Getting an electronic tolls pass—such as an E-ZPass or SunPass—to use with your rental car can save you a few dollars on select tolls compared to paying with cash (up to $4.75 when crossing the George Washington Bridge or Lincoln Tunnel in New York), but if you're not hitting the tolls every day you rent the car, it may not be worth it. Some car rental companies charge up to $5 per day for use of the pass—even on days when you never pass a toll plaza. Plus, some advertised discounts come with restrictions. For example, you can cross the Golden Gate Bridge into San Francisco for half price with a FasTrak pass, but to get the full 50 percent off, you must have three or more people in the car and be crossing during weekday rush hour. Otherwise, using FasTrak shaves $1 off the $6 toll. USA Today offers a roundup of many of the major rental car companies' policies so you can check yours at a glance before booking.
