Driving on ice when you don't have proper tires is also an accident waiting to happen, I don't know if its common for Portland residents to use winter tires maybe someone familiar with the region can weigh in?
The Portland metro region woke Wednesday morning to a thick coating of ice, after freezing rain fell beginning Tuesday afternoon and continued during the night. The layers of ice were expected to start gradually thawing later on Wednesday, but the freezing rain was the latest in what has been an extended period during which residents, businesses, transit providers, schools, shelters, government agencies and more have been forced to contend with below-freezing weather, high winds, snow and ice.
