Car Rental in Asuncion (2026) - Driving Guide & Best Rates
Car rental in Asuncion: compare rental companies, daily costs, driving rules, parking tips, and road conditions for self-drive travel in Paraguay.
Driving Requirements
Paraguay generally recognizes foreign driving licenses for visitors during their authorized stay (typically up to 90 days for tourist entry). An International Driving Permit (IDP) paired with your home-country license is strongly recommended if your license is not in Spanish or does not use Latin script, as traffic police may not accept an unrecognized foreign document alone. Rental companies in Asunción commonly require both the original license and an IDP for non-Spanish-language licenses as a company policy, separate from the legal question.
Paraguay's legal minimum age to hold a driving license is 18. Rental company minimums vary by provider: some agencies rent from age 21, while others set the threshold at 25 and may apply a young-driver surcharge for renters under 25. Confirm the specific age policy with your chosen rental company before booking, as this is a rental policy, not a uniform legal mandate.
Paraguayan law requires all vehicles to carry the SOAT (Seguro Obligatorio de Accidentes de Tránsito), a compulsory liability policy covering injury to third parties. Rental vehicles are legally required to carry this coverage, so it will be included in any legitimate rental. Rental companies also offer optional collision damage waiver (CDW) and theft protection products on top of the legal minimum. These are rental company add-ons, not legal mandates. But declining them leaves you financially exposed for damage to the rental vehicle.
Rental companies in Asunción typically require a valid credit card in the driver's name to pre-authorize a security deposit at pick-up; debit cards and cash are generally not accepted for this purpose, though policies vary by company. The pre-authorization amount can be substantial and will temporarily reduce your available credit limit, so check with your card issuer about foreign transaction holds before travel. This is a rental company policy, not a legal requirement.
Paraguay drives on the right side of the road. At unmarked intersections, common in residential areas of Asunción, vehicles approaching from the right have legal priority, a rule that catches many visitors off guard. Mobile phone use while driving is prohibited by law; hands-free use is the legal standard. Asunción's city centre experiences heavy congestion during peak hours, and some central lanes may be restricted to buses or taxis at certain times, so watch for signage indicating lane-use restrictions.
Helpful Tips
Asunción's main airport, Silvio Pettirossi International (ASU), sits in the suburb of Luque, east of the city center, picking up there is convenient on arrival and avoids a separate transfer, though most agencies apply an airport surcharge; city-center offices generally offer lower base rates if you can arrange your own transport in.
Before accepting the car, photograph every panel, the windshield, and the wheel rims, and make sure all damage is noted on the rental agreement, road surfaces in Asunción vary considerably, with potholes common on secondary streets, so confirm with the specific agency whether their CDW covers tire and underbody damage, as this exclusion is not universal.
Both Google Maps and Waze provide solid coverage across central Asunción and the main intercity routes; Waze tends to reflect real-time traffic conditions better on the city's busier corridors and is widely used locally, so it is a practical primary choice, download an offline map as a backup for areas where mobile data can be patchy.
Most agencies operate on a full-to-full fuel policy, return the tank at the same level you received it to avoid agency refueling charges, which are typically higher than pump prices; Paraguay's pump prices are generally lower than in neighboring Argentina or Brazil, and petrol stations are plentiful throughout the city and on major routes.
Metered street parking operates in the microcentro during business hours, and informal parking attendants ('cuida coches') are a common feature across the city, a small tip is the accepted norm. For secure options, shopping centers such as Shopping del Sol offer covered parking and are a reliable choice for daytime errands or when staying nearby overnight.
Driving Warnings
Asuncion's streets are studded with speed bumps (locally called *lomadas*) that are frequently unpainted, unsigned, and placed even on faster-moving roads, visiting drivers regularly damage suspensions by approaching them at normal road speed, so slow down whenever you enter a residential block or see oncoming cars braking without an obvious reason.
Traffic police conduct routine document stops throughout the city; Paraguayan law requires drivers to carry their original license, vehicle registration (*cédula verde*), and valid proof of insurance (*seguro obligatorio*) at all times, driving without these documents can result in on-the-spot fines and, in some cases, vehicle impoundment until paperwork is produced.
Avenida Mariscal López, the city's main north-south corridor, and the streets converging on the Centro histórico become severely gridlocked during weekday morning rush hours (roughly 7, 9 am) and evening peak hours (5, 7 pm), often adding 30, 45 minutes to cross-city trips, plan arrivals and departures outside these windows whenever possible.
During the rainy season (October through March), heavy downpours can flood low-lying streets near the Río Paraguay waterfront and in parts of the Centro within minutes. Driving into standing water risks stalling the engine and obscures deep potholes, so avoid underpasses and riverside roads after intense rainfall until water levels visibly recede.
