Maine, like most states, doesn't have strict regulations for hayrides, including the one that lurched down a steep hill and into a tree over the weekend, killing a 17-year-old girl and injuring more than 20 others.

Authorities say a mechanical problem caused a Jeep towing a wagon full of passengers in Mechanic Falls to crash during a Halloween-themed hayride in the woods Saturday. High school student Cassidy Charette was killed.

The state fire marshal's office says Maine doesn't have statutes that regulate hayrides. A program director with the National Conference of State Legislatures says Rhode Island is the only state that appears to explicitly require a permit to operate hayrides.

South Carolina and Texas laws mention the need for permits, but there's no clear administrative regulations regarding what's required.
