A 48-year-old Sumas man died Friday night after suffering a medical episode while driving northbound on Reese Hill Road, also known as State Route 547, in Whatcom County. The crash was reported at approximately 11 p.m. on September 18, 2026, and emergency crews responded to find the driver deceased at the scene, according to a press release from the Washington State Patrol.
The driver was operating a black 2006 Ford Expedition when the vehicle left the roadway to the right and struck a tree. The Expedition came to rest off the pavement without blocking traffic. Washington State Patrol investigators determined the crash was caused by a medical episode rather than driver error, impairment, or excessive speed. Drugs and alcohol were ruled out as contributing factors. The vehicle was totaled and towed from the scene.
Details of the Crash
Reese Hill Road, which runs northward from the Sumas area toward the U.S.-Canada border, is a two-lane rural highway that sees a mix of local traffic and commercial vehicles in an agricultural part of Whatcom County. The crash occurred in the northbound direction, and first responders including Washington State Patrol troopers were dispatched shortly before midnight.
According to the Washington State Patrol, the driver was not wearing a seatbelt at the time of the collision. That determination was noted in the official incident record, though investigators attributed the fatal outcome primarily to the medical event rather than to seatbelt non-compliance alone.
The Washington State Department of Transportation confirmed that Reese Hill Road was closed in both directions following the crash as emergency crews worked the scene. The road reopened at approximately 3 a.m., meaning the closure lasted roughly four hours overnight. WSDOT did not report any secondary incidents related to the road closure during that window.
Sumas and Reese Hill Road
Sumas is a small city of roughly 1,500 residents sitting directly on the U.S.-Canada border at the northern end of Whatcom County. The community is primarily agricultural in character, surrounded by dairy farms and berry fields that define much of the landscape in this part of Washington State. State Route 547, which includes the stretch of Reese Hill Road where this crash occurred, is one of the primary north-south routes in the area, connecting the Nooksack River valley to the border crossing at Sumas.
The road passes through territory that is relatively remote by Whatcom County standards, with forested areas and farmland bordering long sections of the highway. Nighttime driving on this route involves limited ambient lighting, which can make hazards harder to spot quickly. Emergency response times in rural parts of the county can be longer than in Bellingham or Ferndale, which underscores the importance of rapid dispatch when calls come in.
Medical Episodes and Traffic Safety
Medical episodes behind the wheel are a recognized cause of single-vehicle crashes across Washington State and nationally. Cardiac events, seizures, diabetic emergencies, and strokes can all cause a driver to lose control suddenly and without warning. By definition, these crashes are difficult to prevent through conventional traffic enforcement measures, since the driver does not make a conscious choice to drive impaired.
The Washington State Department of Licensing has provisions for medical reviews of drivers who have experienced certain health events, and physicians in Washington are permitted to report patients to the DOL when they believe a medical condition poses a significant risk behind the wheel. These reviews can result in driving restrictions or license suspension, though the system relies heavily on voluntary reporting.
Washington State Patrol releases crash reports for incidents involving fatalities as part of its public information practices. Those reports are available through the patrol's public records process. The identity of the Sumas man was not released in the initial press memo, which is standard practice in the immediate aftermath of a fatal crash while next of kin are being notified.
What Residents Should Know
Fatal crashes on rural Whatcom County roads have occurred at several points over the past year, highlighting the risks of driving on two-lane highways with limited shoulders and no median separation. If you or someone you know has a medical condition that could affect safe driving, speaking with a physician about any necessary restrictions is an important step.
Seatbelt use remains the single most effective way to survive a crash in Washington State. Washington State Patrol data consistently shows that unbelted occupants face dramatically higher fatality rates in crashes of all types, including single-vehicle incidents. Washington has a primary seatbelt law, meaning officers can stop a vehicle solely for seatbelt non-compliance.
Anyone with information about the crash or about the driver is encouraged to contact the Washington State Patrol's Bellingham detachment. For those following traffic and road safety news in Whatcom County, prior coverage of road incidents in the region provides context on the patterns seen on local highways throughout the year. Earlier this year, a major I-5 closure near Bellingham also reminded residents how quickly road conditions can change on key regional routes.
