Police say a tractor-trailer accident on the Cross Bronx Expressway early Saturday morning has left one person dead.

They say officers were called after a Toyota smashed into the back of a tractor-trailer just after 1 a.m.

Officials say the driver of the Toyota, 31-year-old Jose Rivera-Baez, was trying to switch lanes when he crashed into the other vehicle. They say the crash caused the airbags to deploy in the Toyota.

Police say the tractor-trailer was sitting on the expressway near Exit 2 with its flashers on.

EMS transported the Rivera-Baez to NYC Health + Hospitals Lincoln, where he was pronounced dead.

The 35-year-old driver of the tractor-trailer was in the vehicle when the accident happened, but was not injured.
