The purpose of this paper is to analyze trends in fatal law enforcement officer (LEO) traffic collisions and describes prior research approaches and industry responses. It reviews the issue from historical and contemporary perspectives and details its problems for public policy.

Descriptive statistics are applied to data primarily covering the period 1995 to 2010 contained in the Federal Bureau of Investigation Crime in the USA and LEO Killed and Assaulted reports and the National Highway Transportation Safety Administration Fatality Analysis Reporting System database. Trends are established and comparisons are offered between groups.

Traffic collisions are the leading cause of death for LEOs. Traffic fatalities in the general public have steadily decreased in past decades. This has not been the trend among LEOs. This issue has been studied from several disciplinary perspectives in the social, cognitive, biological, engineering, and natural sciences. While the law enforcement industry has documented the trend, concerted efforts to mitigate the issue have been limited until recently.

Law enforcement practitioners and policymakers should take note of research findings and pursue training, policy, and practice changes to limit LEO traffic fatalities and effect an improvement trend consistent with the national reduction in highway deaths.

This paper brings together previously uncoupled data sources and prior research to identify problematic trends and contextualize LEO traffic fatalities as a subset of all traffic fatalities. It provides law enforcement policymakers a stark and revealing assessment of the most dangerous aspect of their field.

The purpose of this paper is to investigate variability in law enforcement officer (LEO) traffic fatality rates among states in order to identify policy-relevant areas of opportunity to reduce deaths.

Differences in state highway spending, regulatory policy, law enforcement training, LEO and general public traffic fatalities, and other state-level variables are explored through cross-sectional regression analysis and qualitative content analysis. Data were used from the Federal Bureau of Investigation Crime in the USA and LEOs Killed and Assaulted reports, and the National Highway Transportation Safety Administration Fatality Analysis Reporting System, among other sources.

There are a number of significant state-level variables and trends that contribute to differences in LEO traffic fatality rates. Maximum highway speed limits and general population traffic fatalities are found to be statistically significant predictors. Thematic factors relating to LEO exceptionalism, agency sovereignty, training, and external control loci, emerged through qualitative analysis.

Limitations included differences in definition, consistency, and reporting among data sources. Qualitative analysis of some variables were limited and future research should pursue more robust and repeated/longitudinal measures.

Policymakers have an opportunity to review significant factors contributing to higher/lower collision involvement rates and make changes to police practices to reduce collision involvement and improve safety for LEOs.

No prior study has offered a national, cross-case analysis of LEO traffic fatalities by state. This paper offers law enforcement policymakers empirical examples of successful LEO traffic safety policies.

Concerns about the risk of traffic collision injury to both police officers and bystanders are increasing as the use of in-vehicle technologies becoming widespread among agencies. This study used national and California data to characterize traffic collisions in which a police vehicle was involved. The paper aims to discuss these issues.

The authors used a California traffic collision database to retrospectively identify collisions that involved police vehicles for years 2007-2010. The authors summarized collision characteristics with descriptive methods and used log-binomial regression to estimate associations between personal and collision characteristics with officer culpability.

The authors identified 5,233 traffic collisions in California. In total, 10 percent of law enforcement vehicles were motorcycles. In all, 9 percent of cruisers struck a pedestrian or bicyclist, compared with only 2 percent of motorcycles. Compared with officers aged 50 or older, officers in younger age categories were progressively much more likely to have been culpable. Motorcycle officers were 33 percent less likely to be culpable for their collision involvements. Approximately 100 fatal collisions involving a law enforcement vehicle occur each year in the USA.

The findings from this study indicate that approximately 1,300 injury-producing traffic collisions occur each year in California that involve a law enforcement vehicle. The authors found that younger age, female sex, cruiser operation, traveling unbelted, and single-vehicle collision involvement were positively associated with officer culpability. Officer race and community population were not significantly associated with culpability. The occurrence of fatal collisions in the USA was stable over a 12-year period.

This paper seeks to analyze how institutional arrangements and discourses shape law enforcement professionalization efforts, to identify opportunities and potential problems associated with professionalization, and to propose research to address practitioner interests in education and training and public interests in accountability and service equity.

