A utility trailer hauling 20 children on a hayride Friday night lacked proper lighting and caused a rear-end collision that injured 11 of the revelers and an adult, State Police said on Saturday.

The children all had minor injuries but the adult, a man, suffered moderate injuries, Trooper 1st Class Jared Sandifer said in a news release.

The accident happened about 9 p.m. Friday on westbound La. 1024, also called Cane Market Road.

Ashley Posey, 37, Denham Springs, was pulling the trailer-load of children with a 2009 Honda ATV. Behind the trailer, Victoria Farr, 33, Denham Springs was driving a 2013 Mazda CX-5.

“As the ATV pulling the trailer traveled westbound (on Cane Market Road) the Mazda driven by Farr struck the rear of the trailer,” the release says.

The injured man, who was riding on the front utility rack of the ATV, was airlifted to Our Lady of the Lake Regional Medical Center. Sandifer did not release the man’s name. The children were taken to local hospitals.

State Police cited Posey for off-road vehicles; (lack of) authorization for use on the shoulders of certain public roads and highways and (no) tail lamps.

Troopers cited Farr for (no) safety belt and (no) child passenger restraint, the release say
