If drivers goes beyond an officer's tolerance level than the officer will take action. It is the same with time and the reason to issue a ticket. Officers also believe that such actions have a certain degree to it. I.e. rolling stops, yellow lights, and the type of car it is. Police officers need to live with themselves without feeling guilty.
Officers base their action of what they see and feel towards the violation.
This section describes the way police officers approach truckers and motorists. When a police officer approaches a trucker, they engage in a friendly conversation to lighten the mood of the situation or to establish a sense of businesslike manner. Police officers usually pull over truckers for investigation to see their rig, tires, lights, what they are carrying, what's in the cab and to check their log books. Whenever a police officer sees anything suspicious they tighten the inspection. Motorists were treated differently by police officers because of the respect officers need from the public.
