With extreme heat and rising humidity expected across the state, the Illinois Department of Transportation is warning drivers to watch out for pavement blowouts.

Pavement blowouts happen when long stretches of high temperatures cause roads to expand and buckle or crack, creating hazardous driving conditions. Humidity and rain can make the problem worse.

If you see a pavement issue while traveling, you’re encouraged to report it to IDOT by calling 800-452-4368, or by contacting local law enforcement through 911.

IDOT also reminds drivers to take precautions when traveling in the heat, especially to carry water. If your vehicle breaks down, dehydration can happen fast and pose a serious risk.

You can learn more about how pavement blowouts occur by watching an informational video on IDOT’s website.
