VIDEO: 80 Dutchess car crashes in 9 hours

At least 80 auto accidents Sunday were caused by icy road conditions, according to officials.

A Union Vale accident left a man in critical condition, authorities said. And a fatal, one-car crash occurred in the Town of Poughkeepsie early Sunday morning.

Three people were hospitalized, two with "significant trauma," after a three-car accident on Freedom Plains and Lauer roads in LaGrangeville, according to LaGrange Deputy Fire Chief Barry Ward.

Freezing rain and ice accumulations made for hazardous travel conditions, according to the National Weather Service in Albany.

Skies should be partly sunny today and the temperature could reach 42 degrees, according to the National Weather Service. Skies tonight are expected to be partly cloudy and the temperature will likely drop to 20 degrees.

Skies on Tuesday should be mostly sunny, with a high temperature near 32 degrees. The temperature Tuesday night could fall to 12 degrees.

The icy conditions on Sunday affected "the entire tri-state area," and the state responded with 215 plows salting roads, according to a statement from Gov. Andrew Cuomo.

There were 64 property damage and 16 personal injury auto accidents from 7 a.m. until 4 p.m., and accident reports continued to come in on Sunday evening, said Dana Smith, coordinator for the Dutchess County Department of Emergency Response.

Smith credited the county's fire, police, emergency medical services, 911 dispatch and highway departments with a "great job."

The fatal accident happened around 6:52 a.m. in the Town of Poughkeepsie, and authorities said the roads were clear at the time.

A vehicle "left the roadway at a high rate of speed" at the intersection of East Cedar Street and Violet Avenue, went into a wooded area, struck a tree and caught fire, according to the Town of Poughkeepsie Police Traffic Enforcement Unit.

The driver of the vehicle died; that individual, the sole occupant, will likely be named Monday, said Town of Poughkeepsie police Capt. Paul Lecomte.

State troopers were dispatched by Dutchess County 911 to the crash in Union Vale on State Route 55 around 9:35 a.m. Sunday.

Major Singh Sandhu, 54, was driving eastbound on Route 55 when he lost control of his pickup on black ice, police said. Sandhu's truck crossed over the double-yellow line into the westbound lane, and went onto the north shoulder before leaving the roadway, striking a guide rail and rolling over multiple times.

The truck went down an embankment and Sandhu, who police said was not wearing a seat belt, was ejected when the vehicle rolled over.

Sandhu was found unconscious near the vehicle, police said.

He was treated by TransCare EMS and the Union Vale Rescue Squad before being transported to Mid-Hudson Regional Hospital, where he underwent emergency surgery for extensive head trauma, police said.

In LaGrangeville, responding firefighters "found three cars," one of which was on fire, around 10:35 a.m., Ward said.

There were two people in the car which was on fire, who got out before first responders arrived; two people and a dog trapped in the second car; and four people, one of whom was injured, in the third car, Ward said.

The two people who were trapped in the second car sustained "significant trauma," Ward said. "They're hospitalized at this point."

The chief said LaGrange had a "very busy day," responding to several auto accident, and six additional medical calls.

The fatal accident is still under investigation. Anyone with information is asked to call 845-485-3666.

Town of Poughkeepsie Police were assisted at the scene of the fatal crash by the Fairview Fire District, who cleared the scene by 10:21 a.m., along with the Dutchess County Medical Examiner's Office, state Department of Transportation and Town of Poughkeepsie Highway Department.

Fairview firefighters were assisted by the Roosevelt Fire District and Mobile Life Support Services Ambulance.

Investigation into the Union Vale crash is also continuing. State police were assisted by the Union Vale Fire Department.

LaGrange firefighters were assisted at the scene of the Freedom Plains Road accident by Beekman Fire District assistant Chief Greg Rayburn and the Pleasant Valley Fire Department.
