Q&AZ: What to know before a road trip in the Arizona summer heat

If you’re hitting the road this Memorial Day weekend, expect delays due to heavier traffic. But the Arizona Department of Transportation says there are no full highway closures planned in the Phoenix and Tucson areas.

ADOT spokesperson Doug Nintzel says drivers should still be aware of unexpected closures in response to crashes or other incidents.

"You need to be prepared for things such as blowing dust and you need to check on the forecast no matter where you're going to be driving. And then of course it's important to bring an emergency travel kit," Nintzel.

He says that travel kit should include items like extra drinking water, a first-aid kit, flashlight and extra batteries.

ADOT is also encouraging drivers to avoid stopping in areas with grasses or brush since a hot car could start a fire.

ADOT tips

Be prepared for changing weather conditions, including blowing dust. More information about traveling in hot weather is available on the ADOT website. Other holiday weekend and summer travel safety recommendations include:

  • Avoid distractions. Don’t text while driving. Eyes up, phones down.
  • Check your vehicle, including tire pressure and engine fluid levels.
  • Get some rest before traveling. Fatigue is a serious safety risk.
  • Never drive while impaired. Buckle up and obey speed limits. 
  • Arrange for a designated driver or ride service if necessary.
  • If towing a trailer, secure chains so they are not dragging on pavement and creating sparks that might start a brush fire.
