Newberg motorcyclist who died after solo crash on I-5 near Marquam Bridge identified

A 60-year-old Newberg man has been identified as the motorcyclist who died in a single-vehicle crash on southbound Interstate 5 near the Marquam Bridge on Friday. Preliminary information indicates Jason A. Doherty was riding a 2002 Harley Davidson motorcycle with a sidecar southbound on I-5 when, after negotiating a left turn off the Marquam Bridge, the motorcycle suddenly veered at a sharp angle out of the lane of travel for an unknown reason and struck the jersey barrier. Portland police said officers responded at 6:18 p.m. Friday, June 19 to a report of a crash on southbound I-5 at exit 299A/Lake Oswego, just south of the Marquam Bridge. Police said no other vehicles were involved.

Portland Fire & Rescue also responded and performed lifesaving measures before the rider was determined to be dead. Paramedics determined the rider was dead at the scene. Police said Doherty was wearing a helmet, but it was a half-shell novelty helmet and not approved by the Department of Transportation . His family was notified. DOT's website states that while all motorcycle helmets sold in the United States are required to meet the federal standard and have the DOT certification label, "there are online and brick-and-mortar retailers who sell what are known as 'novelty helmets' that do not meet our safety standards. There are also fake DOT labels being sold to put on these unsafe helmets." The Portland Police Traffic Division Major Crash Team investigated the crash, which shut down southbound I-5 south of the Marquam Bridge at the time of the crash as traffic was routed from the Marquam Bridge onto northbound I-405. The traffic investigation continues, and investigators are asking anyone with information who has not already spoken to police to submit a tip through the online portal. The case number is 26-178327. Police said the crash was Portland’s 20th traffic-related death this year and the second in a span of 25 hours. It was the eighth this year involving a motorcycle or gas-powered scooter.
