Highly publicized enforcement/education program designed to target the “aggressive driver” and promote courtesy.

Promoting an awareness of the aggressive driver behavior and ways to avoid inciting other drivers will reduce incidents of “road rage” since road rage itself is the culmination of an increasing continuum of minor discourtesies that evolve and escalate into road rage incidents.

For this agency, our current technique of monthly “road rage” days is most effective.

It gets us out there in force countywide, which is a great visible deterrent. The goal is that on “road rage” days, a motorist won’t be able to drive anywhere in Jefferson County without seeing a law enforcement officer engaged in traffic enforcement. Also this method does not cost us anything; we have a traffic enforcement team within our agency. On “road rage” days, they do what they normally do.

Aggressive “Pro-Active” traffic enforcement. Provide the right equipment of this unit will produce results.

This type of approach will produce a high visibility of police enforcement wherever it is implemented, with only 5 officers on my current team, we have a 100% increase in our traffic citations. The citizens of West Valley know we’re out there because they see us enforcing the traffic laws.
