A driverless Waymo robotaxi stopped in the middle of a Los Angeles street and refused to move as firefighters rushed toward a gas explosion that killed at least one person, forcing crews to work around the empty vehicle while a man lay dying in the wreckage.
The June 5 incident in the Crenshaw District has reignited sharp questions about whether autonomous vehicles are creating real dangers for first responders and the public they serve. Body-camera footage and bystander video captured the moment a firefighter ran up to the idle Waymo, looked inside, and said in disbelief: "Man, there's nobody in here."
One man was killed and at least five others were injured in the explosion, which ripped through a building near the intersection of Crenshaw Boulevard and Coliseum Street shortly before noon, the New York Post reported. The blast was so powerful it blew out walls, scattered debris across the road, and sent a plume of dust and smoke visible from blocks away. Southern California Gas Company crews later confirmed a gas leak as the cause.
Los Angeles Fire Department units responding to the explosion encountered the Waymo vehicle sitting stationary in the roadway. The car had no occupants and no visible reason to be stopped. It did not pull over. It did not yield. It simply sat there.
Firefighters attempted to get the vehicle to move. When it became clear no human was inside to respond, they were forced to route around it. The delay, though brief in real time, came during the most critical minutes of a mass-casualty response, when seconds can determine whether victims survive.
LAFD Captain Erik Scott confirmed the obstruction to reporters. He said the driverless car created a "direct impediment" to emergency operations and that crews had to adjust their approach to the scene because of it.
The blast tore through a single-story commercial structure. Witnesses described a thunderous boom followed by a wall of dust. People inside and near the building were thrown by the force of the detonation.
The man who died was found in the rubble. His identity has not been publicly released pending notification of next of kin. Five other people were transported to area hospitals with injuries ranging from moderate to serious, according to LAFD. At least two of the injured were in critical condition as of the most recent update from fire officials.
SoCalGas dispatched crews to the scene and confirmed a ruptured gas line. Investigators have not publicly stated what triggered the ignition. The company said in a statement that it was cooperating with fire investigators and the state Public Utilities Commission.
Waymo acknowledged the incident in a written statement. The company said it was "reviewing the situation" and that its vehicles are "designed to detect and respond to emergency vehicles." The company did not explain why the car failed to yield or move out of the path of responding fire apparatus.
Waymo added that it is "committed to working with first responders" and that it would share data from the vehicle's sensors and logs with LAFD if requested. The company did not say whether the car's software registered the approaching emergency vehicles or the explosion itself.
The statement did not address how long the vehicle remained stationary in the roadway before firefighters arrived, or what command the system would have needed to receive in order to clear the path.
This is not the first time autonomous vehicles have interfered with emergency response in California. San Francisco firefighters have documented dozens of incidents in which driverless cars from Waymo and other companies blocked fire lanes, stopped in intersections during active responses, or failed to yield to apparatus running lights and sirens.
In 2023, the San Francisco Fire Department reported that robotaxis had obstructed or complicated emergency scenes at least 55 times in a single year. One incident involved a driverless car running over a fire hose during an active structure fire. Another saw an autonomous vehicle drive into an active emergency scene and park on top of downed power lines.
San Francisco Fire Chief Jeanine Nicholson warned at the time that the problem was growing faster than regulators could address it. LAFD officials have echoed those concerns as Waymo expanded operations into Los Angeles.
Autonomous vehicles in California operate under permits issued by the state Department of Motor Vehicles and, for passenger service, the California Public Utilities Commission. Neither agency requires autonomous vehicle operators to demonstrate specific emergency-vehicle-yielding capabilities as a condition of their permits, according to filings reviewed by the Post.
California Vehicle Code Section 21806 requires all drivers to yield the right-of-way to emergency vehicles operating with lights and sirens. The law does not distinguish between human-operated and autonomous vehicles. Whether a software failure to yield constitutes a violation of that statute is a question regulators have not formally resolved.
State Assemblyman Matt Haney, who represents parts of San Francisco and has pushed for stricter autonomous vehicle oversight, called the Los Angeles incident "exactly what we warned about." Haney has introduced legislation that would require autonomous vehicle companies to implement verified emergency-vehicle-detection protocols and to submit incident reports within 24 hours of any obstruction event.
"People are dying, buildings are exploding, and we have ghost cars blocking the road. At some point we have to ask who is accountable when no one is behind the wheel."
That was Haney's statement to reporters following the Crenshaw District explosion.
LAFD's arson and investigation unit is leading the probe into the explosion's cause. Investigators will need to determine what caused the gas line to rupture, what ignited the leak, and whether the building's occupants had any prior warning of a gas odor or hazard.
Separately, LAFD officials said they intend to formally document the Waymo obstruction as part of the incident record. Whether that documentation leads to a referral to the DMV or the Public Utilities Commission remains unclear. Authorities have not said whether they will seek penalties against Waymo or request the company's sensor data through a formal process.
The California DMV told the Post it was "aware of the reported incident" and would review any complaints filed. The agency did not say whether it had opened an investigation or contacted Waymo directly.
The core legal tension is straightforward. When a human driver blocks a fire truck, that driver can be cited, arrested, or sued. When a driverless car does the same thing, the accountability chain fractures. The "driver" is an algorithm. The operator is a corporation. The regulator is a state agency that approved the vehicle's deployment.
Victims and their families may eventually test that chain in court. If the Waymo's obstruction delayed treatment for any of the injured, or if it slowed firefighters' access to the man who died, plaintiffs' attorneys will have a clear theory of liability. Waymo's deep pockets and its status as an Alphabet subsidiary make it an attractive defendant.
But litigation is slow, and the next explosion, fire, or mass-casualty event will not wait for a verdict. Fire departments across California have been asking for enforceable rules, not promises of cooperation, for years.
Residents near the blast site described chaos. Windows shattered in adjacent buildings. Car alarms triggered up and down the block. People ran from the area covered in dust.
One witness, a shop owner across the street who was not named in reporting, told the Post he felt the concussion in his chest before he heard the sound. He said he ran outside and saw the collapsed structure, then noticed the white Waymo vehicle sitting motionless in the road as sirens grew louder.
"The fire trucks were coming and this car was just sitting there. No driver. No nothing. Just sitting there like it was waiting for a passenger while a man was trapped in that building."
That account matched the body-camera footage released by LAFD, which showed the vehicle stationary and unresponsive as engine companies approached.
LAFD said it would issue a formal after-action report on the Crenshaw explosion within 30 days. That report is expected to include a section on the autonomous vehicle obstruction and any measurable impact on response time.
Waymo currently operates in Los Angeles, San Francisco, Phoenix, and Austin. The company has said it plans to expand to additional cities. Each expansion brings the same question local fire departments have been raising: what happens when a car with no driver blocks the path to someone who needs saving?
Haney's legislation is pending in committee. No vote has been scheduled. The bill's prospects are uncertain given the technology industry's lobbying presence in Sacramento.
A man is dead on Crenshaw Boulevard, and the car that blocked the road to reach him answers to no one. Until lawmakers and regulators fix that, every city with driverless cars on its streets is running the same bet: that the algorithm will get out of the way in time.
