“Mind the gap!” is a warning more often given to travellers on the London Underground than road users. But motorists are being warned to be on their guard against monster potholes – which are expected to litter UK roads over the next few months. Potholes traditionally appear on the road network in greater numbers between January and April each year. And this year looks set to deliver a bumper crop of the dangerous dents in the tarmac, which are made worse by the sort of wet weather and freezing temperatures the UK has endured of late, and which is forecast to continue. The Met Office reported that parts of southern England got around twice the average amount of rainfall normally expected in December. Not only does this mean more potholes, it also means more “invisible potholes”, which are harder to spot because they are filled with rainwater, and are particularly treacherous when you are driving in the dark. What’s more, any new potholes are unlikely to be filled in quickly as there are already some 200,000 in need of repair. All this is likely to lead to more pothole-related accidents, which have become increasingly common over the last few years as it is. Claims for cars damaged due to potholes have jumped 159% over the last three years, and 22% last year alone.
