Does Alamo require an IDP in Chile?

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.

Santiago's urban autopistas (Costanera Norte, Vespucio, etc.) are free-flow and require a TAG transponder, which by law all Santiago rental cars now carry; intercity highways (Ruta 5) use manned plazas where many lanes take only Chilean peso cash.

In cities use signed paid street zones (parquímetro, often via attendants/apps) or guarded lots; informal 'cuidadores' watch parked cars for a tip. Heed no-parking signs as towing and clamping occur in central Santiago.

Speed and red-light cameras are common; serious speeding and drink-driving are court matters with heavy fines. Carabineros do roadside checks; fines are not paid in cash to officers, and camera/photo infractions are billed to the renter via the rental agency.

Call Carabineros on 133 (ambulance 131); do not move vehicles if anyone is injured. Report the crash, give names, plate numbers and time/place, and obtain the constancia for insurance and the rental company.
