# Editorial policy

CarHire ES compares car hire offers in Spain. This page explains where the facts in our guides and city pages come from and how often they are updated.

## Where the facts come from

- **Prices and availability** - the catalogue of our partner Localrent, updated once a day for 123 cities and airports.
- **Deposit, excess, insurance, payment and cancellation** - the terms of the rental company shown in the car card and in the voucher.
- **Road rules, fines and low-emission zones** - official sources: DGT (the Spanish traffic authority), the Official State Gazette BOE and city council websites.
- **Driving licence and international driving permit** - government sources and national automobile clubs for each of 108 countries.

If a figure cannot be confirmed, we do not publish it. The text then says where to see the exact value - usually the car card.

## How pages are kept up to date

- Prices in page titles and tables are recalculated once a day.
- Each guide shows its publication date and the date of the last update. The update date changes whenever the text is edited.
- When a rule changes - a new low-emission zone, a different fine - we update the pages it affects.

## How we make money

When you book through our link, the rental company or our partner pays us a commission. Your price does not change. Details are on the [About us](https://carhire-es.com/about/) page.
