Two boys were hospitalized Saturday after the all-terrain vehicle they were riding collided with a parked tractor-trailer.

Forsyth County Fire Capt. Jason Shivers said the collision happened about 6 p.m. at 7614 Majors Road.

He said a 9-year-old boy was taken to Children’s Healthcare of Atlanta at Egleston with serious injuries, which included a nearly severed arm.

His 3-year-old passenger was taken to North Fulton Hospital in Roswell with what was described as head pain and a cut ear.

Shivers said the children drove underneath the tractor-trailer.

The incident was perhaps the most serious of the July Fourth weekend in Forsyth County.

Shivers said the department received 123 calls between 12 a.m. Friday to 12 a.m. Tuesday, which is not unusual number for a holiday weekend.

Shivers did note, however, that there no serious water-related emergencies or reports involving fireworks.

Investigators are still trying to determine what caused a house fire about 5 p.m. Sunday at 5415 Millwood Road off Hwy. 306 in north Forsyth.

“It will be a heavy loss fire and no one was home at the time,” Shivers said.

Forsyth County Sheriff’s Capt. Frank Huggins said the weekend was quiet for law enforcement.

The same was true for the Georgia Department of Natural Resources, which monitors Lake Lanier.

According to representatives with the DNR's law enforcement division, there were no significant incidents locally over the holiday weekend.

Overall, the Georgia State Patrol responded to 2,548 crashes, which resulted in 699 injuries and 10 deaths.

The state’s holiday crash count was higher than predicted, while injury and death totals were lower.

Going into the weekend, the state patrol estimated there would be 2,072 wrecks, 999 injuries and 18 deaths.

State patrol officials in Troop B, which encompasses five different posts including Cumming, responded to 256 incidents.

Those resulted in 89 injuries and one fatality, which occurred in Blue Ridge.
