DETROIT — Driving is getting safer.
The number of traffic deaths nationwide dropped about 3 percent last year, and the rate of deaths per 100 million miles traveled tied a record low, according to government statistics.
But the number of people killed on the roads rose in two categories: Crashes involving big trucks and bicycles.
A total of 32,719 people died in U.S. crashes in 2013, down from 33,782 in 2012, according to figures compiled by the National Highway Traffic Safety Administration. That's about 90 deaths per day, compared with 92 in 2012.
People died at a rate of 1.1 per 100 million miles driven, tying a record low set in 2011. Deaths caused by drunken and distracted drivers also fell.
NHTSA Deputy Administrator David Friedman said the drop came because of safer vehicles, stronger laws and enforcement, and consumer education campaigns. Over the past decade, traffic deaths have dropped nearly 25 percent.
Electronic safety devices also played a role, said Transportation Secretary Anthony Foxx, who oversees NHTSA. For example, deaths in rollover crashes dropped last year at a higher rate than the overall decline largely due to stability control, which electronically controls the brakes and throttle to stop vehicles from overturning, Friedman said.
Advertising campaigns against distracted driving, such as one against driving while texting, helped bring that category down, the government said. The number killed in crashes with distracted drivers fell nearly 7 percent to 3,154.
