What happens if I get a speeding fine while driving a rental car in Cantón Atenas?
Generally, one of two things will happen. Your chosen rental car company may bill the fined amount to your credit card. This is the usual approach. On the other hand, it may pass on your contact information to the relevant local authority so the fine is sent to you directly.
