Does InterRent require an IDP in Slovenia?
Written by Daniel MercerUpdated July 2026
InterRent in Slovenia: the policy in plain terms
Asks for a licence translation for non-EU and non-Roman-alphabet licences across its European locations. Europcar's value brand for leisure travellers in Europe.
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 InterRent will typically ask for it at the counter. Ljubljana desks request an IDP for non-EU licences; e-vignette included with rentals.
InterRent runs a europe 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 InterRent 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 InterRent renters should know
- Motorway e-vignette required.
- Headlights on at all times.
- 0.05% alcohol limit; zero for new/professional drivers.

InterRent's rental terms that affect your IDP booking
InterRent's minimum rental age is typically 19-21 depending on country (19 in Spain, 21 in the UK and France), and drivers aged roughly 21-24 (24 and under in some markets) pay a young-driver surcharge that varies by location, for example around 8.50 EUR/day (max ~93 EUR) in Spain, 12.95 EUR/day (max ~181 EUR) in France, and about 35 GBP/day (max ~350 GBP) in the UK; some vehicle categories require drivers to be over 25.
A refundable security deposit is pre-authorised (held, not debited) on the main driver's credit card at pick-up; the card (Visa or Mastercard, sometimes Amex) must be in the main driver's name with an expiry date after the return date, and debit cards are not accepted because their rules do not fit InterRent's deposit policy.
Additional drivers must present their own valid driving licence at the counter and sign the rental agreement at pick-up; InterRent charges an extra-driver fee per day that varies by location, though it is frequently included in promotional/package rates. The main driver must have held a full, valid driving licence for a minimum of 12 months (one year) prior to picking up the vehicle.
Cross-border travel and one-way rentals are restricted and must be authorised in advance; cross-border fees and one-way drop-off charges apply and vary by route, with certain countries (typically higher-risk or non-EU destinations) excluded entirely under the rental conditions.
InterRent requires a full, valid driving licence held for at least 12 months; for licences not written in the Latin/Roman alphabet (or otherwise not understandable to the rental agent), an International Driving Permit (IDP) must be presented alongside the original national licence, as the IDP is a translation and never replaces the physical licence.
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.
