SOUTH BRUNSWICK, NJ – Police charged an East Windsor man with causing a chain reaction crash on Route 130 north during Wednesday afternoon's rush hour.

According to police, Karmvir Singh, 24, was driving north on Route 130 around 5:39 p.m. Wednesday afternoon when his 2014 Honda Accord struck three vehicles that were stopped for traffic in the left lane, just north of Stults Road.

The impact pushed a 2001 Infiniti QS4 SUV, operated by Cyril West, 59, of Somerset, on top of a third vehicle, a 2012 Subaru Impreza operated by Plainsboro resident, Erica Kurey, 22.

That impact forced the Impreza into the bumper of a 2007 Accura MDX, operated by Pedro Melendez, 61, of North Brunswick, police said.

According to police, witnesses to the accident reported that Singh was “driving erratically,” changing lanes and driving at a high rate of speed prior to the crash.

Singh, who police say was not wearing a seatbelt, struck the windshield of the vehicle during the accident and was taken to Robert Wood Johnson University Hospital in New Brunswick for treatment of facial and head lacerations.

He was kept overnight for observation, police said.

West was also taken to Robert Wood Johnson complaining of knee and neck pain.

Police said there were no other injuries.

Singh was cited for reckless driving, making an unsafe lane change, failure to wear a seatbelt and obstructing traffic, police said.

The crash closed both northbound lanes of Route 130 for about 30-40 minutes as three of the four vehicles were towed from the scene.

The accident backed up traffic for several hours during the evening rush, police said.
