The roads that charge as you go
Hundreds of tolled roads, bridges, and tunnels stretch across the United States, run by more than a hundred independent authorities — each with its own tag, its own rules, and its own way of billing you. This is the reference that keeps them straight.

The vocabulary you need to read the rest of this site.
A small device (E-ZPass, SunPass, TxTag, FasTrak, and others) that a reader detects at highway speed and links to a prepaid account. Most regions honor neighbors' tags through interoperability agreements, but coverage is not yet nationwide.
No booths. Overhead gantries read your tag or photograph your plate, and you're billed automatically. Most new toll facilities open this way; many older ones have converted.
If you have no tag, a camera reads your license plate and mails an invoice to the registered owner — usually at a higher rate than the tag price, plus fees.
On many express lanes the price changes minute to minute with demand, keeping the lane flowing. The posted rate is what you pay when you enter, even if it rises behind you.
Tolled lanes running alongside free general-purpose lanes. Drivers buy out of congestion; carpools often ride free or discounted.
The patchwork of agreements that lets one tag work across agencies. The E-ZPass network spans much of the East and Midwest; the West and South are still consolidating.

Toll roads are operated by independent authorities, state departments and private concessionaires, not a single national agency. Some sell you a transponder; most only read one. Open an agency for its links, the account you would actually need, and the facilities it tolls.
