Does Alamo require an IDP in Thailand?

Alamo's standard minimum rental age in the US is 21 (18 in Michigan and New York where state law requires it); renters aged 21-24 pay a "young/youthful driver" surcharge that averages about $25 per day but varies by location (for example roughly $13/day in Michigan and $20/day in New York), and under-25 renters may be restricted to certain car classes.

A major credit card in the primary renter's name is required at most locations; debit/check cards bearing a Visa, Mastercard or Discover logo are accepted at airport locations only with a ticketed return travel itinerary (Discover not accepted in Canada), and the name/address on the card and license must match, with a hold placed at pickup that reduces available funds.

Additional authorized drivers typically cost about $15 per day each (around $5/day in New York), and every additional driver must also meet the minimum-age and license requirements; some promotions or contracted/corporate rates waive the fee. Alamo requires each driver to hold a valid, unexpired driver's license; the license must have been issued before the rental and held for the qualifying period, with locations commonly expecting it to have been held for at least 1 year.

Vehicles rented in the US may typically be driven throughout the US and Canada but cannot be taken into Mexico; vehicles rented in Canada may be driven in Canada and the US. Cross-border and one-way rentals must be disclosed and authorized at the counter, and one-way availability and drop fees vary by location.

Alamo states an International Driving Permit cannot be used on its own and the home-country license must always be presented; an IDP is recommended (not required) when the license uses Roman/English letters, but is required when the license is in a non-Roman alphabet (e.g. Russian, Japanese, Arabic), with a typed professional translation as a substitute if no IDP is available.

Bangkok and inter-city expressways (EXAT/DOH) charge fixed-amount tolls payable in cash at booths or electronically via the M-Pass or Easy-Pass transponder/sticker; most short urban expressway segments cost roughly 25-90 THB. Unpaid e-tolls now carry escalating penalties, so use cash lanes if your rental has no tag.

Park only in marked bays; illegal or red-and-white-curb parking draws 200-500 THB fines and towing, common in central Bangkok. Malls and BTS-area lots offer paid garages (often 20-40 THB/hr), and apps/attended lots are the safe option in dense districts.

Speeding typically 1,000-2,000 THB, no-seatbelt and mobile-phone use up to 1,000 THB, and drink-driving over 0.05% BAC is heavily fined or jailed; minor fines are frequently issued on-the-spot in cash at checkpoints. Rental firms pass camera/toll tickets to your card plus an admin fee.

Call 1669 for medical emergency and 191 for police (insurance/tourist accident hotline 1554); for any injury or insurance claim a police report is required. Do not move the vehicles until police or the insurer's assessor arrives unless they are blocking a fast lane and you mark positions.
