Challenges of enforcing cellphone use while driving laws among police in the USA: a cross-sectional analysis

OBJECTIVES: Research suggests that cellphone use while driving laws may be difficult for police to enforce in the USA, but this is unknown. A national survey of police officers was conducted to determine whether barriers to enforcing these laws exist, what aspects of laws make them easier to enforce and ways to discourage the behaviour among drivers. DESIGN: Cross-sectional survey. SETTING: USA. PARTICIPANTS: Individuals >18 years of age employed as a law enforcement officer from all 50 states were recruited via convenience sampling through multiple modalities from November 2019 to April 2020. Officers (N=353) from 31 states participated. PRIMARY AND SECONDARY OUTCOME MEASURES: Descriptive statistics and multi-level logistic regression analyses were run to assess the responses. RESULTS: The most common barriers to enforcing texting bans (ie, the most prevalent law) were drivers concealing their phone use (78%) and the officer not being able to determine what the driver was doing on their phone (65%). If a universal hand-held cellphone ban was in effect in their state, officers were 77% less likely (adjusted OR=0.23; 95% CI 0.08 to 0.70) to report that a texting ban was difficult to adjudicate. The majority of officers (86%) agreed that having one general law that prohibits any type of hand-held cellphone use would aid with enforcement, and that laws must be a primary offence (87%), and be applicable to all licensed drivers (91%). Most officers felt that driver education is needed. CONCLUSIONS: While numerous barriers to enforcement were identified, opportunities exist to improve current legislation to aid enforcement efforts and to prevent the behaviour among drivers.
