Is an international driving permit mandatory?
Legal framework:
An International Driving Permit (IDP) is mandatory. This country accepts the 1949 Geneva Convention (1-year validity) and the 1968 Vienna Convention (3-year validity).
Rules of conduct in Peru
Speed limit: 50 km/h in town, 90 km/h on national roads and 100 km/h on the Panamerican Highway.
Blood alcohol level: the legal limit is 0.5 g/l.
Speed controls (Sutran) are common on major roads. In the event of a serious injury or material accident, it is prohibited to move the vehicles before the arrival of the police to establish the report (Atestado).
Tips from easy-idp.org
"Driving is on the right.
In Lima, traffic is chaotic, congested, and courtesy rules are rare: "Combis" (public transport minibuses) stop abruptly and pull out without signaling.
The use of the horn is intensive there.
Outside major cities, the Andes Mountains offer spectacular but dangerous roads (narrow, winding, prone to landslides, often without guardrails).
In the mountains, the unwritten rule is to honk before every blind turn.
Prefer long-distance buses (Cruz del Sur, Oltursa) over car rental to travel across the country."
