In Tennessee's highway work zones, the bigger crash problem is not after dark. State records for 2025 show far more collisions happening in broad daylight, with roughly 1,515 work zone crashes logged during the day compared with about 746 at night. The figures come from the statewide TITAN crash database, which local police pulled into a snapshot and shared on social media on April 21, 2026.
The Sevierville Police Department shared an image of the TITAN output that lists 1,515 daytime work zone crashes and 746 nighttime crashes, along with seven daytime fatalities and eight at night, according to the Sevierville Police Department on Facebook. The tally only covers wrecks where the first harmful event is recorded inside the work zone boundaries in the state reporting system.
Why nighttime crashes tend to be deadlier
National research has found that work zones raise crash risk both day and night, but incidents that happen after dark are more likely to turn serious or fatal. Reduced visibility, higher prevailing speeds, and different nighttime construction operations all raise the stakes, according to a review of nighttime and daytime work zone safety from the National Academies of Sciences, Engineering, and Medicine.
State response and outreach
In Tennessee, agencies lean on TITAN data to decide where and when to lean on drivers. The Tennessee Department of Transportation used Work Zone Awareness Week to spotlight the human toll of these crashes, pointing to the previous year's statewide death count in work areas and noting that 16 people were killed and hundreds more were injured. The campaign urged motorists to move over, slow down, and treat every cone line like a live worksite, according to the Tennessee Department of Transportation.
The Tennessee Highway Safety Office and partner agencies say they use TITAN to flag the times and locations that see the most trouble, then focus enforcement and public education in those hot spots.
How drivers can reduce risk
Safety guidance for drivers is not especially glamorous, but it is consistent: obey reduced speed limits in work areas, follow flagger instructions, put the phone away, and leave extra room for lane shifts, heavy machinery, and workers on foot.
On the engineering side, federal work zone guidance points to tools that can help blunt the worst outcomes after dark, including better temporary lighting, end-of-queue warning systems, and truck-mounted attenuators that absorb impact when a driver fails to stop in time, according to the Federal Highway Administration.
Officials say TITAN's statewide crash numbers will keep shaping where troopers patrol and how agencies talk to drivers about work zone safety.
