Does Avis require an IDP in Montenegro?

Avis's standard minimum rental age is 25, though it rents to drivers as young as 21 in most US states/provinces (some locations require 25 by local law); renters aged 21-24 pay a young-driver surcharge of roughly $25 per day in the US (about $35/day in Canada).

Avis requires an Avis-honored credit or charge card (Visa, Mastercard, Amex, etc.) and places an authorization hold covering the estimated charges plus a security amount; Visa/Mastercard debit cards are accepted at most US locations but are subject to stricter checks, and the card must be in the renter's name.

Additional drivers must be at least 25 (or meet the underage rules) with a valid licence and typically cost about $13 per day, capped near $65 per rental; in California the fee is waived for a spouse, parent, sibling or child of the renter. Avis requires a valid driver's licence held for the entire rental period that is not suspended, expired, revoked, cancelled or surrendered; it does not publish a fixed minimum holding period in the US, though some international locations require the licence to have been held for 1-2 years.

Avis generally permits US-to-Canada travel if the renting location is notified in advance, but driving into Mexico is restricted (typically corporate accounts only, no one-way, and Mexican insurance purchased through Avis from border states); one-way rentals are offered with a drop-off charge that may apply on certain rates.

Avis states that "International Driver's Permits are valid only if presented with the original local license. An International Driver's Permit is not acceptable by itself." Foreign licences are accepted if the issuing country participated in the 1949 Geneva Convention on Road Traffic or has a reciprocal agreement with the US; non-Roman-alphabet licences effectively require an IDP, and renters with a foreign licence may need to present a passport.

There is no vignette; tolls are paid per use, chiefly the Sozina tunnel on the Bar-Podgorica route (about EUR 2.50-3.50 for a car) and the new Bar-Boljare motorway, payable by cash or card at booths.

Paid zones operate in Podgorica, Kotor, Budva and other towns at roughly EUR 0.50-1 per hour, often via attendant, meter or SMS. Coastal old towns like Kotor are largely pedestrianised, so use peripheral car parks to avoid towing.

Police frequently enforce speeding and tunnel overtaking (notably inside Sozina) with on-the-spot fines typically starting around EUR 30-60; phone and seatbelt offences are also fined. Rental firms recharge camera/police fines to the renter.

Call 112 for police and ambulance. By law you must not move the vehicles before police attend and document the scene; an official police report is mandatory for any insurance or rental-damage claim.
