The 2018 NOPUS reported an 89.6 percent front seat belt use rate for the nation as a whole, which was essentially level with the 89.7 percent rate in 2017. However, it reflects a significant decrease in the seat belt use rate in the western region from 94.5 percent in...

Driving under the influence of drugs is a significant threat to public safety. Various substances can impair cognition, attention, coordination, and other brain functions critical to driving safety. Unlike alcohol, the mechanism for absorption, distribution, and elimination of drugs from the body, as well as cognitive and behavioral effects differ greatly. The use of cannabis, prescription drugs, and other drugs are increasingly prominent on our roadways, where 22.2 percent of the nation’s 37,133 fatalities in 2017 were related to drug-involved driving.

A speeding-related collision is defined as one in which a driver is racing, driving too fast for the conditions, or driving in excess of the posted speed limit. In the United States, speeding has been involved in nearly one-third of all fatal crashes for more than twenty years and is a leading contributing factor in traffic collisions. Speeding reduces a driver’s ability to steer safely around curves or objects, reduces the amount of time a driver has to react to a dangerous situation, and extends safe stopping distances. Nationwide there were 10,111 people killed in speeding-related...
