A New York State Police trooper narrowly escaped injury by jumping over a concrete barrier to avoid a chain reaction crash caused by an alleged impaired driver this week.

The incident happened just before 7:30 p.m. Wednesday when the state police responded to a single-vehicle crash on Interstate 90 in Tonawanda, the agency stated in news release. A trooper was outside their cruiser when a 2014 Dodge Ram pickup truck with a dolley trailer struck a car, which crashed into the trooper's parked cruiser.

"Seeing the oncoming collision the Trooper moved from the center of the roadway and hopped over the concrete center barrier into the northbound side of travel to avoid being struck."

The trooper was uninjured in the incident. Photos from the scene showed extensive damage to the cruiser, however.

The pickup truck driver, identified as James R. Phalen, also wasn't hurt. He was arrested for driving while intoxicated and other offenses.

The crash is under investigation.
