Extreme winter conditions on Interstate 5 Siskiyou Pass and the summits north of Grants Pass often require a conditional road closure – a requirement for all vehicles to use chains regardless of the type of vehicle or type of tire. ODOT and Oregon State Police maintain check points and will turn a motorist around if they aren’t prepared.
