Motor Vehicle Act of 1925 led to creation of the Highway Patrol
An increase in registrations (approximately 24,000 in 1920, and approximately 84,000 in 1929) led to the need for additional enforcement. Two inspectors were hired in 1920 to join Ara Griggs, and by 1929, there were twenty-two inspectors. They provided their own motorcycles, and their pay was $5/day with an additional 25 cents/day for insurance and $2/day for gas/oil. Most inspectors worked only from May 1st until Dec 1st. The Motor Vehicle Act of 1925 gave the inspectors increased enforcement and led to the creation of the Highway Patrol.
