Speed limit road signs are a common sight in every country around the world. Its primary purpose is to control the speed of traffic and make roads safer for drivers, passengers and pedestrians alike. Markers often indicate a constant maximum speed although variable speed signs are also common. Variable speed signs can be obligatory and advisory in nature.
Mandatory signs are always placed in a red ring, indicating its importance and inalienable category. These procedures must be followed strictly if you want to stay within the law and drive safely. However, she can also be a nature consultant. These signs are installed as a temporary measure to warn motorists of an imminent danger for a specified period of time.
Variable speed road signs
As mentioned above, all mandatory marks are placed in a red ring. Any other mark is advisory in nature and it is up to you to interpret it the way you want it. Some vehicles also have an automated system with traffic lights to control traffic speed. Here too, a mandatory signal will be placed in a red loop while advisory marks will be indicated by flashing amber lights.
The purpose of a variable speed
The primary purpose is to allow motorists the freedom and flexibility to travel at an appropriate speed, depending on prevailing weather or road conditions. It is also an effective way to align the total traffic flow on a given lane to prevent flow outage in case of high traffic volume.
The speed of control also affects the environment, and mandatory and consulting signs can indeed make your environment a better place to live.
Variable speed for safer roads
Training rituals can transform even the best maintained methods into deadly traps for motorists. Rain, snow, snow, strong winds, dust storms, etc. not only reduce visibility, but also make roads slippery or unsafe.
The variable signals installed when entering the corridors and tunnels are an indication that the road ahead is not in the best conditions and you must reduce the speed for your safety. Mandatory Variable Marks (attached to a red ring) indicate that it is necessary to slow down while the advisory mark leaves the decision on you (in the event that the road is not severely affected but still needs careful driving).
Variable speed to improve traffic control
Mandatory signs and mandatory signs are also an effective way to better manage traffic. It is not always safe or possible to follow the top speed limit on all major or minor roads. Even on major highways, driving at full speed can lead to breakdowns or accidents that lead to traffic jams. A variable speed mark is used to reduce the intensity and duration of crowding and also to avoid accidents as possible.
Variable speed for a better environment
Speed control also goes a long way in mitigating harmful environmental impacts of traffic such as excessive noise and toxic smoke emissions. When people lead in a controlled manner, there is little reverence in trumpets. When cars start and stop frequently due to traffic, the polluted smoke will be reduced in the environment.
