Law enforcement in Tennessee and Kentucky are participating in a project to encourage safe driving as summer comes to an end.

Traffic is expected to increase during the Labor Day weekend. The Office of Highway Safety is working to raise awareness of impaired driving dangers and help law enforcement take impaired drivers off the highways.

The Highway Safety Office distributes federal grant money to increase law enforcement presence during designated holiday periods. The National Highway Traffic Safety Administration says high-visibility enforcement campaigns reduce impaired driving fatalities by as much as 20 percent.
