Officials say alcohol and speed appear to be โ€œprimary contributing factorsโ€ when an ATV crashed on Stark Pond Trail in Dunbarton Monday evening, injuring both driver and rider.

On July 28 at approximately 6:45 p.m., New Hampshire Fish and Game was notified of the crash involving a male operator and a female passenger on the trail, which is part of the Hopkinton-Everett OHRV Trail System.

Ryan Routhier, 33, of Warner was operating an ATV with Anne Klucinec, 21, also of Warner, as a passenger, according to Fish and Game. โ€œAs they approached a corner, Routhier accelerated rapidly and subsequently lost control of the machine causing it to roll onto its side. Both occupants of the ATV sustained serious bodily injury as a result of the rollover crash.โ€

Dunbarton Fire Department transported both occupants to Concord Hospital for further medical treatment.

โ€œNeither occupant was wearing any safety equipment such as a helmet, goggles, or proper riding attire at the time of the crash. It appears as though speed and alcohol are primary contributing factors to this crash; however, all factors surrounding the crash remain under investigation,โ€ Fish and Game said in a release.
