A rollover involving a tractor-trailer truck and a vehicle on a Massachusetts Turnpike ramp in Weston Tuesday afternoon sent four people to hospitals, according to state police.
The crash happened at about 12:40 p.m. on the Exit 14 ramp from I-90 eastbound.
Sky Ranger footage of the scene showed the truck on its side and a damaged car being towed away.
A preliminary investigation showed that the Freightliner truck, driven by a 28-year-old man from Monroe, Louisiana, was traveling in the left lane of the exit ramp when it rolled over onto a Nissan Sentra.
The driver of the Sentra, a 59-year-old Framingham man, was taken by medical helicopter to Lahey Hospital in Burlington for treatment of serious injuries.
The driver's passenger, a 24-year-old woman, was also taken to the hospital for treatment of minor injuries.
The driver of the truck and his 42-year-old male passenger from San Bernadino, California, were taken to Beth Israel Deaconess Medical Center in Boston for treatment of minor injuries.
