I'm looking into a car rental in Netherlands (Alamo) and their terms and conditions state that:
International Driving Permit needed along with original domestic licence.
Does this also apply to standard format EU licenses? My Czech license only has Czech text, but it does follow the standard field numbering format. I'm looking for a general answer that covers all of the EU - if at least some of the companies ask EU license holders for an IDP, it would be prudent to get one.
Also note that this question isn't about police checks - I am aware that EU members must recognize each other's licenses.
