Does Avis require an IDP in Vietnam?

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 use BOT toll stations; cars pay roughly VND 150,000-200,000 (about USD 6-8) per 100km, and the three e-tag providers (VETC, ePass, VietMap) are now interoperable nationwide, though many booths still take cash. A rental car should ideally have an e-tag fitted, as some expressway lanes are becoming barrier-free electronic-only.

In Hanoi and Ho Chi Minh City use guarded paid lots (gui xe) at hotels, malls and street attendants who issue a ticket for a small fee; do not leave a car unattended on the street. Pavement and red-curb parking is routinely ticketed or clamped in the central districts.

2025-2026 reforms raised fines sharply: phone use while driving is now VND 4-6 million, and extreme/reckless driving can reach VND 50 million (about USD 1,900); alcohol limit is effectively zero. Police can fine on the spot, and rental firms pass camera (phat nguoi) fines back to the renter's card.

Stop immediately, do not move the vehicles, and call police on 113 (ambulance 115); leaving the scene of an injury crash is a serious offence. Wait for police to produce a report for your insurer/rental firm, and expect to be detained until fault is settled, especially in injury cases.
