When a novice teen driver dies in a crash, odds increasingly are that there is another teenager in
For more than a decade, states have been imposing restrictions on teenage drivers that likely deserve credit for an overall decline in teenage traffic fatalities. But a study released Thursday shows that 15- to 17-year-old drivers are almost eight times more likely to get into a fatal accident while carrying two or more teenage passengers.
The analysis of 10 years of national traffic data notes that the 30 percent increase in deaths when other teens are present came at "the same time text messaging exploded in American society."
"We can't scientifically state that there's a direct link between these two things yet, but it seems reasonable to suspect a connection," said Russell Henk, a researcher at the Texas A&M Transportation Institute (TTI) who wrote the study.
Drivers age 19 and under are three times more likely to die in accidents, and traffic fatalities are the leading cause of death in that age group.
From 2002 to 2011, the number of novice teenage drivers in fatal accidents dropped by 60 percent, but the percentage of fatalities that occurred when other teenagers were in the
The District of Columbia and 47 states have adopted graduated licensing programs that put specific requirements on teenage drivers, including a restriction on the number of passengers they can carry. All states except Vermont and Nevada limit teen driving overnight.

Virginia, for example, permits no passengers under age 18 for the first year. Maryland allows no passengers under the age of 18 for the first five months. All three Washington area jurisdictions ban cellphone use by novice teenage drivers, as do 35 other states, and texting by all drivers is outlawed in the District, Maryland and Virginia.
The graduated licensing schemes lift restrictions as drivers age and gain experience, an approach born out by the study's comparison of 15- to 17-year-olds with drivers in the next age group, 18 to 24. While deaths with teen passengers on board increased each year among the younger group, it declined over 10 years in the older group.
"Novice drivers (15 to 17 years old) are at a distinct disadvantage, not only because of their limited driving experience, but also because of their incomplete
Less capable of correctly assessing risk, those teenagers are more easily distracted and more likely to take risks when other teenagers are in the vehicle, the report said.
