Paraguay is a beautiful, deeply authentic, and often overlooked South American destination. However, it is not a place where you can shrug off local regulations. Police officers—particularly the highway patrol—regularly stop drivers, and tourists who seem unaware of the rules are prime targets for fines. To ensure your trip remains memorable for the right reasons, you need to know exactly what crosses the line legally and culturally.
The "Big Red Line" (The #1 Strict Rule)
Zero Tolerance for Drug Possession and Trafficking. While some South American countries have relaxed their stances on personal use of certain substances, Paraguay maintains extremely harsh anti-drug laws. Do not let the relaxed, slow-paced culture fool you. Being caught with even a small amount of illegal narcotics will not result in a slap on the wrist; it leads to immediate arrest, heavy fines, and severe prison time. Paraguayan prisons, such as the notorious Tacumbú, are severely overcrowded and dangerous. Never agree to carry packages across the border for strangers, especially when crossing into Brazil or Argentina.
Traffic & Scooter Rules (The Tourist Trap)
Driving in Paraguay requires extreme defensive driving skills and exact paperwork. The Patrulla Caminera (Highway Police) are infamous for setting up random checkpoints, and they love pulling over tourists.
To avoid steep fines or your vehicle being impounded, you must carry an International Driving Permit (IDP) alongside your home country's driver's license, your physical passport, and the vehicle's insurance documents (Carta Verde if crossing borders). If you rent a scooter or motorcycle, wearing a securely fastened helmet is strictly enforced by law—for both the driver and the passenger. Furthermore, Paraguay has a strict zero-tolerance policy for driving under the influence (DUI). Even one beer will put you over the legal limit, resulting in arrest.
Before hitting the road, make sure you can access live GPS routing to navigate around hazards. We highly recommend reading our guide on How to Get Internet in Paraguay: Airport & Local SIM, eSIM, Wi-Fi so you don't get lost in areas without cell service.
Substance Regulations (Vaping, Alcohol & Meds)

Is Vaping Legal?
Yes, vaping is legal in Paraguay in 2026, but it is classified similarly to traditional tobacco. You cannot vape in indoor public spaces, restaurants, or public transport. Stick to vaping outdoors in designated smoking areas to avoid fines.
Alcohol Restrictions
The legal drinking age in Paraguay is 20, which is higher than in many neighboring countries. While public drinking (like sharing a beer on a sidewalk) is relatively common and socially accepted in many neighborhoods, there is a strict "Ley Seca" (Dry Law) enforced during national and local elections. During this period (usually starting 12 to 24 hours before polls open), the sale and public consumption of alcohol are strictly banned. Additionally, if you are bringing your own liquor into the country, check out the Paraguay Airport Customs Rules: Alcohol, Limits & Fines to ensure your bottles don't get confiscated at the border.
Medicine & Drugs
Over-the-counter medication is widely available, but if you require prescription drugs (especially ADHD medication or strong painkillers), you must carry them in their original, clearly labeled bottles along with a signed and stamped doctor's prescription. Without proof of prescription, custom agents may classify certain medications as illegal narcotics.
Weird & Niche Laws
-
You Must Carry Physical ID at All Times: By law, you are required to carry your official identification (your physical passport, not just a photocopy) at all times. Police can stop you on the street and demand identification; failing to produce it can result in being detained until your identity is verified.
-
The "Ley Seca" Electoral Ban: As mentioned, do not try to buy or openly consume alcohol the day before or the day of an election. Supermarkets will physically tape off the alcohol aisles.
-
Strict Photography Bans: It is illegal to photograph military installations, police stations, and certain government buildings. When in doubt, put your camera away.
Cultural Taboos (Don't Be Rude)
-
Never Mess with Tereré Etiquette: Sharing tereré (a traditional cold herbal infusion) is the cornerstone of Paraguayan social life. If you are invited to partake, drink the entire cup handed to you before passing it back to the server. Never wipe the bombilla (metal straw) with your hand or shirt before drinking; it is considered incredibly rude and implies the host is dirty.
-
"Hora Paraguaya": Punctuality is viewed as a loose suggestion. If invited to a social gathering at 8:00 PM, showing up before 8:45 PM will likely mean you are the only one there. Be patient and adjust to the local rhythm.
-
Dress Modestly in Rural Areas: While Asunción is modern, rural towns and religious sites remain conservative. Avoid wearing extremely revealing clothing, beachwear, or going shirtless off the beach/poolside, especially when visiting the Jesuit Missions or local churches.
Stay Connected to Stay Safe
In Paraguay, having immediate access to the internet is a vital safety tool. You need it to translate Spanish or Guaraní during police stops, double-check official regulations on the Secretaría Nacional de Turismo (SENATUR) website, and book secure rideshares (like Uber or Bolt) to avoid unmetered, predatory street taxis.
Relying on public Wi-Fi is a massive security risk, and local SIM cards often require navigating language barriers and complex registration processes. The smartest way to secure a stable connection the minute you land is by downloading a reliable digital data pack.

A Paraguay eSIM allows you to bypass the kiosks entirely and step out of the airport with a secure, fast connection ready to go.
