The main causes of potholes are:
Potholes formed by cold weather are caused by the effect of a freeze followed by thaw. Over time, rain causes the road to become cracked and water can seep through the gaps in the surface which, when it gets cold will form ice. When the water turns into ice it expands and makes the gaps bigger, causing larger gaps and even holes that we see on our roads.
According to an Annual Local Authority Road Maintenance (ALARM) report, potholes cost British motorists an estimated £2.8 million in repairs, often through axle and suspension failure.
Potholes can cause instant damage to your car. Burst tyres and windscreen damage (which may not be covered by your insurance policy) can be both dangerous and expensive to repair. Damaged tyres can also add a huge amount on to a vehicle’s annual maintenance bill, so if you know there is a pothole in the road ahead, keep your speed down and try to avoid it without putting other road users at risk.
To report a pothole you can use fixmystreet or go through the official Government website. The authorities need to know that the road is damaged otherwise it won’t get fixed. Make sure they are aware of the potholes and that they are on the ‘to fix’ list.
If the pothole is on a major road, such as an A road or a motorway, you can contact the Highways Agency to investigate, on 0300 123 500.
Stay alert while you are driving and try to make a note of where the worst potholes are. Slowing down will also prevent severe damage to your car, as hitting a pothole at a slow speed will not affect your car as much as if you were to hit it at high speed. Keep your distance from the car in front of you while driving on a bumpy road.
If the damage occurs instantly and you need to pull over, do so quickly, calmly and safely. Check if anything has fallen off your car, it could pose a risk to traffic – if something has, either pick it up or alert the authorities. Don’t endanger yourself or other motorists if you decide to pick it up yourself.
Take notes of the damage and the circumstances in which your car sustained it. Record details of the pothole – where it is, how big it is, how deep it is and what shape it is. Take photos of it. Get phone numbers of any witnesses. To make a claim, you’ll need to produce the repair bill. Keep all receipts. If your claim is rejected by the council, you can consider the small claims court.
If you are finding it hard to avoid potholes that you drive over regularly, here are some key areas of damage which you should check before you set off.
The tyres are one area that may be heavily affected. Check that your tyres are inflated to the correct pressure and that the tread depth is at least 1.6mm in a band of at least ¾ of the tyre width. Driving with poorly maintained or damaged tyres could invalidate your insurance. Find out what advice the RAC give on tyre maintenance.
Cracks and chips may not be obvious but car wheels, although tough, can be dented by particularly hard jolts. If you hear rubbing noises whilst driving or notice feedback in the steering wheel, slow down or pull over and get your wheels checked by a professional at the earliest opportunity.
Cracks in windows, particularly windscreens, can be made much worse by bumps and jolts caused by potholes. These are usually easy to repair if caught early enough. So if you do see damage on your windscreen, get in touch with a professional repairer sooner rather than later.
Another area which can be damaged is the tracking. This system keeps both front wheels pointing in the same direction. The knock-on effect of damage to this system is reduced control of the vehicle, lower fuel efficiency and much faster and uneven tyre wear.
As fast as the authorities patch up the potholes, they seem to pop up elsewhere! So remember to be wary whilst driving, and that cutting your speed while on bad roads is going to be very beneficial and could end up saving you a huge maintenance bill.
