the bonnet open, it is worthwhile checking the coolant level. Locate the coolant reservoir, it will have green,blue or orange liquid on. Check the markers on the side of the reservoir to see if the coolant level is between the minimum and maximum.

Working Brakes
When you are on your next essential trip, check whether the car sits straight when you press the brakes. If the car moves to one side then you should get your brakes checked by a professional.

Whilst driving, you should check if you can hear an audible squealing noise when you use your breaks. To hear clearly, you will need to turn the radio off. If you can hear a squealing noise, you should get your brakes checked by a professional as soon as possible.


It's also important to clean all of your windows to increase visibility when driving. It is also beneficial to clean your rear view mirror, wing mirrors, and window wipers.
