The number of serious injuries caused by motor vehicles in British Columbia by month and year. This data includes only crashes attended by a police officer where the officer assesses that a victim will require more than 24 hours of hospitalization. This data excludes victims on roads where the Motor Vehicle Act does not apply (such as forest-service roads, industrial roads and private driveways); victims of off-road snow mobile accidents; homicides or suicides; and crashes where a police officer does not attend.
