Definitions; Injury accident: Any accident involving at least one road vehicle in motion on a public road or private road to which the public has right of access, resulting in at least one injured or killed person. Injury accidents exclude accidents incurring only material damage. Excluded are terrorist acts. Person killed: Any person killed immediately or dying within 30 days as a result of an injury accident. For countries that do not apply the threshold of 30 days, conversion coefficients are estimated so that comparisons on the basis of the 30 day-definition can be made. Person injured: Any person who as result of an injury accident was not killed immediately or not dying within 30 days, but sustained an injury, normally needing medical treatment. Persons with lesser wounds, such as minor cuts and bruises are not normally recorded as injured.
