Old motor vehicle laws


Did you know that automobiles used to be registered with the Secretary of State’s Office? In 1921, the registration fee was based on the A.L.A.M. (Association of Licensed Automobile Manufacturers) horsepower rating of the car. The fee was $5 for vehicles of 25 A.L.A.M. horsepower and under, $10 for vehicles between 25 and 40 horsepower, and $15 for vehicles of more than 40 horsepower. For comparison, according the Bureau of Labor Statistics Inflation Calculator, $15 dollars in 1921 has the buying power of $198.66 today.
