Does InterRent require an IDP in Grenada?

InterRent in Grenada: 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.
Grenada drives on the left and requires visitors to buy a local temporary permit, arranged through the rental company or police.
In Grenada specifically, many rental companies and local authorities in Grenada ask foreign drivers to present a translation of their licence alongside the original, so InterRent will typically ask for it at the counter. A local temporary permit is required; rental desks help arrange it.
InterRent runs a europe network; at its Grenada desks, foreign renters are asked for an International Driving Permit in the internationally recognised format alongside the original licence. Grenada drives on the left, uses the XCD, 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 Grenada
- Your original national driving licence (the IDP never replaces it).
- Your International Driving Permit in the internationally recognised format.
- Your passport and a payment card in the main driver's name.
- Local payment for the XCD deposit; Grenada drives on the left with a young-driver surcharge under 25.

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 Grenada
There are no toll roads or vignettes; all public roads are free to use.
Parking is informal outside St George's, where street space is tight and metered/attended lots near the Carenage and market are common; park clear of bus stops and blind corners or risk a ticket.
Police issue fines for speeding, no seatbelt and phone use; the urban limit is low (around 30-40 km/h) and fines are modest but rental firms recover any unpaid tickets from your deposit.
Dial 911 for police and ambulance; do not move the vehicles, wait for police to attend, and obtain a police report, which is required for any insurance claim.
