Crashes have to be recorded by police to help determine who was at fault, and so that authorities can analyse causes and decide on solutions. Various forms are used to code the crashes. Every country has different methods, some involving coded diagrams and others, like in the UK, that are a lot of checkboxes and written descriptions. Members of the public can even get crash coding forms from police branches such as the Met<\/a>.<\/p>\n

But a real police coding form is a complex beast with a large number of sections to fill out, and it’s worth highlighting them so that you can see what factors police believe contribute to a crash.<\/p>\n
