A speeding driver is clinging to life and his passenger is dead after their car slammed into a Belt Parkway overpass support pillar in Queens late Sunday, authorities said.

The 20-year-old driver, who may have been racing on the highway in his Nissan Altima sedan, lost control and rammed into the concrete pillar near 150th Street just before 10:30 p.m., police said.

Both men in the car were rushed to Jamaica Hospital Medical Center, where the unidentified passenger, also in his 20s, was pronounced dead, authorities said.

The driver was listed in critical condition.

No criminality is suspected, police said Monday morning, adding that the investigation was ongoing.
