What are the reporting requirements if Ive been involved in a collision?
A traffic collision will be investigated by the Portland Police Bureau if one or more of the following criteria are met: • all fatal or potential fatal collisions • serious physical injury collisions • collisions involving operators who are under the influence of intoxicants • collisions involving drivers who fail to perform the duties required of them at traffic collision scenes (Hit and Run) • collisions involving hazardous material spills Collisions where no Police Officer was at the scene of the collision to investigate it, cannot later be investigated once the scene has been cleared and the driver’s have left. This does not apply to Hit and Runs.
