WASHINGTON, July 8 (Reuters) – The head of the U.S. National Highway Traffic Safety Administration said Wednesday that self-driving car companies must quickly address a “clear pattern” of ​driverless vehicles interfering with law enforcement and other first ‌responders.

Jonathan Morrison, who heads the U.S. vehicle regulatory agency, said in a letter to the industry that NHTSA has documented multiple instances of AVs driving into active emergency scenes, and other incidents when the vehicles “blocked the paths of ‌ambulances ​and firefighters, or failed to recognize and ⁠respond to basic safety ⁠conditions like flashing lights, flares, smoke, fire, and traffic cones.”

“Let me be clear: the inability to detect and appropriately respond to such situations represents a functional insufficiency,” he said in the letter.

NHTSA ​said it would schedule meetings with vehicle developers by the end of the month to solicit solutions. It called on AV ⁠developers and operators to focus on ⁠fixing the problem.

“An AV that cannot safely interact ​with first responders is a danger to the general public,” the ​letter said.

NHTSA did not identify any specific incidents, or name ‌the companies receiving the letter.

Local media in Texas reported a Waymo self-driving vehicle in Dallas in late May partially blocked a route fire trucks were using to get to an apartment building ⁠on fire.

Waymo did not immediately respond to a request for comment. Other videos have reportedly shown Waymo vehicles blocking an ambulance and driving through ⁠an active police ‌scene.

Both NHTSA and the National Transportation Safety Board ⁠are investigating separate incidents involving Waymo self-driving vehicles. ​One ‌involved such vehicles passing stopped school buses with ​their lights ⁠activated in violation of Texas state law.

The other occurred January 23, when a self-driving Waymo struck a nine-year-old girl in a school zone in Santa Monica, California, as she ran across the street from behind a double-parked SUV toward the school.
