Mandatory signs are an essential part of traffic rules and play a crucial role in maintaining road safety. These signs, also called traffic signs, provide specific instructions to road users and help them to behave correctly in different traffic situations. In this text we will discuss the different types of command signs and explain their meaning. One of the most common mandatory signs is the stop sign. This sign, which usually has a red color and a white border, indicates that drivers are required to come to a complete stop at the stop line or before the intersection. Ignoring this mandatory sign can lead to serious accidents and can be punished with a fine. Another important sign is the entry ban. This sign, which usually has a red circle with a white background and a black image of a prohibited action, indicates that a certain type of vehicle is not allowed on the road in question. This may, for example, apply to trucks, cyclists or moped riders. Ignoring this mandatory sign can lead to fines and in some cases even towing the vehicle. In addition, there are mandatory signs that indicate that a certain speed limit must be observed. These signs, which usually have a white circle with a red border and a black image of a number, indicate the maximum permitted speed on the road in question. It is important to respect these speed limits because speeding can lead to dangerous situations and may result in a fine. Another common mandatory sign is one-way traffic. This sign, which usually has a blue background with a white arrow indicating the direction of travel, indicates that traffic is only allowed in one direction on the road in question. Ignoring this mandatory sign can lead to dangerous situations and can be punished with a fine. Finally, there are mandatory signs that indicate that certain actions are prohibited, such as the ban on parking or the ban on using mobile phones while driving. These signs, which usually show a red circle with a black image, indicate that the action in question is not permitted at the indicated location. Ignoring these mandatory signs can lead to fines and in some cases even to the vehicle being towed away. In short, mandatory signs are vital for road safety and play a crucial role in enforcing traffic rules. It is essential for road users to understand and respect these signs to avoid accidents and fines. By paying attention to mandatory signs, we can all contribute to a safer and more orderly traffic environment.
