Denver (AP) Children and teens on motorcycles will have to start wearing helmets under a new law that takes effect Sunday.
Violators will be subject to a $125 fine.
Forty-eight other states already require those 18 and under to wear helmets. Two previous attempts to add Colorado to the list in the 1990s failed.
Another law taking effect Sunday is one that will double the cost of specialty license plates to $50. Basic driver's license fees will also go up about five dollars to $20.40.
The extra money will pay to open three more motor vehicle offices in the metro area and hire 25 more workers for existing offices across the state.
