Spring is here and studded snow tires must be removed by midnight March 31.

Oregon state law allows motorists to use studded tires from Nov. 1 through March 31. Driving with studded tires after March 31 is a Class C violation and carries a $190 fine, the Oregon Department of Transportation reports.

The department's website says the state spends more than $11 million a year fixing roads and bridges damaged by studded tires.
