An MTA bus driver was in critical condition Thursday after his bus careened into a Brooklyn Burger King overnight, according to police.

Officials said the 60-year-old driver lost control of the bus just after midnight and ended up crashing into the eatery on the corner of Fort Hamilton Parkway and Dahill Road in Kensington. The Burger King was closed at the time, police said.

A 60-year-old woman and a 23-year-old woman were the only passengers on the bus at the time, according to police. Both refused medical attention at the scene.

Police said the driver was taken to Maimonides Medical Center in critical but stable condition, and that he may have suffered a medical episode.
