During a Thursday morning stop in North Bryan County, Gov. Nathan Deal announced the addition of 60 commercial-vehicle enforcement officers to improve highway safety and help reduce motor-vehicle crashes in Georgia. The Georgia Department of Public Safety and the Georgia Ports Authority are partnering to fund this investment, weeks after a series of high-profile wrecks involving tractor-trailers on both Interstates 16 and 95, including one chain-reaction crash on April 22 that killed five Georgia Southern University nursing students on I-16 near the Highway 280 exit.
