When should a traffic violation warning be used?

A traffic violation warning should be used in every situation, and not just for repeat offenders or minor violations. A warning can help educate and remind drivers to follow the rules of the road, promoting overall safety and compliance. While strict compliance is important, using a warning system can also help prevent more serious violations and accidents from occurring. This option is the most comprehensive and effective approach. Options A, C, and D may have some merit in certain situations, but they do not address the overall goal of promoting safe and responsible driving behavior. It is important to use discretion when giving warnings, but they should not be reserved for only certain types of violations or individuals.
