An automotive system for determining when safe lane changes may be made is provided. The system includes an automotive outside rearview mirror for mounting on a vehicle including a main viewing section and a blindzone viewing section. The main viewing section has a viewing angle such that when the entire front end of a following vehicle in an adjacent lane is visible near the outer edge of the main viewing section, the following vehicle is at a clearance distance behind the vehicle. The blindzone viewing section has a viewing angle approximately encompassing the region between the outer limit of the viewing angle of the main viewing section and the peripheral vision line of a driver looking at the outside rearview mirror. The clearance distance is judged to be a safe separation distance for changing into the adjacent lane in front of the following vehicle.
