I want to pay my Golden Gate Bridge toll using a rental vehicle

Bridge the wires at the switch located at the door/lift gate which signals that the door/lift gate is open/adjar

need to notify the toll authority this is fixya

not a technical problem for fixya site
call the toll operators direct by phone and ask them

If you paid them on a toll transponder in your car, you could get a receipt then from your toll company.

If you paid cash I don't see any way to prove it.
Hope this helps.

you know they never get done painting the golden gate bridge, they just start over as soon as they are done. that airbag system was designed to make it 3 years. you are going to be replacing one part after another etc. it is too complex with too many parts subject to vibration and weather. consider getting another car with springs and shocks or replacing the whole system with a regular suspension from strutmasters.com.
