A Snow Squall Can Turn Into a Pileup in Seconds. Here's How to Survive One.

A snow squall isn’t a “cute little flurry.” It’s a fast-moving blast of snow that can turn clear pavement into a whiteout in minutes. Visibility drops hard. Roads ice over fast. The danger is the speed. Drivers roll in at normal highway pace and hit a wall of zero vision.

The National Weather Service says snow squalls can be life-threatening because they combine heavy snow, gusty wind, and sudden loss of visibility. That mix can trigger pileups fast, especially on interstates and bridges.
