Certain types of accidents and damages require a police report in Oklahoma. Depending on the city where the accident occurs, a self-reporting system may be in place if there are no significant injuries to the vehicle's occupants or no major damage. If vehicle or property damages amount to $300 or more, the driver must report the accident in writing within six months from the date of the accident to the Oklahoma Department of Safety. Oklahoma law clearly states that if the driver of a vehicle causes an accident with serious injuries or death to occupants of an automobile, law enforcement should immediately be notified. It is best to dial 911. The attending officer will submit a police report.
