Three fatal wrecks happened within 24 hours in the Tennessee Valley; two in Chattanooga and one on Cagle Mountain in Sequatchie County.

Officers on the highway worry for drivers' safety this holiday season.

The Tennessee Highway Patrol says there have been 55 fatal wrecks in Hamilton County, which is up from last year.

After Monday’s fatal wrecks, they urge drivers to be more defensive on the road.

"Everybody is driving more offensively. We have got to get back to defensive driving,” THP Lt. John Harmon said.

The month of December as a whole has been a dangerous time on the road in the Tennessee Valley.

"In our region, our 12 counties, we have worked 60 property damage crashes since 6 o'clock this morning. We have worked 16 injury related crashes and we have unfortunately have worked one fatality crash,” Harmon said.

Lt. Harmon says the holidays are a busy time on the road.

"Keep that in mind as they travel to their destinations. Whether it be in Chattanooga or in another community,” Harmon said.

The two crashes in Chattanooga make 44 fatal wrecks reported in 2019, which is 17 more than last year.

Chattanooga police report 18 fatal wrecks in 2017 and 27 in 2018.

Lt. Harmon hopes drivers will learn from Monday’s horrific accidents.  

"Hands on the steering wheel, eyes on the road. You know, be aware of these incidents so you can arrive alive,” Harmon said.

Harmon says drivers need to be sure to wear their seat belts and always have a designated driver if you plan to drink.
