September is National Child Passenger Safety (CPS) Month, which offers an opportunity for parents and guardians to make sure they are up to date on Nevada’s CPS law, as well as to conduct an annual check that their child is using the correct restraint for their age, height, and weight. In 2020, there were 656 deaths of child occupants between the ages of 0-12 years in motor vehicle crashes in the U.S. [1].

Appropriately selected and installed Child Restraint Systems (CRS) can reduce the risk of death by as much as 71% [2]. According to the National Highway Safety Association (NHTSA), many kids 8 to 12 years old still need to use a booster seat [2]. It is important to make sure they ride in a booster seat until they outgrow the size limits of their booster, or until they are big enough for an adult seat belt to fit them properly. Appropriate progression from one CRS to the next is based on the child’s age, weight, height, and product manufacturer limits to ensure restraint effectiveness in the event of a motor vehicle crash.
According to the Nevada Department of Motor Vehicles, 7 out of 10 child safety seats are installed improperly, which is why it is important to be up to date on manufacturer recalls and inspection (see page 3 for inspection site resources near you) [3]. This TREND in Focus analysis investigates the prevalence and demographics of Nevada drivers who were cited for CPS-related violations from 2018-2021 (N=2,265).



According to best practice guidelines, rear-facing car seats are used for children 2 years old, forward-facing seats are for children between 2-3 years old, and children ages 4-7 are typically restrained in booster seats [3]. Beginning 2022, Nevada’s car seat laws were revised requiring that children under 6 years old and under 57 inches tall be restrained in a child restraint system (CRS) that is appropriate for size and weight of the child. Drivers cited for failing to secure children in proper CRS will face fines or community service hours (NRS 484B.175). From 2018-2021 there were 1,425,762 traffic citations issued by law enforcement in Nevada. Of those, 2,265 (0.16%) were CPS-Related violations.


Drivers issued a CPS-related citation were on average (mean) 33.5 years of age (median 31, Interquartile Range 26-38.5 years) (Fig.1). Approximately one-quarter (25.0%) of all CPS-related citations were issued to drivers between 26-30 years old. Women were more frequently cited than men (53.4% vs. 46.6%). The race and ethnicity breakdown for CPS-related violation citations were: White (37.5%), Black (21.5%), Hispanic (11.0%), Asian (2.4%), and Indian (Native American) (1.4%), with 26.1% reported unknown. The majority of citations were issued in Clark County (N=1241, 55.4%) and Washoe (N=281, 12.5%). Of those citations, approximately 8 of every 10 drivers hold Nevada driver’s licenses and have vehicle registered in Nevada.

CPS-Related Violator Age

Citation Information

Citations issued were evenly distributed throughout the week with Friday (16.1%) being the day with the most frequent citations issued, and Tuesday and Saturday the lowest (13.4%). An even distribution is also observed across violation months with the highest prevalence in August (9.6%) and May (9.5%), and lowest in December (6.6%) and November (6.8%). Approximately 3 in 10 citations were cited between 12PM and 6PM (28.3%). Traffic volume at the time of violations was primarily light (47.1%) and moderate (45.8%). The road conditions reported for majority of the citations were dry and clear (96.8%). Of those who are cited, 6 out of every 100 (n=131) issued citations were associated with a crash.

Traffic Safety Research Staff Share Findings on Nevada Non-Adjudicated Citations and More!

By Kalen de la Garza, Merika Charupoom, & Emily Strickler, MPH

Association of Transportation Safety Information Professionals – Traffic Records Forum 2022

In August, our team attended the 2022 Traffic Records Forum held in Denver, Colorado. Our Research Assistant Emily Strickler presented research on Nevada non-adjudicated (issued citations that have not been finalized by a court) distracted driving citations. At this meeting, our Project Director, Laura Gryder, and Emily attended workshops focusing on the Bipartisan Infrastructure Law requiring revising the definition of non-motorists to include e-bikes and electric scooters, and roundtables focused on best practices for data integration across different traffic records types. Our team was also able to attend presentations by researchers in Connecticut who are focusing on assessing equity among traffic stops in their states. Other presenters shared their work with citation data in their state, making this conference a great opportunity to learn new information and make connections with other traffic records professionals.

Nevada Public Health Association – Annual Conference 2022

In September, several of our research team members attended the 2022 Annual Conference for the Nevada Public Health Association (NPHA) in Las Vegas. Emily Carter, a first year medical student and one of our former student researchers, shared a presentation on Non-Adjudicated Distracted Driving Citations with Research Assistant Emily Strickler. Merika Charupoom, Student Researcher, shared hospital outcomes by helmet status among pediatric trauma patients injured while riding Off-Highway Vehicles (OHV) and All-Terrain Vehicles (ATV). This research utilized a subset of data from our longitudinal linked crash-trauma database. Finally, Emily Strickler presented findings from a descriptive analysis of Non-Adjudicated Traffic Control Device Violations in Nevada from 2018-2021. Injury prevention is an important aspect of public health, and our team was honored to share our research in this forum.

Teaching the Traffic Safety Professionals of Tomorrow: National Summer Transportation Institute 2022

Our traffic safety research team members once again hosted a Calculating Statistics of Traffic Safety class during the National Summer Transportation Institute (NSTI) held by the UNLV College of Engineering in July. NSTI is a free two-week summer camp for high school students interested in STEM (Science, Technology, Engineering and Mathematics) disciplines, especially related to the transportation industry. The purpose of the program is to broaden student interest in transportation science. This summer camp has been a collaboration between UNLV’s Multicultural Program for STEM and Health Sciences and the Road Equity Alliance Project (REAP) since 2014. After a two-year hiatus for in-person learning, students were able to complete their NSTI experience together on campus this year.

Our team members, Ana Reyes and Merika Charupoom, taught the students about descriptive statistics and best practices for visualizing data. As a hands on activity, students were able to work with real traffic safety data, specifically 2019 Clark County pedestrian self-reported citation data from over 800 individuals. Each student was able to identify variables of interest, form a hypothesis, manipulate the data to examine relationships, and present their results to the class. Students utilized these data to hypothesize that pedestrians face a wide variety of risk factors that can make traveling dangerous for them.
