Imagine there were no signs?

If there were no signs or signals indicating what we should do and when we should do it, our traffic system would be a mess. Traffic control devices ensure the orderly movement of traffic. Drivers must obey traffic signals unless a law enforcement officer is otherwise directing traffic.

Traffic signs help regulate the flow of traffic by regulating, warning and informing. Regulatory signs manage the flow of traffic by telling road users what to do. Drivers must obey them, as they have been put in place for your safety and so that the flow of traffic can be as efficient as possible. Warning signs tell drivers of road conditions ahead and inform them of situations to watch out for. These signs must be obeyed for safety reasons, and ignoring them is a violation of traffic laws. Guide signs tell drivers which road they are traveling and how to get where they are going. They also provide information to make trips more interesting. These signs help make the flow of traffic more efficient by designating lanes to not only direct traffic but also direct the flow of traffic and avoid congestion as much as possible. Pavement markings manage the flow of traffic by directing drivers and regulating lane use and congestion. Traffic controls in construction zones manage the flow of traffic ensuring the safety not only of drivers in these areas, but also road maintenance workers. These devices alert drivers to unusual and possibly dangerous conditions. Construction workers stop, slow down and direct traffic safely and for the purpose of preventing accidents.
Laws change every year regarding traffic flow management. These laws are changed due to new concepts and statistics that are constantly being introduced. As new paths are created, we are provided with new scenarios that need to be addressed as they arise. In addition, we are constantly "tweaking" the traffic system to make the roads safer for everyone, especially as the volume of traffic increases almost daily.


Law enforcement officers are constantly challenged to stay current on current laws, and to know what has changed and what has been implemented. The main duty of a traffic officer is to ensure that all drivers using the road are obeying traffic control devices and other traffic laws. By removing drivers who do not obey these rules, they are helping to provide a safer flow of traffic for all drivers. The system only works when all drivers act in accordance with what they are required to do. Most accidents occur when one or more drivers do not obey traffic control devices, or when they break the law.
