WASHINGTON – The number of U.S. traffic fatalities fell for the fifth year in a row in 2010, dropping 3 percent to its lowest level since 1949, according to estimates released by the Department of Transportation on Friday.
Fatalities fell from 33,808 in 2009 to 32,788 last year, despite the fact that Americans drove nearly 21 billion miles more in 2010 than in the year before.
That works out to about 1.09 deaths for every 100 million miles traveled, a major drop from 1972, when traffic deaths peaked at 54,589 and there were 4.33 deaths for the same number of miles traveled.
The trend has continued despite yearly increases in population, the number of cars on the road and miles driven. Since 2005, traffic fatalities have fallen by 25 percent, with a particularly large drop of almost 10 percent in 2009.
“I think people really are aware of safety, and people really are aware of personal responsibility,” said Transportation Secretary Ray LaHood. “These things will only increase our ability to reduce deaths on the road, so I’m certainly encouraged by the trend.”
LaHood pointed to public awareness campaigns, including those that advocate seat belts and discourage distracted driving, graduated driver’s license programs that give teen drivers limits such as nighttime curfews and a maximum number of passengers, harsher drunken driving laws and more effective law enforcement as factors in the drop.
Regionally, the largest decline in fatalities was 12 percent in the Pacific Northwest states of Washington, Oregon, Montana and Idaho, followed by an 11 percent drop in California and Arizona, according to the DOT. Fatalities increased in the Great Lakes region and in the Northeast.
Safer road design and improved vehicle safety are also major factors in the reduction in fatalities, said Barbara Harsha, director of the Governors Highway Safety Association.
“With safer roadways there are improvements like rumble strips, median barriers and pavement markings,” Harsha said. “With vehicles, air bags and stability control have been particularly key.”
After dropping in the first two quarters of 2010, traffic deaths actually increased slightly in the third and fourth quarters of the year (by 1.6 percent and 1.8 percent, respectively), but Harsha said this likely isn’t an indication that the trend of fewer fatalities is reversing.
“That’s fairly typical because the third quarter is the warmer months,” she said. “More people are driving, there are more motorcyclists and so on. So that’s pretty predictable, and I think you see that every year.”
Roy Lucke, director of research at Northwestern University’s Center for Public Safety, said when new safety technology is introduced, it’s usually too expensive to put in most cars, but as technology has become cheaper, safety has become much more accessible to the average driver.
Side airbags, antilock brakes and traction control are all examples of now-common safety features that used to be limited to only the most expensive vehicles, he said.
