State police are looking for a driver who fled the scene of an accident in Danbury that backed up I-84 westbound traffic for miles and hours Thursday morning.

There was a two-vehicle crash, involving a 2018 Chevrolet Malibu LS and 2004 Chevrolet Trailblazer, just before Exit 4 around 3:44 a.m.

The Trailblazer sideswiped the Malibu, causing both vehicles to leave the roadway, police said.

The driver of the Trailblazer fled the scene before troopers arrived, leaving behind two passengers —34-year-old Jose Rosas and 33-year-old Jesus Rosas, both of Ridgefield.

“This case is still active and investigators have not identified the operator at this time,” Trooper Josue Dorelus from the Connecticut State Police Public Information Office said Friday.

Both passengers, as well as the 41-year-old driver of the Malibu, sustained minor injuries.

The Trailblazer is registered to a resident of Main Street in Ridgefield. The vehicle registration address is also where the two passengers live, according to police.

Approximately 50 feet of chain link fence was damaged in the crash, and both vehicles had to be towed from the scene.

Two lanes of traffic were shut down as emergency personnel responded to the scene, causing heavy westbound delays between Route 7 and the New York state line with travel speeds in the single numbers.

Even after lanes reopened around 8:30 a.m., it still took drivers 91 minutes to travel eight miles westbound on I-84, according to the state Department of Transportation.

Anyone with information on the driver of the Trailblazer is asked to contact Trooper Ryan Lopez at 203-267-2200.
