A video showing a Waymo self-driving car coming to a stop at a green traffic light before pulling away as it turns red has circulated online, prompting debate about whether the autonomous vehicle broke traffic rules. The clip has drawn attention because it appears to show the robotaxi behaving counterintuitively, raising questions about how the vehicle's sensors and software interpret traffic signals and whether its actions constitute a genuine driving error or a defensible safety-first manoeuvre.

The article does not provide further verified detail on the incident, such as the location, date, or Waymo's official response, beyond the headline description of the vehicle stopping at green and then moving through as the light changed to red. As with similar viral clips of autonomous vehicles, the footage has fuelled wider public debate over the reliability and legal accountability of self-driving technology.
