Driver pulled from crashed truck seconds before it explodes

This police bodycam footage begins in mundane form, with a pulled-over motorist being issued a ticket for some traffic infraction or other. A loud crash is heard, and while we can't see it, we know it's trouble because the cop lets the motorist off and dashes back to his car. He races to the scene of the accident and we see the box truck wrecked in the highway, flames dancing around the windshield and tires. The officer and another rescuer haul the disoriented driver from the fire. Barely a second or two later, a roaring noise is recorded and we soon see that the entire cabin is engulfed.

The driver suffered minor injuries, according to New Jersey State Police, and they don't know what caused the crash.
