Does Thrifty require an IDP in Guinea-Bissau?

Thrifty's published minimum rental age is 20 at most U.S. and Canada locations (18 in Michigan, New York, and Quebec); drivers aged 20-24 (or 18-24 in those exception states/province) are charged an Underage Drivers fee that varies by location, typically around $29/day and higher (roughly $35-$52) in New York and Michigan.

A valid credit/debit card in the renter's own name is required and a hold is placed for estimated charges plus roughly $200 extra for credit cards or $500 for debit (about $350 CAD in Canada); Visa/Mastercard/Discover debit cards are accepted only on Compact through Fullsize classes (not Premium and above) and a physical card must be presented as digital-wallet cards are not accepted.

Additional drivers must meet the minimum age requirement and hold a valid licence, and an additional-driver fee applies per day; it is waived for Blue Chip Rewards members, government renters on official orders, corporate-rate customers, and the companion/driver of a physically impaired customer. Thrifty's general policy requires a valid driver's licence covering the entire rental period but does not publish a fixed minimum tenure; in practice under-25 renters are typically expected to have held a full licence for at least one year.

Driving is generally restricted to the continental United States and Canada, and a Canadian resident is prohibited from driving a U.S.-owned vehicle into Canada; one-way rentals are offered within the U.S. and within Canada subject to location/availability with a one-way drop fee.

Foreign renters must present a driver's licence issued in their country of residence together with a valid passport; if the licence is not in English, Thrifty requires both the foreign licence and a current International Driver's Permit to be presented.

There is no functioning national motorway toll or vignette system; roads are funded publicly and you generally pay nothing to drive, though informal road barriers and checkpoints are common in the interior.

Parking in Bissau is largely informal and unmetered, with self-appointed attendants ('guardadores') expecting a small CFA-franc tip to watch the car; there are no painted paid-zone schemes or parking apps.

Enforcement is mostly by physical police/gendarme checkpoints rather than cameras; fines are usually negotiated and paid in cash on the spot, and the documented drink-drive limit is 0.15% BAC (15 mg/100 ml).

There is no reliable nationwide emergency line; in a serious crash do not move the vehicles if there are injuries, summon the Polícia de Ordem Pública locally and obtain a written police report (auto), which insurers and rental firms require.
