NORTH FORSYTH — A four-vehicle chain-reaction crash involving an on-duty Forsyth County Fire Department pickup truck made a mess Tuesday on Ga. 400 in north Forsyth but caused no serious injuries, authorities said.

Three of the four vehicles were found to have been following the one in front of them too closely as they came to Ga. 400-Hwy. 306 (Keith Bridge Road) crossing about 2:45 p.m., according to Robin Stone, a spokeswoman for Georgia State Patrol.

A 2006 Ford F250 pickup truck, marked as a county vehicle and driven by a 55-year-old on-duty fire department worker, reportedly rear-ended a 2007 Kia Sorento driven by a 64-year-old Cumming woman.

The impact caused the Kia to rotate and strike the rear corner of a trailer being pulled by a 2008 Ford Expedition. A 76-year-old man, who was driving, and a 77-year-old woman from Blairsville were in the Ford.

A fourth vehicle, a 2006 Toyota Tundra driven by a 54-year-old Dawsonville man, entered the median to avoid crashing into the fire department truck, striking a barrier.

All of the people in the vehicles involved were wearing seat belts, Stone said.

The county employee suffered minor injuries and did not accept transportation to a hospital.

The driver of the Kia was taken to Northside Hospital-Forsyth with what were described as non-life threatening injuries.

Stone said alcohol and drugs were not suspected in any of the drivers.

All four drivers were issued warnings: the county employee and the driver of the Kia for following too closely; the driver of the Expedition for no proof of insurance; and the driver of the Toyota for following too closely, failure to change address within 60 days and no proof of insurance.

“We do encourage drivers to make sure they keep a copy of their insurance card in their vehicle and another in their wallet or purse on them,” Stone said. “It makes it a whole lot easier when we are working wrecks and doing the paperwork if they have a card with them.”

Drivers who are insured can be ticketed for not having a copy on hand.
