What does 'traffic enforcement' involve?

Traffic enforcement primarily involves ensuring compliance with traffic laws and regulations. This encompasses a wide range of activities aimed at maintaining road safety, which includes monitoring vehicle speeds, checking that drivers follow traffic signals, using seat belts, and more. The goal is to uphold the law to prevent accidents and promote safe driving behaviors.

Addressing the other options, while conducting investigations on traffic violations is a component of traffic enforcement, it is a narrower aspect compared to the broader role of ensuring compliance. Training new officers in traffic regulations, though important for maintaining an informed police force, does not directly relate to the active enforcement of laws on the road. Issuing fines for parking violations is a specific task within traffic enforcement but does not encompass the entirety of what traffic enforcement involves, as it deals with a subcategory of the broader traffic law compliance issues.
