Speed signs on highways and roads are a common occurrence in nations across the globe. Their basic use is to control and manage traffic speed and make the roads much safer for pedestrians, passengers and motorists alike.

Often, such signs mention a fixed maximum speed for the convenience of motorists although there are signs for variable speed too. Mandatory signs are always enclosed within a red ring which indicates their importance and obligatory nature.

Such signs should always be followed if you want to drive safely and stay within the laws of your area. However, advisory signages are common too. These are installed as a temporary measure for a specific period of time to inform traffic about a temporary danger or obstruction. Such advisory signs are removed once the danger or the obstruction is removed from the road.

Why have Signage for Variable Speed

Signage allows motorists the flexibility and freedom to drive at a speed they are comfortable with. Whether mandatory signs or advisory in nature, the signages allow you to control your speed depending on prevailing road condition, weather conditions and your own priorities. With a sign in place, you no longer have to follow a maximum/minimum speed limitation and can drive at your own pace.

Moreover, variable is also very effective in harmonizing the entire flow of traffic on carriageways so as to minimize the chances of flow breakdown in case of excessive traffic volume.

Controlling traffic speed is also essential for a safe and secured environment and reduces the risks of accidents and collision. Variable speed signs can actually make roads and neighbourhoods a much better place to live in.

Signs for Safe Carriageways

Even the best-kept roads and carriageways turn into potential death traps for drivers and pedestrians because of inclement weather. This is a common occurrence throughout the year as rain, snow, ice, dust storms etc can make roads dangerous, slippery and difficult to manoeuvre at a set speed.

Variable signs installed at appropriate intersections or entry of tunnels or carriageways are extremely effective as an indication that road is not in perfect condition and you may have to change your speed accordingly.

Signs for Superior Traffic Management

Mandatory signs and advisory signs also play a crucial part in better traffic control and management. It is not possible for you or others to drive at a fixed speed over long distances for hours across all roads and carriageways.

Even on wider roads, driving at high speed may lead to accidents and unnecessary bottlenecks. Variable speed signage is therefore used to control traffic congestion and duration and also reduce risks of collision as much as possible.

Signs for Healthier Environment

Driving at high speed also has several detrimental effects on public heath such as creating more noise pollution or emission of more poisonous fumes. However, when people follow variable speed and drive in a controlled way, there is less honking and less traffic congestion all around.
