Bexar County, TX — July 1, 2024, Dalia Aguilar-Williams and another person were injured due to a car accident just before 6:00 p.m. along Shaenfield Road.

According to authorities, 45-year-old Dalia Aguilar-Williams was traveling in a southwest bound Mercedes-Benz SUV at the Shaenfield Road and Cavern Hill intersection when the accident took place.

The intersection is controlled by a traffic signal. Officials indicate that, for reasons yet to be confirmed, a northwest bound Ford Escape occupied by a 39-year-old woman ran the red light. A T-bone collision consequently occurred between the front-end of the Escape and the left side of the Mercedes-Benz.

Both Aguilar-Williams and the woman from the Escape reportedly sustained serious injuries over the course of the accident. They were each transported to local medical facilities by EMS in order to receive necessary treatment. Additional details pertaining to this incident are not available at this point in time.

When a collision happens in a signal-controlled intersection and both drivers end up seriously hurt, it’s easy to assume someone just made a poor decision. But serious consequences call for more than just assumptions—they call for evidence, follow-through, and the kind of questions that don’t always get asked.

1. Did the authorities thoroughly investigate the crash?
Red-light crashes may seem straightforward, but timing disputes are common. Did investigators gather data to confirm when each signal phase changed, and did they analyze whether either driver may have entered the intersection during a yellow or delayed reaction period? Details like point of impact, direction of travel, and any witness accounts are crucial in sorting out a T-bone crash. If those steps weren’t taken, there may be important context still missing.

2. Has anyone looked into the possibility that a vehicle defect caused the crash?
If the Ford Escape failed to stop in time, was it because of driver inattention—or could there have been a brake issue or sensor failure? In a newer SUV, systems like forward collision warnings or automatic braking are often expected to play a role. Similarly, if the Mercedes-Benz experienced any delay in acceleration or failed to detect the incoming vehicle, that could have worsened the impact. But these factors can’t be ruled in or out unless a detailed inspection was done shortly after the crash.

3. Has all the electronic data relating to the crash been collected?
Both vehicles likely recorded vital crash data—speed, throttle position, brake use, and possibly even driver assistance alerts. That information can tell a clearer story about what happened in the seconds before impact. In cases involving alleged red-light violations, this data often helps confirm whether either driver tried to stop, hesitated, or was caught off-guard. Without it, investigators are often left to piece things together with far less accuracy.

Crashes in intersections with working signals shouldn't leave room for confusion—but unless someone checks the timing, checks the vehicles, and checks the data, confusion is exactly what remains.

Takeaways:

• T-bone crashes at signal intersections require confirmed timing and movement analysis to determine fault.
• System or mechanical issues in either vehicle could have affected driver control and collision avoidance.
• Crash data recorders offer crucial insights into pre-impact speed, braking, and system warnings.
