Not many people know why in the world people need portable traffic signs and it is understandable why those people do not understand because they never involve in a business where you have to disturb the traffic in order to get the job done. For example, as the 3rd company who provides repair service, dealing with leaking or bursting gas and water pipes means you need to temporarily disturb the traffic flow because the main pipes are located on the main streets. How do you properly warn the traffic users that their commute is about to be disturbed?
There are rules on how you properly disturbed the traffic flow and besides informing the local authorities, you also have to put a sign that you are currently working. The only way for you to announce that there is a job going on is by putting on portable traffic signals so anyone who passes through the traffic should aware and at least slows down their vehicle. The aforementioned traffic signals are not only announcing that the traffic flow is temporarily disturbed, but also to let traffic users know what type of job that makes their traffic disturbed. Some traffic signals are also used to divert the traffic flow to avoid massive traffic jam.
It is not that expensive to have the traffic signals especially when you have to work and temporarily disturb the traffic flow. The traffic signals are also important to lower down the risk of car accident due to drivers who are out of focus. If buying the portable traffic signs are considered as burden to your current financial condition, perhaps you can consider to buy the secondhand traffic signs or even rent the traffic signs although it would be considered as investment if you have your very own traffic signs as you can bring them wherever and whenever you need them.
