You are going to want to think twice before driving in Oregon today – and maybe over the next few days.

Roads may be dangerously icy throughout central and eastern Oregon as snow and slush have frozen, leaving roads in poor condition.

Oregon Transportation Department says to avoid travel until conditions improve, but if you must travel, be prepared for difficult winter driving conditions and have supplies in your vehicle to be ready for major delays.

Numerous crashes have occurred over the past several days.

Crews have been out working to clear away stranded or damage vehicles and treat roads to improve conditions.
