If a motorist was pulled over, the enforcers approach would be more professional like so they won't lose their image as a respected law enforcer. This section talks about how police officers use their 'tolerance levels' to decide if they should take action or not. What I mean by tolerance level is the officer's own laws. 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.
