IAM Fleet and Drive & Survive have issued advice on how to deal with potholes estimated to cost motorists £320 million every year.

Simon Elstow, head of training said: “Potholes form and get worse after icy spells as water gets into small cracks in the roads, expanding as it freezes and forcing the tarmac apart. For this reason, roads will increasingly start to show signs of damage as the weather warms up.

“As well as worrying about your vehicle, with potholes being a major cause of suspension failure, business drivers should be particularly conscious of cyclists and motorcyclists trying to get past a pothole and give them a wide berth."

More pothole advice from IAM Fleet and Drive & Survive:

• Leave plenty of room between you and the vehicle in front so that you can see the road surface before you drive or ride on it
• If you do hit a pothole accidentally, make a point of checking your tyres once you’ve stopped. Check the inner as well as the outer tyre wall, which may have been damaged as a result
• Avoid suddenly pulling out to avoid a hole – you might discover that there is a motorcyclist trying to get past you, or encounter an oncoming vehicle
• Bikers and cyclists need to look well ahead and change direction early so they have time to deal with the holes, and so that their movements don’t cause surprise to other road users
• Potholes tend to reappear in the same place again and again as previous repairs fail - remember where you saw one and expect it to be there again
• Be extra vigilant on roads with lots of lorries and also around bus stops. Extra pressure is put on the road surface wherever heavy vehicles stop, start or turn
