How is the toll on the Spanish highway charged ?

Fee standards: Spanish highways are mainly divided into two types: toll AP highways (Autopista) and toll-free A highways (Autovia). The AP highway charges approximately 1 euro every 10 kilometers. Payment methods: There are multiple ways to pay for tolls on Spanish highways: 1. No ticket is needed, and a fixed amount is collected directly at the end of the highway, similar to toll stations on domestic highways. 2. Taking a card when entering the highway, there are three ways to pay when exiting the highway: 1) Self-service payment channel: Insert the highway ticket into the card slot of the toll machine (marked with TICKET), the screen will display the toll amount. You can pay with coins, banknotes, or a bank card, and then the machine will print a transaction voucher for you to pass through. 2) Manual toll channel (marked with MANUAL): Service personnel collect tolls and accept cash. 3) Automatic toll channel: Similar to ETC in China. If you accidentally enter the ETC channel, do not forcefully change lanes to avoid accidents. You can press the call button next to the ETC for manual service. Note: Some highway exits only accept coins, while others only accept credit cards with chips. Therefore, it is best to prepare both change and an international credit card with a chip before entering the highway.
