A driver severely injured both his legs in a high-speed crash on a Brooklyn parkway early Sunday, cops said.

The 33-year-old man behind the wheel was driving on the Belt Parkway near Pennsylvania Avenue in East New York around 4 a.m. when he suddenly lost control and crashed, cops said.

He was the only driver involved in the accident, and it wasn’t immediately clear what he crashed into.

He was rushed to Brookdale Hospital Medical Center with serious injuries to both of his legs, according to police.
