A Collision Risk Assessment System employs a plurality of sights located in front of and to the rear of a vehicle which may be an automobile, boat, plane etc. The sights may be in groups of three sights allowing the vehicle's operator to locate the center and the sides of the vehicle to the front and rear relative to the roadway, waterway, etc. The sights are laterally adjustable and are illuminated. The lateral adjustment permits the sights to be located as a function of the size of the vehicle's operator.
