WASHINGTON -- There's been a decline in drunken-driving deaths in 32 states.

The government said nearly 13,000 people were killed last year in crashes in which the driver had a blood alcohol concentration of 0.08 -- the legal limit in the United States -- or higher.

That's a drop of roughly 4 percent from 2006, when almost 13,500 people died on the highways.

California led the decline with 117 fewer alcohol-impaired driving deaths last year. Texas had 108 fewer deaths and Arizona's fatalities dropped by 63.

At the same time, alcohol-related fatalities among motorcycle riders increased in half the states.

A total of 1,621 motorcyclists were killed in alcohol-impaired crashes in 2007, up more than 7 percent from the year before.
