STAMFORD — Police say no one suffered life-threatening injuries during a horrific crash on Tresser Boulevard where one vehicle launched off the center divider and hit another vehicle head-on that was going in the other direction.

Sgt. Jeff Booth said the accident happened just after 6 p.m. Sunday when a BMW traveling westbound on Tresser Boulevard swerved into another car, also traveling westbound. The collision sent the other car spinning but the BMW ended up being launched over the median and into the east-bound lanes of Route 1.

There, the BMW ended up striking a Nissan head-on, Booth said.

A total of four people from the BMW and Nissan — two men, a woman and a 15-year-old boy — were rushed to Stamford hospital with various “significant” injuries, he said.

Booth said he did not know why the Stamford man swerved in his BMW, setting off the chain of events that left him into the opposite lanes of traffic on the busy artery that leads from Greenwich to Darien.

Booth said the 15-year-old was treated and released Sunday night. The two male drivers and a female passenger in the Nissan were injured in the crash.

Booth said there was no evidence that the man was under the influence and it did not appear that speed played a large role in the crash. He estimated that the cars were traveling between 30 to 40 mph when the head-on crash occurred.
