Thursday night, Prescott Valley Police responded to a four-car collision at the intersection of Highway-69 and 169. Spokesman Jerry Ferguson says northbound traffic at Highway-169 was blocked for several hours. He says the driver of a Chevrolet Impala traveling northbound on Highway-69 approaching Highway-169 failed to see a red traffic signal and rammed into the rear of a Toyota Camry. This forced the Camry into two other vehicles. The occupants of the 3-rd and 4-th vehicles were not injured. All four vehicles were towed from the scene. Ferguson says the front passengers of both the Impala and Camry were airlifted to a Phoenix area hospital for non-life threatening injuries. The driver of the Impala was issued a citation for failing to control his speed to avoid a collision.
