Three people were injured and westbound traffic on the Massachusetts Turnpike was halted for about an hour Tuesday afternoon when a tanker truck spun out of control after being struck by another vehicle, state police said.
The accident happened at about 3 p.m. near the 115-mile marker, police said.
According to initial reports, a Honda Pilot drifted off the road, struck the guardrail and spun back into the roadway, colliding with the right side of a Western Star tanker truck, police said.
The truck then jack-knifed and came to a stop blocking all three lanes.
A third vehicle, a Honda CRV, was unable to stop in time and became lodged under the trailer, police said.
The driver of the first vehicle that caused the accident, Andres Pineda, 59, of Hartford, was transported to Leonard Morse Hospital in Natick. His injuries were described by police as not life-threatening.
Two people in the vehicle that was stuck under the trailer, driver Trang Pham, 39, of Everett, and passenger Lisa Nguyen, 32, of Malden, each suffered minor injuries. They were taken by ambulance to a Framingham hospital, police said.
The driver of the tanker, Mark Letourneau, 42, of Worcester, was not hurt.
All three lanes of the pike were closed for an hour as EMS personnel treated the injured, and state police investigated the crash scene. When the debris was cleared and the road reopened, traffic was backed up for about 5 miles, police said.
