A six-vehicle chain-reaction collision on southbound Interstate 5 in Carlsbad sparked a massive fire and sent one person to the hospital early Saturday morning, February 14, 2026.
The incident occurred around 12:23 a.m. near Cannon Road when a motorcycle rear-ended a vehicle and went down in the lanes.
A sedan then struck the downed motorcycle, initiating a chain reaction involving three more vehicles. The sedan caught fire and was quickly engulfed, with the motorcycle trapped underneath.
One individual was transported from the scene with injuries of unknown severity.
Debris from the crash scattered across the roadway, prompting a temporary closure of all southbound lanes. The California Highway Patrol issued a SigAlert at 12:40 a.m. As emergency crews worked to clear the scene, the main roadway was reopened by 1:03 a.m., though the Cannon Road on-ramp remained closed.
During the response, dispatchers received reports of a physical altercation on the right shoulder, with two individuals fighting at the scene.
Emergency units from the Carlsbad Fire Department, including Engine 101 and Truck 107, responded to the incident.
The details are still being investigated. No further information is immediately available.
