You might not have a choice! If enough people in front of you have stopped under the overpass, so will you. Sometimes visibility is so reduced that being in an underpass is a relief. I once emerged from an underpass after a particularly severe storm (possibly tornado) only to find an 18-wheeler stopped, facing me, a short distance from the over pass. He had obviously been blown across the grass median from the opposite traffic lane. The rain was so intense that I didn't perceive the truck until I was only a few car-lengths away.
