WINDSOR — Police believe speed and inexperience may be to blame for Wednesday morning motorcycle crash on Route 17 that left an Augusta man dead.

Joshua Lash, 38, died at the scene, Capt. Daniel Davies of the Kennebec County Sheriff’s Department said.

Lash, formerly from Friendship, has a girlfriend and two infant twins who live in Augusta, Davies said. The girls were born in July, according to a birth announcement.

Deputies were called to the crash at 366 Augusta-Rockland Road around 3:30 a.m. Lash was found dead at the scene, Davies said.

“It appeared Lash was heading to work as he was wearing hip waders, rubber boots and carrying a backpack,” Davies said.

Investigators believe Lash was driving his 1990 Kawasaki Vulcan motorcycle east on Route 17 when he failed to negotiate a curve and veered off the road where he struck the driver’s side front end of a 2001 Nissan Altima parked in a driveway.

“Lash’s body was thrown several feet from the point of impact,” Davies said. “He was wearing a helmet at the time of the crash.”

Investigators subsequently determined Lash lacked a motorcycle endorsement on his driver’s license—meaning he was not legally permitted to operate a motorcycle on public roads—and he had not registered the motorcycle in his name.

“A recent bill of sale was found on his person,” Davies said.

Police believe driver inexperience, fog and driving too fast for conditions contributed to the crash.
