SPRINGFIELD, Ore. - The Oregon Department of Transportation said motorists must take of their studded tires by the end of the day on Monday, March 31.
Without winter weather in the current forecast, ODOT officials said they don't plan to extend the state's studded traction tire season further into the year.
The metal studs come in handy when roads are coated in snow and ice, and are legal in Oregon for most of winter into spring.
Driving with studs after March 31 is a traffic infraction in Oregon, and could result in a $190 ticket for the driver.
ODOT says the annual road damage from the rut-making studs is estimated at $40 million.
Highway officials said drivers taking the mountain pass highways should check forecasts and road conditions ahead of time (check ODOT's page) as "short-term snow events" can occur well into May.
