This countermeasure involves States including cell phone restrictions in their GDL laws. These bans cover all cell phone use, not just handheld phones. In some States, the cell phone restrictions cover teenagers holding a learner’s permit and intermediate license; in other States, the restrictions cover all drivers under a certain age, such as 18 or 19 (GHSA, 2019b; IIHS, 2019c).

Effectiveness Concerns: This countermeasure is widely used. Its effectiveness has been examined in a few research studies. Despite some positive research findings, the balance of evidence regarding countermeasure effectiveness remains inconclusive.

Further information about the known research, potential effectiveness, costs, use, and time to implement is available in Appendix A6, Section 1.5.
