Researchers said that if the gas price remains 4$ a gallon for at least one year in the United States, traffic death will drop to about one-third or 12,000 lives.

The University of Alabama at Birmingham’s Lister Hill Center for Health Policy, and David Grabowski at Harvard Medical School said the higher gasoline price the more benefit bring to the community in terms of accident, they said people would slow down while driving and go out less, which would drop the number of traffic accident significantly.

Almost 1000 deaths per month will drop if the gas price stays 4$ nationwide. They said.

“It is remarkable to think that a percent change in gas prices can equal lives saved, which is what our data show,” Morrisey said in a statement. “For every 10 percent rise in gas prices, fatalities are reduced by 2.3 percent. The effects are even more dramatic for teen drivers.”
