The speed limit sign is a crucial element of road signage, designed to inform drivers of the maximum speed allowed on a specific section of the road. These signs, often circular with a red border, display a number indicating the speed limit in kilometers per hour (km/h). The red color and white circle with the black number are internationally standardized elements indicating a speed limit. These signs play an essential role in road safety by guiding drivers and helping to maintain responsible and safe driving on the roads. Speed limits are generally determined based on the characteristics of the road, traffic density, and other considerations aimed at ensuring the safety of road users.
