This countermeasure involves laws that specifically target the issue of drowsy drivers. With regard to drowsy driving, this type of law would permit drivers to be prosecuted for vehicular homicide if they have not slept in 24 hours and they cause a crash in which someone is killed.
Effectiveness Concerns: Laws that specifically target drowsy drivers are not widely used, and this countermeasure has not been systematically examined. There are insufficient evaluation data available to conclude that the countermeasure is effective.
Further information about the known research, potential effectiveness, costs, use, and time to implement is available in Appendix A10, Section 1.2.
