Orange County, CA toll roads: Here’s what you need to know with the recent switch to sticker transponders

This year, Orange County’s toll roads – the 73, 133, 241 and 261 – have gone through probably the biggest changes since the pay booths went dark in 2014.

Users have been receiving a bandage-sized FasTrak sticker in the mail to replace their ubiquitous hard-cased transponders. Discounts have changed. And every car now must sport a license plate with unique numbers.
