AZCentral said the incident occurred on June 19. Phoenix police pulled over the driverless taxi with no occupants inside for driving in an oncoming traffic lane near Seventh Avenue and Osborn Road. 

Just after 11 am on June 19, a Phoenix police officer initiated a traffic stop on the Waymo, according to police dispatch records. The vehicle drove into oncoming traffic, ran a red light and "FREAKED OUT," said the dispatch records, which are typed in all capital letters. -AZCentral

Waymo blamed the incident on "inconsistent construction signage" that forced the SUV into an oncoming lane of traffic. It added that the vehicle was "blocked from navigating back into the correct lane" for around 30 seconds.
