Waymo issued a recall for all of its vehicles using the 5th Generation Automated Driving System after they entered closed construction zones on the freeway.

The vehicles traveled at freeway speeds in closed lanes, which Waymo noted "increases the potential for collisions."

This is the second Waymo recall in under two months, as an earlier software fix addressed an issue where the cars could drive into flooded lanes of traffic on higher-speed roads.

Waymo recalled all 3,871 of its robotaxis using its 5th Generation Automated Driving System (ADS) on Wednesday, over concerns that the vehicles could drive at highway speeds into lanes closed for construction. The recall, first reported by Reuters, comes after multiple instances of the robotaxis either driving onto closed highway onramps or into closed lanes on active freeways.

"Under certain circumstances, the AV 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," the recall notice says.
