Does Avis require an IDP in Sri Lanka?

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.

Expressways (E01 Southern, E03 Airport, E02 Outer Circular) are tolled with cash booths and the contactless 'TAGRush'/expressway pass; tourists typically pay cash, with charges of a few hundred to roughly LKR 1,000+ depending on distance.

Urban parking in Colombo and tourist towns is largely paid on-street with attendants/wardens collecting cash, plus private and mall lots; unattended or restricted-zone parking can be ticketed or wheel-clamped.

Police issue on-the-spot fines (spot-fine slips paid later at post office or now via online/eRL channels) for speeding, no seatbelt and mobile-phone use; tourists driving without a valid Recognition Permit risk prosecution and rejected insurance claims.

In any injury accident you must stop, not move vehicles, and call Police on 119 (ambulance 1990 Suwa Seriya); a police report is needed for insurance, and driving without the Recognition Permit can void your claim and lead to prosecution.
