These plates are used on snowmobiles.
This type started in 1969. I’m not sure what number the series started at, but 3-digit plates are known for the earliest plates. Originally, all snowmobiles were supposed to be registered by October 1, 1969; however this was later changed to October 1, 1971. The fee at the time was $3, which was increased in 1975 to $4. Effective January 1, 2004 the fee is $20.
These plates were renewed every year until 1985, when they became biennial registrations.
These plates are similar in size, colors and format to Motorcycle plates.
Reference: Chapter 246 Sec. 14-380.
