The Leak: Using Cash to Pay Tolls
The fix: Sign up for an electronic toll device, such as E-ZPass (ezpass.com), which is now good on a number of toll roads, bridges, and tunnels in 13 states from Illinois to Maine; FasTrak in California; SunPass in Florida; or PikePass in Oklahoma. You'll save time and fuel by not idling in toll lanes, and some toll roads offer regular commuters discounts of as much as 50 percent. The International Bridge, Tunnel, and Turnpike Association (ibtta.org; click on "Information & Resources," then "Toll Rates") lists websites for local toll authorities and their discount details.
Savings: 15 to 50 percent per trip.
