The number of hit-and-run accidents on Britain’s roads has increased, in part due to people thinking an incident not serious enough – or being unaware of the legal requirement – to report it or leave their details, according to research by insurers and criminologists. While the number of serious road accidents overall has declined, the percentage involving hit-and-runs is now at the highest level in more than a decade. The Motor Insurers’ Bureau handles 15,000 claims a year for victims of hit and runs. Ashton West, chief executive of MIB, said: “Hit-and-runs can have an everlasting impact on the victims and their families. We will be focusing on the recommendations that help raise awareness and educate drivers about their responsibilities.”Chris Grayling, the transport secretary, has in the past called for tougher penalties for hit-and-run incidents.
