State officials say six people died in traffic accidents over the Labor Day holiday weekend.
The Alabama Department of Public Safety said state troopers investigated fatal crashes in Mobile, Elmore and Lauderdale counties.
Authorities consider the holiday travel period as 12:01 a.m. Friday to midnight Monday.
Sgt. Steve Jarrett says a preliminary investigation has shown that seat belts were available to three people who died in crashes, but only one victim was using one during a crash. Jarrett says the other three victims were riding bicycles and an ATV.
