This research aimed to understand the relationship between law enforcers performance and law enforcement operations effectiveness. It focused on the moderating role of Land Transportation Office (LTO) Personnel Behavior. Quantitative research design was used thru descriptive-correlation analysis. One hundred twenty respondents from three types of transacting public at the Land Transportation Office (i.e., motor vehicle registrants, drivers license applicants, and apprehended drivers) were chosen through random stratified sampling and requested to participate in the study. Data were collected through a structured survey questionnaire and were interpreted. Analysis of data revealed that the transacting public gave a favorable high regard to the performance of law enforcers in terms of conducting road safety awareness programs, traffic enforcement and apprehension, traffic management, and roadside and bus terminal inspection. In terms of the effectiveness of law enforcement operations, results showed a highly adequate perception, leading to a significant relationship between the performance of law enforcers and law enforcement operations. The results also revealed that the moderating role of LTO personnel behavior has been highly accepted by the public and was highly significant. However, data showed that it weakened the relationship between the performance of law enforcers and law enforcement operations. Consequently, there is a necessity to improve personnel behavior since there are issues of bribery and extortion even though the transacting clients highly accepted the LTO personnel behavior has a high accepted by the transacting clients.
