MILFORD, Mich. -

Police say the driver involved in a hayride accident over the weekend at Camp Dearborn had been drinking prior to the mishap. Milford Police Chief Tom Lindberg told Local 4 the driver of the tractor that was pulling the hayride had a blood alcohol level of .06 on a preliminary breath test - which is not admissible in court.

Police are still reviewing the case before they decide whether to turn it over to the prosecutor's office.

A camp supervisor told Local 4 that 18 people were on the ride when Sunday's accident happened and were thrown off when something went wrong. Most people were treated at the scene, but three were taken to the hospital.

The Ruth to the Rescue consumer unit did some checking and found there is no state agency charged with regulating hayrides. The issue came up in 2011 when there was an accident at Jenny's Dexter Market. In that case, a worker was injured, which brought the Michigan Occupational Safety and Health Administration into the case. However, there's no state agency that has jurisdiction over consumer safety issues, in regards to hayrides. Safety advocates have said hayrides often go unregulated because they are held on private property.
