The Oregon Department of Transportation does not recommend driving in severe weather conditions, but the agency also says travelers need to use caution and observe a few common sense rules for navigating hazardous weather conditions.  Most important is to get to your destination before conditions turn nasty and unsafe, consider waiting until a storm passes to travel, and if you must drive look out for others and allow plenty of time to get where you are going.  Don’t abandon your vehicle, as it prevents crews from clearing the road and emergency services from getting to the people who need them.  If a storm knocks out power to traffic signals, treat intersections like an all-way stop.  And watch for plows, being sure to stay at least three car lengths back.
