For agencies who employ full time traffic enforcement officers or wish to, TERs would be limited to this function of enforcement and would not respond or be dispatched to general calls for service. TERs may also receive specialized training in accident investigations, which can be a tremendous time drain on full time officers.
Training: Due to the high risk involved while conducting traffic stops, this specialized level of reserves would most likely receive the highest level of training, closest to that of regular reserves, and should receive a significant amount of FTO time with a full time officer to insure they can safely conduct traffic stops.
The above examples are just some of the common duties officers perform which take away from their primary function of responding to calls for service and catching the bad guys. By thinking unconventionally and working with your reserve standards committees, the potential to keep more officers on the street to help combat the nation's rise in crime and offsetting any Homeland Security duties is tremendous. In the end, not only will your full time officers enjoy spending more time on the street doing what they do best, your specialized reserve officers will also benefit from becoming more proficient at the task they've chosen to do.
