Because winter-like conditions have extended into spring, Oregon and Washington have pushed back the deadline for the removal of studded snow tires. They must now be removed by April 11. http://news.opb.org/article/7027-oregon-and-washington-extend-studded-tire-season/
The Oregon Department of Transportation (ODOT) not only considered the recent weather conditions, but also the feedback it heard from residents who live or travel at higher elevations.
Just this past Tuesday, even though spring has officially started, winter-like weather was blamed for a number of accidents and road closings.
In Oregon, drivers can be fined $190 if they don’t remove their tired by the new deadline of April 11. In Washington, the penalty is $124.
Studded tires rack up $11 million in damage to Oregon’s roads every year, according to ODOT.
