AAA Carolinas said more than a million North Carolinians are expected to travel at least 50 miles between Friday and Tuesday.
The organization's president Dave Parsons said in a news release that higher confidence has led to more consumer spending and travel.
Meanwhile, the N.C. Highway Patrol will be focusing on impaired driving through Operation Firecracker, an effort launched by the Governor's Highway Safety Campaign.
Troopers will conduct checkpoints and saturation patrols in each county, attempting to combat the number of collisions that occur from impaired driving.
In 2016, the patrol investigated 111 collisions during the July 4 holiday in which alcohol was a contributing factor. Among those collisions, 76 resulted in an injury and four people were killed.
