I made a small road trip from Los Angeles to San Francisco during the last 7 days. I only discovered today that there are tolls to pay on some roads, without any barrier to pay (we have to pay online?). I was driving a rental car.
I don't recall the roads I took, so I might need to pay something.
Here are my questions:
How can I know if I took one of those roads? (I don't recall the roads I took.)
How can I pay for them?
Do I risk something for paying them that late?
