A private vehicle you drive as a disabled veteran does not have to pay tolls on ferries or bridges, or fees at parking facilities the state owns or operates. The exemption does not cover the Crescent City Connection bridges or ferries.
There is nothing to apply for. Carry your proof of disabled veteran status and show it when you are asked to pay. A Disabled Veteran license plate or the disabled veteran designation on your license makes this easier.
Your VA disability documentation, or a Louisiana Disabled Veteran license plate or disabled veteran designation on your driver’s license.
