The annual Sturgis Motorcycle Rally is underway in the Black Hills of western South Dakota.
Several hundred thousand people are expected this year, and public safety officials are reminding bikers and other motorists to stay alert.
In recent years, the most deadly rally was the 75th anniversary event in 2015, which drew a record 739,000 bikers. During that rally, 14 people died in motorcycle wrecks throughout the state.
Officials say there were eight traffic fatalities last year.
The rally began its 10-day run Friday.
