Does Avis require an IDP in Mongolia?

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 nationwide electronic toll system; a few paved intercity highways (such as sections out of Ulaanbaatar toward the airport and Zuunmod) have manual cash toll booths charging small tugrik amounts. Most of the country is unpaved with no tolls.

Central Ulaanbaatar has paid attended parking lots and metered street bays; pay the attendant or kiosk in tugrik, and illegally parked cars are ticketed or towed. Parking is scarce and chaotic around Sukhbaatar Square and the State Department Store.

The drink-drive limit is a strict 0.02% BAC and default speed limits are 40 km/h in town and 80 km/h on rural roads; police issue on-the-spot fines, often payable in cash. Rental companies pass any traffic or camera fines back to the renter.

Dial 102 for police and 103 for ambulance (the unified 112 is being rolled out). Report any accident to police and leave the vehicles in place until officers arrive, as a police report is needed for insurance and to leave the country.