The paper explores discourses surrounding law enforcement professionalization efforts to identify implementation barriers and potential consequences. It reviews earlier literatures and analyzes occupational standards data, utilizing a communicative perspective to investigate professionalization problems that have often been approached from political or economic perspectives.

Although law enforcement is often urged to professionalize, educational standards for officers remain low. There is no clear nexus between college curriculum and law enforcement as a profession. This paper shows that competing discourses about professionalization in general and law enforcement in particular undermine efforts to establish professional status and increased standards for law enforcement.

Future research should include greater cross‐sectional data analysis. Investigation of law enforcement standards or professionalization should account for social discourses that contribute to norms and expectations.

Law enforcement agencies and criminal justice programs have opportunities to better coordinate practice and scholarship. Failure to attend to institutional relationships and the role of communication in shaping professional standards will hamper advances in either field.

The paper shows that professional norms shape law enforcement accountability to the public in critical and sometimes unintended ways.

Previous authors have not considered social discourse impacts on law enforcement standards and professionalization, nor their relationship to higher education. By introducing these variables, barriers and alternative approaches are revealed.

Little is known regarding the impact of organizational policies and practices on police officers’ driving behaviors. To address an important gap in the empirical literature, this study examined how perceived likelihood of discipline for violations of agency driving policies impacted officer-involved vehicle collisions.

Surveys were distributed to patrol officers and their supervisors in eight California law enforcement agencies. The surveys elicited information regarding the perceived likelihood of discipline for violations of agency driving policies regarding cell phone use, text messaging, seatbelt use, speeding, and vehicle operations during emergency and pursuit situations.

The findings demonstrated a significant impact of perceived likelihood of enforcement for some but not all agency driving policies on officer-involved vehicle collisions.

This study was limited to self-reported data from patrol officers and their supervisors in eight California agencies.

Findings suggest that agencies may reduce officer injuries and other costs by increasing supervision and enforcement of agency driving policies.

This study contributes to the extant body of literature on officer-involved vehicle collisions by considering the impact of agency policy and supervision on officer behavior.

The purpose of this paper is to examine the situational and individual officer characteristics of officer-involved vehicle collisions that result in fatality, injury, and non-injury outcomes.

Data on 35,840 vehicle collisions involving law enforcement officers in California occurring between January 2000 and December 2009 are examined. A descriptive analysis of collision characteristics is presented.

There were 39 officers killed by collisions over this study period and 7,684 officers who received some type injury. Incidents involving officers on motorcycles represented 39 percent of officer fatalities and 39 percent of severe injuries. In the case of fatalities, 33 percent of officers were reported as wearing seatbelts, 38 percent were not wearing a seatbelt, and seatbelt use was not stated in 29 percent of car fatalities.

The findings only represent one state and the analysis is based on an estimated 86 percent of collisions that occurred during the study period due to missing data. Nonetheless, the results are based on a robust sample and address key limitations in the existing literature.

During the study period in California the estimated financial impact of collisions reached into the hundreds of millions of dollars when considering related fatality, injury, and vehicle damage costs combined. These impacts highlight the need for the law enforcement community to give greater attention to this issue.

At the time of this writing there was no published independent research that compares the situational and officer characteristics across fatality, injury, and non-injury outcomes in these events. The findings reported here will help inform emerging interest in this issue within the law enforcement, academic, and policy-making communities.

Vehicle crashes and being struck by vehicles are the leading causes of death among police. The purpose of this paper is to identify risk factors for injury in police officer vehicle crashes in order to help determine the most effective approaches to improve officer vehicle safety.

The study entailed a cross-sectional survey of officer drivers involved in vehicle crashes from 16 local, county, and state law enforcement agencies across the USA over one year. The relative risk of injury for officers in crashes with a given characteristic relative comparison crashes without that characteristic was computed to determine which characteristics are more likely to be associated with injuries.

The survey yielded 854 crashes, 90 of which involved injuries to the officer driver. Crash characteristics associated with a statistically significant increase in the risk of injury include multiple vehicle collisions, collision direction, officer vehicle type, officer vehicle being stopped, driving under emergency conditions, conducting traffic control or assisting motorists, not wearing a seat belt, and others. Most findings hold for all crashes and when minor crashes are excluded from the analysis.

