Numerator
Number of persons observed using restraints
Methodology
NOPUS uses observational data collected at intersections, highway ramps, and parking lots. Four observers (each responsible for a different seat in the vehicle) report occupant restraint use.
Data by race and age are not reported because race and age are subjectively assessed by roadside observers and are, therefore, considered unreliable.
Interventions
Primary safety belt laws allow police to stop motorists solely for being unbelted.
Enhanced enforcement programs are added to normal enforcement practices and include publicity.
Safety belt laws mandate the use of safety belts by motor vehicle occupants.
This intervention includes: an assessment of personal health habits and risk factors; an estimation or assessment of risk of death and other adverse health outcomes; and, provision of feedback in the form of educational messages and counseling.
