Robbie N replied: "Yes, when I drove through the mountain passes on a regular bases I had to keep a set of chains in my trunk. When they start the road closure process the first step is no one without chains. Then no one who doesn't have them installed and finally, completely closed, no one gets through. Get the chains, 4WD will help go, but does nothing to stop or turn. Chains may save your life. You don't want to risk that, do you?"
