The intersection is apparently controlled by a traffic signal. Officials indicate that, for as yet unknown reasons, the Trax disregarded the single indicated by the light. A collision consequently took place between the Trax and an eastbound Jeep Cherokee occupied by a 22-year-old woman.

Stone reportedly suffered serious injuries due to the accident. The woman from the Jeep sustained minor injuries, as well, according to reports. Additional details pertaining to this incident are not available at this point in time. The investigation is currently ongoing.

When a driver is said to have run a red light, it’s easy to conclude the case right there. But when a crash at a signalized intersection leads to serious injury, especially with no clear explanation for why the signal was missed, it’s worth asking whether there’s more to the story than just a moment of inattention.

1. Did the authorities thoroughly investigate the crash?
Any time a vehicle enters an intersection against a red light, investigators need to confirm not just what happened, but how. Was the light timing reviewed? Were traffic camera recordings checked? Was the vehicle’s speed consistent with an attempt to stop—or was there no change at all? These kinds of details help separate deliberate decisions from possible system errors or misunderstandings, and they’re key to determining what really caused the crash.

2. Has anyone looked into the possibility that a vehicle defect caused the crash?
If the Chevrolet Trax failed to respond when the driver tried to brake, or if the driver never received a proper warning from the vehicle’s assist systems, that would change the entire picture. Mechanical issues like brake failure or electronic glitches in the signal recognition or lane assist features could be involved. These issues can’t be diagnosed from crash photos—they require an in-depth inspection of the vehicle’s safety and control systems.

3. Has all the electronic data relating to the crash been collected?
Modern vehicles can tell a very specific story through data. Speed, braking input, steering movement, and system alerts can all be retrieved from the event data recorder. That information might confirm whether the driver attempted to stop or if there was no input at all. GPS and phone data could also point to possible distraction or navigation activity. If none of that information was secured early, the opportunity to fully understand the crash may already be slipping away.

Crashes in intersections aren’t always as simple as they look. When the outcome is serious, the investigation has to go deeper—because finding the truth often takes more than just reading the light.

  • Red-light crashes need signal data and vehicle movement analysis to confirm timing.
  • Brake or sensor failures could explain the inability to stop or react.
  • Digital records from the vehicle may reveal whether the driver acted—or tried to.
