Peru Driving Rules for Americans (2026 Guide)
Peru drives on the RIGHT. Urban limit is usually 40-60 km/h and highways up to 100 km/h. Police (PNP) enforce seatbelts, phone use, and a 0.05 BAC limit — and you must carry an International Driving Permit with your US license.
Signs are in Spanish (Quechua in parts of the Andes). Altitude affects both you and the car above 3,000m.
Which Side of the Road Does Peru Drive On?
Peru drives on the right-hand side of the road, the same as the United States, with the steering wheel on the left. That removes the biggest adjustment US drivers face in places like the UK or Japan — but Peru makes up for it with altitude, aggressive city traffic, and mountain roads.
You still need an International Driving Permit (IDP) alongside your US license. It is a translation of your license into multiple languages and is what makes your US credential recognizable to Peruvian police and rental agencies.
Peru Speed Limits (with MPH Conversions)
Limits are posted in kilometers per hour. These are the standard defaults; always follow posted signs, which override the general limits — especially in school zones and through towns on the Panamericana.
| Road Type | Limit (km/h) | Approx. mph |
|---|---|---|
| Residential / school zones | 30 | ~19 |
| Urban streets | 40-60 | ~25-37 |
| Urban expressways (e.g. Lima) | 60-80 | ~37-50 |
| Rural highways | 80-90 | ~50-56 |
| Main highways (Panamericana) | 100 | ~62 |
On mountain roads your safe speed is often far below the posted limit. Switchbacks, fog, rockfall, and slow trucks mean you should treat posted numbers as a ceiling, not a target.
Police and How Enforcement Works
Traffic enforcement in Peru is handled primarily by:
- PolicĂa Nacional del PerĂş (PNP): The national police, including a traffic division (PolicĂa de Tránsito), who staff highway checkpoints and city patrols.
- Municipal transit police / inspectors: Handle parking, city traffic control, and some local enforcement in Lima and other cities.
- SUTRAN: The national transport oversight body that runs highway controls and weigh/inspection points.
Enforcement mixes fixed and mobile speed cameras, red-light cameras in Lima, and in-person document checkpoints on the Panamericana and at city entrances. Expect to be asked for your passport, US license, IDP, and rental papers at a stop. Always ask for an official citation (papeleta) for any fine and never hand over cash informally.
Drunk-Driving Limit and Penalties
Peru's general blood-alcohol limit is 0.05% BAC (0.5 g/L). Penalties escalate quickly and can include:
- Fines commonly in the S/ 1,070-2,140+ range (roughly $290-580) for exceeding the limit.
- License suspension or, for a foreign driver, being barred from continuing to drive.
- At higher levels, driving under the influence can be treated as a crime, not just a traffic offense.
Given the stakes, altitude (which can amplify alcohol's effects), and the difficulty of handling a legal problem abroad, the only safe policy for a visitor is zero alcohol before driving.
Mandatory Equipment and Behavior
- Seatbelts: Required for the driver and passengers. Rear-seat belt use is increasingly checked.
- Child restraints: Young children must ride in an appropriate seat and generally not in the front.
- Phone use: Handheld phone use while driving is prohibited and fined. Mount your phone and set your route before moving.
- Safety kit: Rentals should carry the legally required items such as a warning triangle, reflective vest, fire extinguisher, and a basic first-aid kit. Confirm they are in the car at pickup.
- SOAT: Every vehicle must carry mandatory accident insurance (SOAT); it is included with rentals but you should verify the document is in the glovebox.
- Motorcycle helmets: Required for riders and passengers.
Key Spanish Road Signs for Americans
Signs are in Spanish and mostly follow international symbols, but a few words trip up US drivers. Learn these before you go:
| Sign (Spanish) | Meaning |
|---|---|
| PARE | Stop |
| CEDA EL PASO | Yield / give way |
| DESVĂŤO | Detour |
| NO ADELANTAR | No passing / no overtaking |
| PROHIBIDO ESTACIONAR | No parking |
| SENTIDO ĂšNICO | One way |
| PEAJE | Toll booth ahead |
| ZONA DE DERRUMBES | Rockfall / landslide zone |
| REDUCTOR DE VELOCIDAD | Speed bump |
Right-of-Way Conventions
- No turn on red: Unlike much of the US, you generally may not turn right on a red light in Peru unless a sign specifically permits it.
- Roundabouts (Ăłvalos/rotondas): Traffic already in the circle usually has priority, but in practice assertive local driving means you should be cautious and make your intentions clear.
- Unmarked intersections: In theory the vehicle on the right has priority, but do not assume others will yield — treat every uncontrolled junction defensively.
- Pedestrians: Legally they have rights at crossings, but jaywalking is common and drivers often do not stop, so watch carefully in cities.
- Horn use: The horn is used constantly as a communication tool (“I'm here,” “I'm passing”), not as an insult. Do not take it personally.
Altitude Driving, Tolls, and Peru-Specific Rules
- High altitude: Cusco is around 3,400m (11,150 ft) and many passes exceed 4,000m. Altitude sickness (soroche) can impair your judgment, and engines lose power. Acclimatize, drive slowly on climbs, and avoid long high-altitude days right after arrival.
- Tolls (peajes): The Panamericana and other main routes charge tolls. Keep small soles in cash; card acceptance is inconsistent at some booths.
- Night driving: Strongly discouraged on rural and mountain roads — many are unlit, animals stray onto the road, and remote stretches carry a robbery risk. Plan to arrive before dark.
- Lima traffic and combis: Expect aggressive lane changes and informal minibuses (combis) that stop and cut across without warning. Segregated bus lanes (like the Metropolitano) are off-limits to private cars.
- Headlights: Use them in tunnels, fog, and at dusk; carry the vehicle documents and your IDP at all times.
Understanding these conditions matters as much as the written rules — the road environment, not the rulebook, is what challenges most American drivers in Peru.
