Does Avis require an IDP in Yemen?

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 developed motorway or electronic toll network; long-distance routes instead pass through numerous military and tribal checkpoints where informal payments or document checks, rather than formal tolls, are the norm. Carry cash and copies of your IDP, passport and any travel permits at every checkpoint.

There are no organised paid parking zones or apps; in Sana'a and Aden you simply park on the street, ideally in a guarded hotel compound or where an attendant watches the car for a tip. Vehicle theft and carjacking are real risks, so never leave a car unattended in an unsecured spot.

Formal traffic-fine enforcement is weak and inconsistent amid the conflict; the bigger risks are detention or fines at checkpoints for missing permits, and a strict nationwide alcohol ban means any drink-driving is treated severely. Do not photograph checkpoints, police or military.

Stop and do not move the vehicles; there is no reliable single emergency line nationwide, so contact local police or the nearest checkpoint/military post, which often handle incidents. Obtain whatever written report you can for insurance, and be aware that injury crashes can trigger tribal blood-money (diya) claims that are settled locally.
