Most studies of teenage motor-vehicle crashes and injuries have focuss
ed on drivers. However, deaths of 13- to 19-year-olds as passengers ar
e nearly as common as teenage driver deaths (2,131 vs. 2,355 in 1993),
and teenage passenger death rates are much higher relative to rates f
or older people than is the case for driver deaths. The deaths of both
teenage drivers and passengers, compared with deaths of older motor-v
ehicle occupants, are more likely to occur at night, and in smaller an
d older cars. Two-thirds of teenage passengers killed in 1993 were in
vehicles driven by other teenagers. More teenage passenger deaths occu
rred in vehicles driven by 16-year-olds than any other teen age, and b
oth male and female 16-year-old drivers had greatly elevated rates of
teenage passenger deaths in their vehicle per licensed driver and per
mile driven compared with older teenage drivers. Countermeasures inclu
de night driving curfews and restrictions on teenage passengers in the
vehicles of newly licensed drivers, a feature of New Zealand's gradua
ted licensing system that has reduced teenage motor-vehicle injuries i
n vehicles driven by 15- to 19-year-olds.
