In some states, they have to display license plates, as well (for example, in Colorado, you have the Special Mobile Machinery - SMM - plates, although municipal/state equipment still uses the government - GVT - tags). No insurer is going to insure a minor, and any accident resulting from that minor operating that equipment is going to void the insurance policy. If it's a piece of rental equipment, the minimum age of the operator will be specified in the terms and conditions of the rental agreement.
