Greece's revised traffic code (September 2025) introduced significantly higher fines that apply to all drivers, including tourists with rental cars. Phone use while driving: €350 (doubled from previous amount). Speeding: up to €700 depending on how far over the limit. Running a red light: €700. Not wearing a seatbelt: €350. Drunk driving: €350-€2,000 depending on blood alcohol level, plus license suspension and potential vehicle impoundment. Parking violations: €40-€150. Greek traffic police have increased enforcement with speed cameras and random checkpoints. Rental car companies pass fines directly to the renter's credit card, often with an additional administration fee.

All roads in Thessaloniki and throughout Greece — speed cameras on major highways, police checkpoints in the city, and parking enforcement in the city center.

Greek law prohibits removing natural materials from beaches — seashells, sand, pebbles, driftwood, and marine specimens. Fines range from €500 to €1,000 depending on the quantity and type of material taken. Customs officials at airports and ports are trained to check for these items and can inspect your luggage. This law protects Greece's coastal ecosystems and applies to all beaches nationwide, not just protected areas. Even a small collection of shells in your suitcase can result in confiscation and a fine. The law is actively enforced, particularly during peak tourist season when departing flights are monitored.

Greece bans high heels and hard-soled shoes at archaeological sites to protect ancient stone surfaces that are irreplaceable. Fines can reach €900. Thessaloniki has several major archaeological sites where this applies: the Rotunda (a 4th-century Roman structure), the Roman Forum, the Arch of Galerius, the White Tower, and the Archaeological Museum of Thessaloniki. The rule exists because pointed heels concentrate body weight onto tiny contact points, causing measurable damage to marble, limestone, and ancient paving stones. Guards at site entrances may refuse entry or provide shoe covers. This rule applies to all visitors regardless of gender.

Greece enforces afternoon quiet hours (mesimeri) — a cultural tradition that is also backed by law. Between approximately 3 PM and 5 PM and again from 11 PM to 7 AM, excessive noise in residential areas is prohibited. Fines range from €100 to €500. This is particularly relevant in Thessaloniki where tourist areas overlap heavily with residential neighborhoods — the Upper Town (Ano Poli), areas around Aristotle University, and residential streets near the nightlife districts of Ladadika and Valaoritou. Tourist group noise, loud phone conversations in the street, and dragging wheeled suitcases over cobblestones during quiet hours all generate complaints from residents.

Wild camping is illegal throughout Greece, including on beaches, in parks, forests, and other public areas. Fines are approximately €300, and police actively enforce this during summer months when tourists attempt to camp on popular beaches. In the Thessaloniki region, this particularly applies to the beaches of Peraia, Agia Triada, and Epanomi, as well as the more remote beaches of the Halkidiki peninsula where backpackers sometimes attempt to camp. Sleeping in your car or campervan outside designated areas is also considered wild camping and subject to the same fines. Greece has affordable campsite options — use them.

Greece banned indoor smoking in all public spaces in 2010, but enforcement was notoriously lax for years — Greeks had one of Europe's highest smoking rates and many bars and restaurants simply ignored the law. Since 2019, enforcement has improved dramatically with dedicated inspection teams and higher fines. Fines for smoking indoors now range from €50 to €200 for individuals, with venue owners facing penalties of €500-€10,000 for allowing smoking. Outdoor restrictions are expanding — smoking is now prohibited near hospital entrances, school grounds, and some public building areas. The cultural shift is real but gradual — you may still encounter occasional indoor smoking in smaller, local establishments.

Greece is aggressively expanding Airbnb and short-term rental restrictions beyond Athens to major cities including Thessaloniki. Since October 2025, all short-term rentals must meet stricter safety standards including fire safety equipment, emergency exits, and structural integrity certificates. Properties must hold a valid AMA (Arithmos Mitroou Akinitou) registration number displayed on all listings. Unregistered properties face fines of up to €20,000 for operators. As a guest, you won't be fined, but staying in an unregistered property risks cancellation mid-stay if authorities discover the violation. The crackdown reflects growing concerns about housing affordability for locals as tourist rentals reduce long-term housing supply.

Greece has strict drug laws. All recreational drugs including cannabis are illegal. Possession of even small amounts for personal use can lead to criminal prosecution — Greek law distinguishes between 'use' and 'supply' but the threshold is subjective and determined by courts. First-time offenders caught with small amounts for personal use may receive a suspended sentence or referral to a drug program, but this is not guaranteed. Supply or trafficking carries severe prison sentences of 5-20 years. Medical cannabis is legal only with a Greek prescription. Greek police conduct operations in nightlife areas, festivals, and border crossings.

Greek law mandates that at least 70% of beach space (85% in environmentally protected areas) must remain free and accessible to the public. Beach businesses cannot occupy more than 30% of the beach with commercial sunbeds and umbrellas. This means you always have the right to lay your own towel on the free section of any beach — even if sunbed operators try to suggest otherwise. Some beach businesses have been known to aggressively claim entire beaches as commercial space, placing sunbeds across areas they're not licensed for. If challenged, stand your ground — the law is on your side.

Greece charges a Climate Resilience Fee (TAKK — Telos Anthektikotitas stin Klimatiki Krisi) on all tourist accommodation, applied per room per night year-round. Rates vary by property star rating: €15/night for 5-star hotels, €10 for 4-star, €3 for 3-star, €1.50 for 2-star, €0.50 for 1-star. Short-term rentals (Airbnb, etc.) are charged €1.50/night. The fee was introduced in 2018 and expanded in subsequent years. Revenue funds climate adaptation measures and tourism infrastructure. The fee is added to your accommodation bill and cannot be avoided — it's a legal requirement.

Greek law requires everyone over the age of 14 to carry valid identification at all times. Police can request ID during routine checks, which occur in nightlife areas, at transport hubs, and during traffic stops. For tourists, a valid passport or national ID card (for EU/EEA citizens) is required. While you're unlikely to face a formal fine for not having ID on the spot, police may detain you until your identity is verified — which can mean a trip to the police station and a significant disruption to your day. Photocopies of your passport are generally accepted for casual police checks but may not suffice for official situations.

All of Greece — police checks are common in Thessaloniki nightlife areas (Ladadika, Valaoritou), at the port, at the airport, and during traffic stops.

Greece charges cruise passengers a disembarkation fee that varies by destination tier and season. Thessaloniki falls in the standard tier with fees of: €5 per passenger in peak season (June-September), €4 in shoulder season (April-May, October), and €1 in winter (November-March). This is significantly cheaper than premium Greek island ports — Santorini and Mykonos charge €20 per passenger in peak season. The fee is typically included in your cruise line charges and doesn't require separate payment. Thessaloniki's cruise port is conveniently located near the city center, making it easy to explore on foot.

Pickpocketing occurs in Thessaloniki's busiest areas, though the city is generally safer than Athens for this type of crime. Hotspots include Aristotelous Square (the city's main square, always crowded), the waterfront promenade, crowded buses (especially lines to/from the airport and university), and the Modiano and Kapani markets. Techniques include distraction (someone asking for directions or showing you a clipboard petition while an accomplice takes your wallet), crowding on buses, and bag-snatching at outdoor cafe tables. The risk increases during peak tourist season (June-September) and during major events and festivals.
