Q: What is a Peach Pass? Where can it be purchased? How much does it cost? And how is the cost of using the lanes determined, and how is it billed?

—Richard Proot, Acworth

A: A Peach Pass is an electronic device on a vehicle windshield or mounted to a bumper or headlamp that automatically deducts toll money when using the Georgia Express Lanes, according to peachpass.com. There are different types of accounts, depending on if you want to use a credit card, a debit card or cash to prepay.

You can sign up for a personal toll Peach Pass account online at mypeachpass.com or by calling 855-724-7277. In-person options are the Peach Pass Retail Center (245 Peachtree Center Ave. NE, Atlanta 30303) or Department of Driver Services locations: 310 Hurricane Shoals NE, Lawrenceville 30046; 619 Tanger Boulevard, Locust Grove 30248; and 3690 Old 41 Highway NW, Kennesaw 30144. You can purchase a Pay n GO! Peach Pass at Walgreens or CVS stores in Georgia.

With the dynamic pricing model, the prices vary depending on the demand. At a minimum, the toll rate is 10 cents per mile, and the toll amount is posted before entering the lanes, according to peachpass.com. During certain off-hours, which are indefinite times, the 10 cents-per-mile rate has a cap and users will not be charged more than 50 cents.
