- A semi carrying seven Teslas caught fire on I-5 in Sylmar, shutting down lanes for hours.
- Firefighters faced a prolonged blaze due to EV batteries, though no injuries were reported.
- Traffic snarled well past midnight; the cause of the fire was still under investigation.
Traffic in California isn’t often pleasant, but it was even worse than normal on Saturday night. Drivers on the southbound side of the 5 freeway saw something rare: a semi truck fully engulfed in flames that spread to new Teslas on the attached trailer. It took crews several hours to get the conflagration under control.
Road users reported the fire at around 5:35 p.m. local time. Based on the video of the scene, it appears as though the fire began on the truck itself and spread. In some footage, it’s clearly growing in and around the cab. Later on, it spreads up to the Tesla Model Y directly above the cab. From there, it seems that it worked its way back, damaging all but two cars on the trailer.

According to SignalCV, authorities confirmed that the driver escaped without injury. California Highway Patrol officers issued a SigAlert for two hours just before 6 p.m., but that ended up lasting far longer. At 10 p.m., it was still telling locals to expect a two-hour backup in the area. Some vehicles had to sit for so long that they ran out of fuel on the highway.

No doubt, the lithium-ion batteries onboard made putting the fire out harder than usual. Notably, it’s unclear at this point what started the fire to begin with. One person who claims to have seen the fire early on said that it began near the back tires of the truck. Reviewing topography from the area also shows a steep decline of several hundred feet on I-5 just before the location of the parked semi.
While we can’t be definitive, the combination of that statement and the steep decline suggests that overheated brakes could’ve played a role in the initial fire. At this point, we’ll have to wait for authorities to release additional information. We’re just happy that everyone escaped without injury.
