Firefighters were called to douse a gravel truck that caught fire on the 5 Freeway in Boyle Heights, prompting a Sigalert Thursday morning.
The incident was reported shortly before 3:30 a.m. on the northbound side of the 5 Freeway just south of the 10 Freeway, according to the California Highway Patrol’s traffic incident log.
Arriving fire crews found the gravel truck engulfed in flames near the freeway’s right shoulder.
Video from the scene showed one firefighter battling so much smoke and fire that the gravel truck was hardly visible.
The crew managed to douse the fire quickly despite the dramatic scene.
The truck’s driver did not appear to be injured but the incident prompted officials to issue a Sigalert for the slow lane.
Officials were hopeful the lane would reopen around 5:30 a.m.
