Adult Belt Law
Oregon law requires that all motor vehicle operators and passengers be properly secured with a safety belt or safety harness, unless all safety-belt equipped seating positions are occupied by other persons. This applies to passenger cars, pick up trucks, motor homes, and fee-based people transport carrying fifteen or fewer persons. Limited exemptions are allowed under ORS 811.215. Vehicle owners are required to maintain belt systems in working order.
Motor Homes
Motor homes are considered passenger vehicles under Oregon law and as such, adult belt and child seat requirements also apply to motor homes --- but only to forward-facing vehicle seating positions (those meeting federal safety standards for seat belt anchorages). Therefore, occupants should utilize all forward-facing belted positions before using side or rear-facing positions.
Commercial Vehicles
Oregon's safety belt law requires occupants of privately-owned commercial vehicles transporting 15 or fewer persons to use safety restraints including occupants of shuttles, taxis, limousines and vans. Among these types of vehicles, taxi cab drivers are the only occupants excepted from this rule.
ATVs
Oregon Parks and Recreation Department is implementing agency laws and rules relating to the use of ATVs.
Medical Exemptions
ORS 811.220 The Director of Transportation shall issue a certificate of exemption under ORS 811.215 for any person on whose behalf a statement signed by a physician, nurse practitioner, or physician’s assistant is presented to the Department of Transportation. The statement must clearly explain why the use of a child safety restraint system, safety belt or safety harness by the person would be impractical or harmful to the person by reason of physician condition, medical problem or body size.
A safety restraint exemption cannot be issued for commercial drivers per Federal Code 392-16.
