LOWELL -- A 40-year-old Dracut man is in critical but stable condition after he was injured in a single-vehicle crash into a parked tow truck on Mammoth Road late Friday night, according to police.

Officers were called to the area of 325 Mammoth Road just before midnight, where they found a Chevrolet pickup truck driven by James Garon, of Dracut, smashed into a flatbed tow truck, according to Capt. Kelly Richardson.

Witnesses told police the pickup crossed the double-yellow line and drove straight into the tow truck, Richardson said. The driver initially got out of the truck on his own, but soon collapsed, complaining of stomach pain, Richardson said.

Paramedics called for a medical helicopter but none were flying due to the weather. Richardson said Garon was taken to Lowell General Hospital/Saints Campus, and then transferred to a Boston hospital.

The crash is under investigation by the Lowell Police Department Traffic Unit, which is reconstructing what happened. No charges were immediately filed, but an investigation is ongoing.
