Terms of use
Last updated: 2026-08-18
1. Independent service
Diodiometro is an independent trip cost calculator. We are not affiliated with any motorway operator, ferry line, or public authority.
2. Toll fare accuracy
Prices are sourced from official published tariffs and updated regularly. Concessionaires may adjust rates at any time. The authoritative fare is always the price displayed at the toll barrier.
3. Route planning
Routes are generated using OpenStreetMap data. This tool provides cost planning estimates and does not replace live in-car GPS navigation systems.
4. Disclaimer of liability
This service is provided "as is" without warranty. We assume no liability for discrepancies between estimated and actual expenses incurred.
5. Data usage
The site and its data are freely accessible. Please note that prices and routes may not always be completely accurate or up to date; therefore, automated data scraping is not recommended, and consulting the primary sources of the motorway operators is strongly advised. Map data is provided by OpenStreetMap under the ODbL license.
Prices and times are estimates and can be wrong. For the driving itself, trust a proper navigation provider.
