DETROIT (AP) — The number of traffic deaths nationwide dropped just over 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 highways 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. Distracted driving and drunken driving deaths also were down.
