Driving in extreme temperatures

Arizona Department of Transportation tips for driving in extreme temperatures include:

Have sun protection: In addition to an umbrella, take sunscreen, a wide-brimmed hat, and wear loose-fitting, light-colored cotton clothing.

Refuel: Keep your tank three quarters full. Running out of fuel can be dangerous in extreme heat, especially in remote locations.

Hydrate: Bring a cooler to keep extra drinking water cold, and consider adding several frozen bottles of water to cool or thaw and drink as needed. Make sure everyone, including pets, stays hydrated.

Get help: If your vehicle breaks down in extreme heat, call for help immediately to shorten the waiting time and run the air conditioning. If the air conditioning isn't working, roll down all the windows.

Wait for sure: If the temperature inside your vehicle becomes too high, everyone, including pets, should exit carefully and seek or create a shaded area as far away from traffic lanes as possible. Be careful when walking on the pavement as it can be hot enough to cause skin burns. Keep your shoes on and try to keep your pets' paws off the sidewalk. If you are stopped on the highway, raise the front hood and turn on the hazard lights. Please remember that parking in high bushes can cause a fire.

Check your vehicle: You can help prevent breakdowns and flat tires by ensuring your vehicle is in good operating condition. Check your air conditioning and coolant levels, top off all essential engine fluids, and make sure your battery is up to date. Check your tire pressure as the combination of under-inflation and hot pavement can cause a blowout.
