Summary

This study evaluates the effectiveness of New Jersey’s ban on hand-held cell phone use and texting while driving, which became a primary offense on March 1, 2008. The research was motivated by the persistence of distracted driving despite legislative efforts and the general belief that crash data attributable to phone use is under-reported due to driver non-admission and enforcement limitations. The primary objectives were to determine if the legislation reduced crashes, injuries, and deaths; to assess changes in law enforcement citation rates; and to gauge driver attitudes and compliance levels through a survey. The methodology involved a comprehensive review of crash and citation data from the New Jersey Motor Vehicle Commission, comparing pre-ban and post-ban periods. The researchers analyzed specific metrics for hand-held versus hands-free device usage, including crash counts, injuries, and fatalities. Additionally, the study examined citation data to evaluate enforcement intensity. To complement the quantitative analysis, a survey was conducted to measure driver knowledge of the law, self-reported compliance, and opinions on enforcement difficulties. The study also reviewed legislative history and compared New Jersey’s approach with other states’ laws and enforcement outcomes. The findings revealed that actual crashes involving hand-held cell phones increased after the ban was implemented, contrary to the goal of reduction. However, the number of citations issued for cell phone violations also increased, indicating heightened enforcement activity. Survey results indicated that while drivers were knowledgeable about New Jersey’s law, many admitted to violating it. Respondents supported stronger enforcement but acknowledged the practical difficulties police face in citing offenders. The data suggested that the legislation alone did not deter behavior, and that crash reporting may remain inconsistent. The study concludes that New Jersey’s cell phone ban has not effectively reduced crash rates associated with hand-held device use, despite increased citations. The authors recommend revising New Jersey’s crash reporting forms to better capture distraction-related incidents, advocating for consistent national legislation to standardize enforcement, and evaluating programs from other states. The research highlights the challenge of enforcing distracted driving laws and suggests that legislation must be paired with robust enforcement and public education to influence driver behavior. The findings contribute to the broader understanding that bans without sustained, visible enforcement may fail to alter long-term driving habits.

Key finding
