Tallinn, much like the rest of Estonia, boasts a low crime rate. The main concern here is pickpocketing, especially in crowded bars or amidst large crowds. It's important to note that consuming alcohol in public places and on public transportation can lead to legal issues for tourists.
In Tallinn, the most significant concern is the presence of winter ice. When driving, it's crucial to prepare your vehicle for winter conditions, including the use of winter tires, which is a legal requirement. Typically, the period of "winter driving" lasts from December 1 to March 1, although Estonian authorities can adjust it based on current weather conditions.
