Will you give me the data on car accidents within the UK that are non alcohol or drug related? Please include fatal collisions, serious injury collisions, minor injury collisions and no injury collisions please.

We said

Thank you for your request. The requested information is not held by the Office for National Statistics. The best people to contact would be the Department for Transport.
