" The voluntary recall on June 13 of the California-based tech company’s 3,871 vehicles is to fix its 5th-generation Automated Driving System (ADS) software so that it will recognize and avoid construction zones.

“Waymo’s mission is to be the world’s most trusted driver, and the data shows that we’re making roads safer in the communities in which we operate,” a Waymo spokesperson told The Epoch Times.

The National Highway Traffic Safety Administration’s (NHTSA) estimates that the entire fleet carries the software defect, according to the agency’s safety report.

“Under certain circumstances the [autonomous vehicles] may enter and drive at speed in freeway construction zones due to inappropriately prioritizing the avoidance of other freeway hazards and/or failing to recognize the construction zone,” NHTSA stated in the report.

Waymo investigated one such incident on April 11 and five on April 19 in which Waymo cars autonomously drove past ramp closure signs into freeway construction zones in Phoenix, Arizona, according to the report.

The company’s field safety committee implemented driving restrictions on April 20 until more improvements could be made, according to the report.

On May 18, seven Waymo vehicles in the San Francisco Bay Area entered freeway lanes in construction zones by driving between cones designating the lane’s closure. In this case, the software did not prioritize avoiding the other freeway hazards or failed to recognize the construction zone.

The safety committee put restrictions in place after the May incident, Waymo reported.

The recall is a notice of the company’s intent to improve its software and address the problems.

Waymo voluntarily restricted freeway operations in May while making improvements to the software to avoid other freeway hazards.

No collisions or injuries were reported as a result of the construction zone incidents. The company started offering public riders trips using freeways last November in the San Francisco, Los Angeles, and Phoenix areas."
