Mandatory road signs are regulatory traffic control devices designed to inform road users of compulsory actions that must be followed to ensure safe and orderly movement on roads and highways. These signs are installed in accordance with prescribed traffic and road safety standards and are legally enforceable, requiring strict compliance by drivers and pedestrians. Mandatory road signs include instructions such as speed limits, compulsory turns, lane usage, pedestrian paths, and vehicle restrictions. They are manufactured using high-quality materials such as aluminum sheets with high-intensity retro-reflective films to ensure maximum visibility during day and night conditions. Engineered to withstand varying weather conditions, heavy traffic environments, and prolonged outdoor exposure, mandatory road signs play a crucial role in traffic regulation, accident prevention, and systematic traffic management while supporting compliance with road safety regulations and statutory requirements.
