As part of the campaign, the State Highway Patrol has increased its presence across North Carolina to stop or discourage unsafe drivers.
NCDOT has also suspended most road construction projects with lane closures, to reduce traffic congestion during the busy holiday weekend.
The program will run through July 10.
In the first four months of 2022, some 127 people were killed and 275 were seriously injured in impaired driving crashes in North Carolina, a NCDOT news release said. Since 2018, more than 70 people have been killed in crashes during Operation Firecracker enforcement periods.
