Video obtained by The Post shows the moment a car bursts into flames following a crash on a Brooklyn highway early Thursday that left four people hospitalized.

The two-car smashup went down just after 5 a.m. on Prospect Expressway near Fort Hamilton Parkway in Windsor Terrace, FDNY officials said.

Footage shows a white Hyundai just inside the highway barrier engulfed in fire, while FDNY personnel attempt to quell the massive blaze.

A second car is seen smoking across the roadway.

The crash, the cause of which was not immediately known, left two people seriously injured and two with minor, non-life threatening injuries, authorities said.

All four victims were taken to Maimonides Medical Center and are expected to survive.
