AutoExpreso is an electronic toll collection system used on tollways in the United States territory of Puerto Rico.^[1] The system uses passive transponders^{[citation needed]} where payment status is indicated by a light at the toll plazas. In 2012, AutoExpreso became the exclusive form of payment on most of Puerto Rico's tollways, with cash no longer being accepted.^{[citation needed]} However, until 2015, cash was still accepted on PR-5 and PR-22 due to the privatization of those tollways.^{[citation needed]}

In addition to window transponders, a card form of AutoExpreso known as MóvilCash is also available.^{[citation needed]} AutoExpreso is not interoperable with other electronic toll collection systems outside Puerto Rico (such as E-ZPass in the northeastern United States or SunPass in Florida).
