Bexar County, TX — August 24, 2024, William Gallogly was injured following a single-car accident at approximately 2:10 a.m. along Bandera Road.
According to authorities, 29-year-old William Gallogly was traveling in a northbound Toyota Sienna minivan on Bandera Road (State Highway 16) in the vicinity southwest of the Farm to Market 1560 intersection when the accident took place.

Officials indicate that, for as yet unknown reasons, the minivan failed to safely maintain its lane of travel. It reportedly veered off of the left side of the road, following a grass ditch in the median before entering a drainage area and heading up the embankment where it crashed into a light pole. Gallogly reportedly sustained serious injuries over the course of the accident. Additional details pertaining to this incident are not available at this point in time.

When a vehicle veers off the road and crashes into a fixed object, particularly in the early hours of the morning, it’s easy to assume the driver simply drifted or overcorrected. But in my experience, especially in single-vehicle crashes like this one on Bandera Road, surface-level assumptions often miss deeper, more complex issues. To truly understand what caused the minivan to leave the roadway and result in serious injuries, there are three critical questions that should be asked.
First, did the authorities conduct a thorough investigation? At 2:10 a.m., low lighting and reduced visibility can significantly affect a driver’s ability to navigate the roadway. Investigators should consider whether the road was adequately lit, whether signage and lane markings were visible, and whether there were any obstructions, road debris, or sudden changes in road surface that might have prompted an evasive maneuver. If those conditions weren’t fully documented, an independent crash reconstruction may be necessary to determine whether the vehicle left its lane due to something external.
Second, has anyone explored whether a mechanical failure contributed to the crash? A sudden drift to the left and subsequent loss of control could point to a problem with the steering system, suspension, or even the minivan’s electronic driver-assistance systems. Tire issues—particularly on older vehicles or those with high mileage—can also play a role. These are not always apparent at the scene and require a forensic inspection of the vehicle while it remains in its post-crash condition.
Lastly, has all the electronic data from the vehicle been collected? The Toyota Sienna likely contains an event data recorder that stores critical information about the vehicle’s behavior in the moments before the crash—speed, throttle position, brake application, and steering angle. That data can help determine whether the driver attempted to correct the vehicle’s path or if the vehicle responded improperly. Supplementary data, such as dashcam footage or GPS logs, could provide additional insight. As always, this information is time-sensitive and should be retrieved promptly.
When someone is seriously injured in a crash with no immediately clear cause, it’s not enough to speculate about driver behavior. Asking these questions is the least that can be done to ensure that those affected by this crash get the clarity and closure they deserve.
