Tehran is generally safe for both residents and tourists regarding violent crime, though its size and density require standard urban precautions.
* **Emergency Numbers:** Police: 110 | Ambulance: 115 | Fire: 125 * **Crime:** Violent crime against foreigners is rare. Petty crime, such as bag-snatching or pickpocketing, can occur in crowded areas like the Grand Bazaar or on the Metro during rush hour. * **Traffic:** The greatest physical hazard in Tehran is road traffic. Crossing the street can be intimidating; visitors are advised to move at a steady, predictable pace, allowing drivers to maneuver around them. * **Local Laws:** Visitors must adhere to national Islamic laws. This includes a strict ban on alcohol and pork, and mandatory dress codes (hijab/headscarves and loose-fitting clothing for women; long trousers for men) in all public spaces.
