An off-duty police officer was critically injured in an early morning car crash in Queens, police said Saturday.

The 34-year-old cop was driving near the intersection of Nashville Blvd. and Lucas St. in St. Albans around midnight Friday when his car collided with another vehicle, then slammed into a telephone pole, officials said.

He was found lying on the road after the wreck with severe trauma to his head and body.

The two men in the other car, ages 20 and 28, suffered minor injuries, authorities said.

All three were taken to Jamaica Hospital, where the officer is listed in critical condition.

The NYPD’s Collision Investigation Squad is looking into the cause of the crash.
