Does InterRent require an IDP in Trinidad and Tobago?

InterRent in Trinidad and Tobago: 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.
Trinidad and Tobago drive on the left and accept a valid foreign licence for short stays; an IDP is advised for non-English licences.
In Trinidad and Tobago specifically, trinidad and Tobago lets visitors drive on a valid foreign licence, but InterRent still asks for a licence translation if your licence is not printed in the Roman alphabet — and it removes any doubt at the counter. Port of Spain desks accept English licences; an IDP helps non-English drivers.
InterRent runs a europe network; at its Trinidad and Tobago desks, foreign renters are asked for an International Driving Permit in the 1949 Geneva Convention format alongside the original licence. Trinidad and Tobago drives on the left, uses the TTD, and sets a minimum driving age of 18; an IDP is still the safest way to avoid a refused booking.
What to bring to the InterRent counter in Trinidad and Tobago

- Your International Driving Permit in the 1949 Geneva Convention format.

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 Trinidad and Tobago
There are no toll roads in Trinidad and Tobago; the Uriah Butler, Solomon Hochoy and Churchill-Roosevelt highways are all free, with congestion rather than tolls being the main concern.
Central Port of Spain has metered and paid lots but very tight, congested kerbside space; downtown and Charlotte Street areas see vehicle break-ins, so use guarded car parks and never leave valuables visible.
From 1 January 2026 fines doubled: speeding ranges from TT$2,000 (1-9 km/h over) up to a TT$6,000 fixed penalty for 31 km/h or more, with heavy seatbelt, phone and DUI penalties; rental firms charge any camera tickets back to the hirer.
Call police on 999 (emergency 990 for fire/ambulance); report the accident to the Trinidad and Tobago Police Service (online or at a station), do not move vehicles when there are injuries, and exchange insurance details.
