Firefighters are on scene of a Metro Schools bus crash involving children in Antioch, a fire department spokesperson said late Friday morning.

Crews responded at about 11:35 a.m. to Humber Drive and Torbay Drive after a bus transporting nine students from Overton High School slid off the road into a ditch and tipped with children on board.

No injuries were reported and children were safely unloaded from the bus, then transferred into another bus to be taken home.

The crash is one of hundreds that snarled roadways in Davidson and surrounding counties late Friday morning after snowfall returned to the region causing slick roadways.

In Davidson County, Metro police spokesman Don Aaron said officers responded to 308 non-injury crash calls received between 7 a.m. and 10:30 a.m.

Late Friday morning, Nashville Fire Department spokesman Brian Haas said five vehicles were stuck in a pileup at bottom of hill at Tulip Grove Road and Rockwood Drive.

"No apparent injuries, but a mess, so avoid area," Haas tweeted.

Earlier in the morning a Metro Schools bus hit a mailbox in South Nashville at Tusculum Road and Shihmen Drive and about two others in that area got stuck on a patch of ice. No injuries were reported.

Metro police tweeted that road conditions in parts of South Nashville and its Midtown precincts were icy and asked motorist to be cautious when driving.

In Wilson County, city officials said Devonshire Drive, Willoughby State Boulevard and Pleasant Grove Road were impassable.

In Wilson County early Friday afternoon at least two school bus crashes were reported including one involving a West Wilson Middle School bus that crashed with another vehicle near the 900 block of N Mt Juliet Rd.

Mt. Juliet police said no kids were on board and no injuries were reported.

In Cheatham County two crashes along Interstate 24 just south of Pleasant View had traffic clogged in both directions.

Early Friday morning, Brentwood police were "overwhelmed" with the number of incoming calls, city spokeswoman Deanna Lambert wrote in an email. More than 40 accident calls came into Brentwood police during the 7 a.m. rush hour, Lambert said.

Dozens of motorists were stuck on the hill trying to get up Concord Road just east of Arrowhead Drive throughout Friday morning. To help out, three Brentwood residents, Tim Lawyer, John Bass and Kyle Piccirilly, decided to spend their morning helping the stuck drivers.

Lawyer, who lives at the top of the hill, said he works from home and couldn't stand to keep watching people get stuck outside. He took his truck and tow straps out to the road and spent more than two hours helping tow cars up the hill.

"I live here and I see it every year," Lawyer said. "This is just a little thin sheet of ice under here and if people get over in the snow they're usually OK, but not everyone makes it."

Bass and Piccirilly were driving through the area about 7 a.m. Friday and saw the drivers getting stuck. They spent the next few hours helping Lawyer push and tow cars up the hill.

"I was on my way to the gym this morning but pulled over after I couldn't make it," Bass said. "This is my workout I guess."

A city plow showed up about 10:45 a.m. and salted the roadway, eventually making it passable for motorists.

Earlier in the morning emergency crews shut down a portion of Highway 100 at Whippoorwill Hill in Williamson County to investigate a vehicle crash, authorities said and police in Nolensville were also asking motorists to avoid Clovercroft Road due to a traffic crash.

In Spring Hill, emergency crews reported multiple cars stuck on a hill at Lewisburg Pike and Thompsons Station Road East. The roads, they said, were not passable.

The City of Brentwood tweeted it had joined Williamson County and activated its Emergency Operations Center to Level 3 monitoring because of the inclement weather.

Level 3 is used when there is a "Declaration of State Emergency," according to the Tennessee Emergency Management Agency, This level describes an event or period when a serious emergency has occurred or the situation is deteriorating rapidly, and public warnings are being issued. Level 2 is considered a major disaster.

“We’re not seeing anything anybody else isn’t seeing, we're just monitoring roadways,” said Williamson County EMA Director Mac Purdy, referencing several injury-related and property damage crashes in that area. “Our primary concerns are any crashes that create backups and stranded motorists. Our fire and police are busy and we’re watching them to see if we need to stretch resources.”

Police are asking anyone who does not need to travel this morning to stay home.

This story was corrected to identify the students aboard the bus involved in the crash as being from Overton High School, not Haywood Elementary School. That bus typically serves Haywood Elementary.
