GAITHERSBURG, Montgomery County, MD, Sept. 23, 2026 — An adult man was hospitalized with life-threatening injuries after being struck by a vehicle early Tuesday morning, September 22, on West Diamond Avenue near the ramp to southbound I-270 in Gaithersburg, Maryland.
Montgomery County Fire and Rescue Service crews responded around 12:44 a.m. to a report of a pedestrian struck at the interchange, according to the department. Fire and EMS units, including an engine, a paramedic engine, a paramedic ambulance and a supervisor unit, arrived on scene and found one adult male with trauma injuries.
Montgomery County Fire and Rescue's EMS Insight Highway Safety unit classified the man's injuries as Priority 1, meaning they were considered life-threatening, and transported him for treatment. Some lanes near the ramp were blocked while crews worked, the department said.
No further details on the man's condition, the vehicle involved, or the circumstances of the crash have been released. The incident remains under investigation.
Our thoughts are with those who were injured, and we wish them a full recovery.
WhatDetermines the Result of A Pedestrian Crashes Near Highway Ramps
Interchanges like the one where West Diamond Avenue meets I-270 create a mix of merging traffic, higher speeds and long crossing distances, conditions that engineers have found respond well to specific design fixes. Better street lighting at ramp junctions, shorter pedestrian crossing phases, raised medians that give people a safe place to pause, and roundabout-style ramp terminals that slow turning vehicles have all been linked to fewer and less severe pedestrian crashes in traffic safety research.
Vehicle design is import as well: taller, heavier front ends, frequent on pickups and SUVs, strike pedestrians higher on the body, closer to the chest and abdomen rather than the legs, and are more likely to knock a person down and run them over rather than over the hood. That difference in geometry has been tied to more severe outcomes when a larger vehicle is involved in a pedestrian strike compared to a smaller sedan.
According to the National Highway Traffic Safety Administration, 24 percent of pedestrians killed in traffic crashes were struck by hit-and-run drivers in 2023. That figure has pushed some jurisdictions to add cameras and better lighting at high-risk crossings, both to deter drivers from fleeing and to help identify vehicles after a crash.
Frequently Asked Questions
What should a pedestrian do after being hit by a car?
If possible, stay still and call 911 or ask a bystander to call. Avoid moving unless there's immediate danger, and let paramedics assess for injuries that may not be immediately obvious, such as internal trauma or head injuries.
Who has the right of way at a crosswalk?
Pedestrians generally have the right of way in marked and unmarked crosswalks, but drivers turning at ramps or intersections don't always see them in time, especially at night or where lighting is limited. Right of way doesn't replace the need for caution on both sides.
How can drivers reduce the risk of hitting a pedestrian?
Slowing down near ramps, intersections and crosswalks, and giving extra attention at night or in low-visibility conditions, gives drivers more time to spot and react to someone on foot.
What injuries are most common in pedestrian accidents?
Frequent injuries include fractures, head and brain trauma, spinal injuries, and internal injuries. Severity depends on vehicle speed and size at the point of impact.
What to Do After a Pedestrian Accident in Gaithersburg, MD
Anyone involved in or witnessing a pedestrian crash in Gaithersburg should call 911 right away so fire and EMS crews can respond. Even if injuries seem minor at first, a medical evaluation is worth getting, since some injuries like concussions or internal bleeding aren't obvious right away.
It also helps to get the names and contact information of any witnesses, and to request a copy of the police report once it's available. If you're able, photos of the scene, including lighting conditions and vehicle positions, can be useful later for insurance or medical follow-up purposes.
