Tolls and Discounts

Will there be a discount for Clean Air Vehicles in the 405 Express Lanes?

Customers with a clean air vehicle with a valid decal are eligible for a 15% discount off the posted toll rate. To receive the discount, customers with a clean air vehicle need a valid DMV-issued CAV decal and a copy of the vehicle’s official California DMV vehicle registration.

All vehicles are required to have an interior mounted sticker or exterior mounted sticker transponder.

Other CAV vehicles, including those with legacy yellow (expired 2011), legacy green (expired 2019), white or red decals, will not be eligible to receive any CAV discounts.
