In general, Serbia is a safe location to visit. In case you need assistance, the people are very courteous and friendly. (If you need assistance finding/getting to a location, it’s better to ask a younger individual, since they are more likely to know English.) Pickpockets should be avoided at all costs, especially in busy tourist areas and on public transit. Street robberies, murders, or assaults are very rare, especially in isolated or dark areas of a city/town. Drivers that are disrespectful to pedestrians or cyclists should be avoided at all costs. There is also considerable hostility against gays.
The emergency phone numbers are 192 for police, 193 for fire, and 194 for ambulance.
Following the Yugoslav conflicts of the 1990s, there have been reports of UXOs (unexploded ordnances) outside of major cities. When traveling outside of cities, keep an eye out for marks that may indicate a possible UXO zone and always adhere to well-trodden routes. If you come across a strange item that resembles a bomb/mortar/landmine, DO NOT TOUCH IT. Notify the closest police station right away. Although the majority of UXOs have been removed, it is extremely improbable that you will discover any of them, even in the least frequented areas of Serbia.
