Why are Nevada roads so hard to drive on in the rain?

Rainy roads in Washoe Valley on May 16, 2018 by Kristina Brimm

If you've ever driven in the rain anywhere else but Nevada, you may have noticed that our roads are much harder to drive on in wet weather than other places. As it turns out, there's a few reasons for that.

The first is that we sometimes go a long time without wet weather, so some of the oils and fuels that leak from cars over time become slick once we see rainfall.

But the main reason our roads are so much more challenging to drive on is actually because of the way they're built -- without a drainage layer.

Most roadways have a layer at the surface of their roads that allows some water to drain through the road and into ditches. We can't build that layer in Nevada because our temperatures fluctuate too much -- when our temperatures drop below freezing, the water below the surface could freeze and crack the roadways.
