A 48-year-old Richland man was injured after he failed to negotiate the curve on the Interstate 182 ramp from Fourth Avenue in Pasco.
Richard D. Shumate was ejected from his 2010 Harley-Davidson motorcycle about 4:50 p.m. Sunday, according to Washington State Patrol.
Shumate was transported to Richland's Kadlec Regional Medical Center. His condition was not available Sunday night.
He was wearing a non-USDOT-compliant helmet, according to WSP. Drugs and alcohol were not involved in the accident.
The cause was inattention, the state patrol said. Shumate was charged in connection with having his wheels off the roadway.
