A 24-year-old man from American Fork was killed Saturday night in a solo motorcycle crash on northbound I-15 near the 10600 South exit in Sandy, authorities said. Troopers shut down multiple lanes while crash investigators worked the scene, backing up part of the northbound freeway during the late-evening commute.
State officials identified the rider as 24-year-old Jeffrey Dylan Vreeken of American Fork and said he was pronounced dead at the scene. That information was reported by KSL, citing the Utah Department of Public Safety.
Emergency crews were dispatched late Saturday, and traffic was redirected while investigators collected evidence. Gephardt Daily reported the call came in at about 10:22 p.m., and that UDOT temporarily closed two right lanes and the 10600 South off-ramp during the investigation.
Investigation focuses on speed
Utah Highway Patrol troopers said they are examining excessive speed as a possible factor in the crash and noted that no other vehicles were reported as involved. Crash-reconstruction teams stayed on scene to document and measure evidence, according to Gephardt Daily.
Wider pattern: motorcycle deaths rising in Utah
State traffic data show motorcyclist fatalities have climbed sharply in recent years, with a 32% increase in rider deaths in 2025 compared with 2024, according to UDOT. The Utah Highway Safety Office notes that motorcycles are overrepresented in Utah road fatalities and lists excessive speed and lack of protective gear among the leading contributors to deadly crashes.
What investigators are likely to look for
As they reconstruct a motorcycle collision, investigators typically analyze the point of impact, skid marks, vehicle telemetry and whether the rider was wearing protective gear. Gephardt Daily reported that troopers remained at the scene while crash-scene teams processed and documented the area.
The Utah Highway Patrol is leading the investigation and has said that results from any reconstruction or toxicology testing will be released when available. Our condolences go out to Vreeken's family, friends, and all those affected.
