CHANTILLY, Fairfax County, Va., Sept. 20, 2026 — A woman using a wheelchair died after being struck by a car while crossing Route 50 in Fairfax County Friday night, September 18. The crash happened at the intersection with Plaza Lane in the Greenbriar area.
The police said officers responded to the intersection shortly before 7:30 p.m. Authorities identified the victim as Theresa Flynn, 53, of Chantilly, who was reportedly in a manual wheelchair moving north across the roadway when she was hit.
Investigators said Flynn was struck by a Kia Rio traveling west on Route 50. She was taken to a hospital, where she was pronounced dead. The driver was not injured and remained at the scene.
Detectives said preliminary information does not indicate that speed or alcohol was a factor for the driver. The crash remains under investigation, and Fairfax County police have asked anyone with information to contact the department's crash reconstruction unit or submit an anonymous tip.
We are deeply sorry for the loss suffered by the victim's family.
Where Pedestrian Crashes Concentrate on Roads Like Route 50
Wide, high-speed arterial roads built to move heavy traffic through suburban commercial areas tend to produce a steady share of pedestrian crashes. These roads usually have multiple lanes in each direction, long distances between signalized crossings, and posted speeds well above what's typical on residential streets. A person crossing on foot, or in a wheelchair, may need more time to clear the roadway than a signal cycle allows, especially at intersections that were not designed with pedestrian timing as a priority.
Unsignalized or partially controlled intersections along these corridors add another layer of risk. Drivers turning or continuing through are focused on gaps in vehicle traffic and may not expect or watch for someone crossing outside a marked crosswalk. Lighting, sightlines, and the width of the crossing all affect how visible a pedestrian is at night.
According to the National Highway Traffic Safety Administration, 84 percent of pedestrian fatalities occurred in urban areas in 2023. Suburban commercial corridors like Route 50, which combine urban traffic volumes with wide, high-speed lanes, share many of the same conditions that make these crossings difficult for people on foot or using mobility devices.
Frequently Asked Questions
What can drivers do to avoid hitting a pedestrian?
Slowing down near intersections and driveways, scanning both sides of the road before turning, and giving extra time at crossings where visibility is limited can help drivers spot pedestrians sooner, particularly at night or in low light.
What injuries are common in pedestrian crashes?
Pedestrians struck by vehicles frequently suffer head trauma, broken bones, and internal injuries. The severity generally depends on the vehicle's speed and the point of impact.
What usually causes pedestrian accidents?
Common factors include driver distraction, failure to yield at crossings, poor lighting, and roadways with long gaps between signalized crossings that push pedestrians to cross where drivers aren't looking for them.
Does vehicle speed affect a pedestrian's chance of survival?
Yes. Research consistently shows that a pedestrian's likelihood of surviving a crash drops sharply as vehicle speed increases, since faster impacts transfer more force and leave less time for either party to react.
What to Do After a Pedestrian Crash in Chantilly, VA
Anyone involved in or who witnesses a pedestrian crash should call 911 immediately so emergency responders can reach the scene quickly. Even if injuries seem minor at first, a medical evaluation is important, since some injuries, especially head and internal injuries, aren't immediately obvious.
Staying at the scene and cooperating with responding officers helps ensure an accurate report. If you saw the crash or have information that could help investigators, reporting it to local police adds detail that may not otherwise be available. Fairfax County residents can also review pedestrian safety resources from the county to better understand risk areas near their own neighborhoods.
