Planning Tips

Carry extra water — summer heat in the car and at rest stops dehydrates faster than you think.
Start drives early or late to avoid peak afternoon heat, especially through desert or plains stretches.
Check your tire pressure before long summer drives — hot pavement increases blowout risk with underinflated tires.
