Chief Gilbert R. Carrel
Colorado State Patrol's second Chief, Gilbert R. Carrel was a member of the original Colorado State Courtesy Patrol. Chief Carrel was stationed in Denver during the first years of his Patrol career. In February 1936, he was promoted and transferred to Grand Junction as the Troop District Captain. In 1938, he was promoted and transferred back to Denver as the Deputy Chief under Chief Marsh.
Chief Carrel served during World War II, entering the military in a Seabee unit. During the Guam assault he was involved in the reconstruction of the facilities. While stationed in Guam, Marine officials had become alarmed at the high traffic death rate being amassed by the military personnel on the island of Guam. An average of ten military personnel were being killed each week on the island in traffic deaths. The military commanders had become aware of Chief Carrel's traffic experience. They transferred him into service with the Marine Corps, and gave him the job of coping with the traffic problem. Chief Carrel went to work signing the highways and training 400 MPs as traffic officers. When this operation went into action it took one month for the death rate to drop to zero. In cooperation with Teller Ammons, a former Colorado Governor who was an Army Major on the island, they wrote a traffic code based on Colorado's traffic laws.