This study presents the first quantitative estimates of the risk factors for injury to law enforcement officers in vehicle crashes. Our findings indicate that seat belt use remains a critical safety intervention; driving under emergency conditions is high risk, though the reasons for this are unclear; better practices are needed to protect officers in stationary vehicles; agencies should carefully weigh the benefit of motorcycles against the vastly increased risk of injury they present; and that mobile data terminals are both a major distraction hazard and important source of injuries in crashes.

Fatigue associated with shift work is a well-established and pervasive problem in policing that affects officer performance, safety, and health. It is critical to understand the extent to which fatigue degrades officer driving performance. Drowsy driving among post-shift workers is a well-established risk factor yet no data are available about officer injuries and deaths due to drowsy driving. The purpose of this paper is to assess the impact of fatigue associated with work shift and prior sleep on officers’ non-operational driving using laboratory experiments to assess post-shift drowsy driving risks and the ability of a well-validated vigilance and reaction-time task to assess these risks.

Experienced police patrol officer volunteers (n=78) from all four shifts of a medium-sized city’s police department were tested using a within- and between-subjects design to assess the impact of fatigue on individual officers, as well as the impact of different work shifts, on post-shift driving performance. Controlled laboratory experiments were conducted during which participants drove high-fidelity driving training simulators on two occasions: immediately following five consecutive 10:40-hour patrol shifts (fatigued condition) and again 72 hours after completing the last shift in a work cycle (rested condition).

Generalized linear mixed-model analyses of driving performance showed that officers working night shifts had significantly greater lane deviation during post-shift, non-operational driving than those working day shifts (F=4.40, df=1, 150, p=0.038). The same method also showed that easy to measure psychomotor vigilance test scores for reaction time predicted both lane deviation (F=31.48, df=1, 151, p < 0.001) and collisions (F=14.10, df=1, 151, p < 0.001) during the simulated drives.

Simulated driving tasks done by participants were generally less challenging than patrol or off-duty driving and likely underestimate the impact of fatigue on police driving post-shift or during extended shifts.

This is the first experimental research to assess the impact of shiftwork, fatigue, and extended shifts on police post-shift drowsy driving, a known risk factor for shift workers in general.

The purpose of this paper is to investigate the role that agency culture, training, and supervision play in the rates of on-the-job seatbelt use among peace officers, as well as other officer safety-related driving concerns such as cell phone use, Mobile Data Terminal use, and other sources of distraction.

Based on semi-structured interviews with California peace officers.

This study found an array of agency culture issues related to on-duty collisions, including distraction, failure to follow policy or procedure, fatigue, self-selection processes among officers and agencies, supervision and field training processes, morale issues, and family/lifestyle issues.

To explain these agency culture findings, this paper introduces the concept of the “banality of risk” to understand why many officers choose not to use risk-attenuating equipment. The findings are suggestive of a set of best practices that agencies could consider regarding in-vehicle officer safety.

Motor-vehicle-related events (MVEs) are the leading cause of on-duty death for law enforcement officers, yet little is known about how officers view this significant job hazard. The purpose of this paper is to explore officers’ motor-vehicle risk perception and examine how prior on-duty MVEs and the death or injury of a fellow officer influences this perception.

A state-wide random sample of 136 law enforcement agencies was drawn using publically accessible databases, stratified on type and size of agency. In total, 60 agencies agreed to participate and a cross-sectional questionnaire was distributed to 1,466 officers. Using six-point Likert scales, composite scores for motor-vehicle and intentional violence risk perception were derived. A linear regression multivariable model was used to examine factors affecting motor-vehicle risk perception.

Motor-vehicle risk perception scores were significantly higher than intentional violence scores. A prior on-duty motor-vehicle crash, prior roadside incident, or knowledge of fellow officer’s injury or death from a MVE significantly increased motor-vehicle risk perception scores. After controlling for potential confounders though, only prior on-duty crashes and roadside incidents impacted motor-vehicle risk perception.

The study comprised primarily small, rural agencies and generalizability may be limited. Also, although the data were collected anonymously, reporting and response biases may affect these findings.

This study involved a large and diverse cohort of officers and explored motor-vehicle risk perception. A better understanding of officers’ risk perceptions will assist in the development and implementation of occupational injury prevention programs, training, and policy.
