When in line at the counter, never allow anything to distract you from your possessions. As soon as you enter the car lock your doors and keep them locked. Keep your windows closed while driving in slow moving traffic. Keep valuables, such as your briefcase or purse, out of sight as someone could smash your window and steal them. If you have a flat tire, call for assistance or drive to a safe location to replace it even if you might ruin the tire or wheel.
Many rental vehicles have phones.
Dialing 911 from a car phone is free. If you are bumped by another vehicle, don't stop on the highway. Signal the other driver to follow you to a safe, populated area or police station before getting out of your car. Express check-in saves time Enroll with your favorite car rental company. Having a profile with them will allow you to bypass the counter and get on with your business without delay.
