The two young New Hampshire women who sustained serious injuries in a moped accident on the Vineyard Saturday are both recovering.

Both are division one lacrosse players at the University of Massachusetts at Lowell, according to the university website.

Noelle Lambert, 19, of Manchester, N.H., lost her leg in the accident when the moped she was operating hit a dump truck on Barnes Road. Her passenger on the moped, Kelly Moran, 19, of Newfields, N.H., was also injured although less seriously.

Ms. Lambert was airlifted to the Boston Medical Center shortly after the accident early Saturday afternoon. Late Monday afternoon, she was listed in fair condition.

Ms. Moran was rushed into surgery at the Martha's Vineyard Hospital Saturday. A report on her condition was not available from the Vineyard hospital on Monday, although on Sunday Oak Bluffs police said she was recovering and doing well.

Both women are listed as members of the women's lacrosse team at the University of Massachusetts Lowell, a division one school. According to the school website, Ms. Lambert is an attacker and Ms. Moran a midfielder. Both were named to the America East All-Rookie team this year.

Oak Bluffs police, fire and EMS were called to the scene on Barnes Road at around 12:35 p.m. Saturday after the moped being operated by Ms. Lambert and Ms. Moran hit the dump truck, near the entrance to the youth tennis center just off the roundabout. Sgt. Steven Conley told the Gazette Sunday said an investigation into the cause of the crash found the moped, traveling south on Barnes Road, had moved too far to the right toward the shoulder of the road, then over corrected and moved too far to the left, colliding with the truck.

The operator of the truck was Augustus (Brant) Ben David of West Tisbury. Mr. Ben David was not injured and no citations have been issued, police said.

“For Mr. Ben David this is just an unfortunate circumstance, and obviously for the women as well,” Sergeant Conley said.

The two women were visiting the Island and had rented the moped from Ride On rentals in Oak Bluffs, police said.

Both women were stabilized at the scene, Oak Bluffs fire chief John Rose said.

A portion of Barnes Road was closed for a time following the accident. Edgartown police assisted with traffic control during the response.
