Does Hertz require an IDP in Slovenia?
Written by Daniel MercerUpdated July 2026
Hertz in Slovenia: the policy in plain terms
Asks foreign drivers for a licence translation when the licence is not printed in the Roman alphabet, and often for non-EU renters in much of Europe. One of the largest global rental networks, operating in 150+ countries.
Slovenia drives on the right and requires an e-vignette for motorways; non-EU visitors should carry an IDP with their licence.
In Slovenia specifically, many rental companies and local authorities in Slovenia ask foreign drivers to present a translation of their licence alongside the original, so Hertz will typically ask for it at the counter. Ljubljana desks request an IDP for non-EU licences; e-vignette included with rentals.
Hertz runs a global network; at its Slovenia desks, foreign renters are asked for an International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format alongside the original licence. Slovenia drives on the right, uses the EUR, and sets a minimum driving age of 18, so an IDP is the document that removes any doubt at the counter.
What to bring to the Hertz counter in Slovenia
- Your original national driving licence (the IDP never replaces it).
- Your International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format.
- Your passport and a payment card in the main driver's name.
- Local payment for the EUR deposit; Slovenia drives on the right with a young-driver surcharge under 25.
Driving rules in Slovenia Hertz renters should know
- Motorway e-vignette required.
- Headlights on at all times.
- 0.05% alcohol limit; zero for new/professional drivers.

Hertz's rental terms that affect your IDP booking
Hertz's standard minimum rental age in the US and Canada is 20, though it drops to 18 in Michigan, New York and Quebec, and 19 in Alabama and Nebraska. Renters aged 20-24 pay a Young Renter fee of about USD 19 per day, and under-25s are blocked from premium, luxury and high-performance car classes.
Hertz places a hold on the renter's card for the estimated rental charges plus a security deposit that varies by location and vehicle class; debit cards are accepted at many US locations but must be Visa, MasterCard or Discover branded, in the main driver's name, and carry sufficient available funds, with extra ID/credit checks sometimes required.
Hertz charges a per-day additional-driver fee that varies by location (commonly around USD 13.50/day in the US, capped per rental); in many markets a spouse/domestic partner can be added free, and the fee is often waived for Gold Plus Rewards members. Hertz requires each driver to hold a valid full driver's licence that has typically been held for at least one year, with longer tenure (often one to two years) required for some markets and premium vehicle classes.
Driving a Hertz vehicle across a country border (e.g. US to Canada or Mexico) requires advance permission and may incur a cross-border fee, and travel into Mexico generally requires separate Mexican insurance; one-way rentals are permitted on many routes but typically carry a drop-off/one-way charge.
Hertz states that a valid driver's licence issued by the renter's home country must always be presented; an International Driving Permit is recommended (and effectively required) when the home-country licence is not in the Roman alphabet or not in English, but Hertz will not rent on an IDP alone.
Once you collect the keys in Slovenia
All motorways and expressways require an electronic e-vignette for vehicles up to 3.5t, sold by the week, month or year at petrol stations, post offices and border shops; check whether your rental includes one, as driving without it draws an on-the-spot fine up to about EUR 800.
In Ljubljana, white-line zones allow up to 2 hours paid parking 07:00-19:00, with park-and-ride lots on the outskirts; illegal parking costs EUR 80 (EUR 40 if paid within 8 days). Pay via meters or parking apps.
Minor speeding (1-10 km/h over) starts around EUR 50-120, while 30+ km/h over can mean EUR 300-1,200 plus penalty points and licence suspension; police can issue on-the-spot fines and rental firms forward camera fines plus an admin fee.
Dial 112 for emergencies; for any collision you must notify the police and obtain an accident report for insurance, and vehicles should not be moved until documented if there are injuries.
