A three-vehicle collision May 4 that sent one person to Penobscot Bay Medical Center was the result of drivers failing to properly observe the signs and signals at the intersection of Routes 17 and 90, according to Rockport Police Department Patrol Officer Dana Smith.

“This is the second time this kind of accident has taken place,” Smith said.

At about 9:30 a.m., Richard Martin, 53, of Bradley was driving a white 2010 Chevrolet box truck and was traveling west on Route 17. According to Smith, Martin was turning onto Route 90, called West Street in Rockport, and assumed the green light at the intersection gave him the right of way.

“Instead of waiting patiently for the green left arrow, he went into oncoming traffic,” Smith said.

Michael LaChance, 45, of Augusta was driving south on Route 17 in a black 2000 Pontiac Grand Am

“He basically had a yellow light as he entered the intersection,” Smith said. According to Smith, LaChance said he was surprised the truck pulled in front of him.

“In order to avoid the collision he veered right onto West Street and was struck by the truck on his driver’s side,” Smith said. He said LaChance’s vehicle collided with a silver 2004 Toyota Corolla that was at the light on West Street waiting to make a right turn onto Route 17. The driver of the Corolla was Gary Hall, 53, of Waldoboro. Hall’s wife, Rebecca Hall, was a passenger and complained of shoulder pain and was transported to PBMC by a Camden First Aid Association ambulance.

Smith said the approach on Route 90 from Warren and Tolman Pond is a single lane. He said the road was widened near the intersection in order to allow emergency vehicles room to pass when the intersection is busy.

“Where LaChance collided with [Hall’s vehicle] it is actually a single lane approach,” Smith said. “It’s hard to enforce it all. It’s not really wide enough for two vehicles.”

He said a fourth vehicle missed being involved in the accident by about 6 inches, and he cautioned drivers to read the signs and signals at the busy intersection.

“If you’re tuning left onto West Street, remember there is a green arrow,” Smith said. “A green light means that those on Route 17 have the right of way.”
