Final answer:
Actions such as exceeding the speed limit and failing to obey traffic controls are traffic violations, which are illegal and unsafe driving behaviors that can lead to accidents and increased traffic congestion.
Step-by-step explanation:
Exceeding the speed limit, following too closely, driving slow in the fast lane, and failing to obey traffic controls are examples of traffic violations. These actions are contrary to the rules of the road, which are designed to ensure the safety and efficiency of road travel. Traffic signals and speed limits are assigned to control traffic flow and minimize accidents. For instance, when many vehicles speed through an intersection with disregard to the posted speed limit, a traffic signal can be installed to enforce a slowdown, improving safety for both motorists and pedestrians. Traffic violations not only increase the risk of accidents but also contribute to increased traffic congestion, which has negative environmental impacts due to higher emissions from idling vehicles.
