In Minnesota, state law requires mechanical rides to be inspected once a year and the results sent to the Department of Labor and Industry. Ride owners are also required to do daily inspections and keep a log.
Fulfilling inspection responsibilities is put in the hands of the owner. The Minnesota legislature decided that it wanted the owners and operators and the insurance companies that insure these rides to be responsible for the safety of these rides.
Fairs may remove riders who do not follow rules.
184B.08 OPERATOR ENFORCEMENT.
A ride operator, owner, the State Agricultural Society, a sponsor, lessor, landowner, or other person who has contracted for the amusement ride to be offered to any riders may impose and enforce reasonable safety rules regarding the behavior of riders. An operator, owner, the State Agricultural Society, a sponsor, lessor, landowner, or other person who has contracted for the amusement ride to be offered to any riders, or its agents, may prohibit a person from riding a ride or may remove a rider from a ride for violations of those rules.
Inspector may be either an employee of the insurance company or an independent inspection service provider. Ride/device must be re-inspected after a major modification or serious illness/injury involving the ride. Owner/operator must report serious injury/illness arising from the use or operation of an amusement ride to either the state agency or local law enforcement. The accident must be investigated by the state or local law enforcement.
