Alabama and four other Southern states are working to slow down speeding drivers.
Beginning tomorrow, a week-long effort called 'Operation Southern Shield' aims to make roads safer.
State troopers in Alabama, Tennessee, Georgia, Florida and South Carolina will be encouraging drivers to slow down. That could mean lots more blue lights and speeding tickets.
The goal is to bring down the number of deadly car crashes.
According to the National Highway Traffic Safety Administration, speeding killed more than 10,000 people in 2016. NHTSA says speed was a factor in 27 percent of deadly car crashes in the US.
