A good Samaritan who stopped to help after a motorcycle crash on New Kings Road was hit by a car while crossing the street, according to the Jacksonville Sheriff's Office.
The pedestrian is in critical condition at UF Health Hospital, police said.
The motorcyclist, who was traveling from Central Florida to Georgia, was seriously injured in the initial crash, which drew help from several passersby.
After Jacksonville Fire Rescue arrived, a 71-year-old man who had stopped to help was walking back to his truck, which was parked in the center grass median, and was hit by a Toyota Camry headed north on New Kings Road, police said.
The pedestrian was taken to UF Health with life-threatening injuries.
Jim Ringland, who was also traveling from Central Florida to Georgia, said the motorcyclist involved in the initial crash is his friend. Ringland saw the good Samaritan moments before he was hit.
"He was very helpful. (He) was there, was, like, 'Everybody OK?' And next thing I know, he was walking back to get his truck and all I hear is screech, thump," Ringland said.
The driver of the Camry, a 36-year-old woman, had her sons, ages 15 and 3, in the car with her. They were not injured.
Police said speed was not a factor in the crash and the driver of the Camry will not be cited because the pedestrian walked into her path.
"Of course, slow down. Be careful. Try to concentrate on the roadway. And also, as a pedestrian, you have to make sure the way is clear before you step out into that roadway," said JSO Sgt. Donald Washington Jr.
The Camry had visible damage to its windshield, and the motorcycle appeared to be a Can-Am Spyder and looked like as if it had caught fire.
Police said the motorcycle had been hit by a work truck about 11:45 a.m. Friday. They said the three-wheel motorcycle had been headed northbound on New Kings Road and had slowed to turn into the Kangaroo gas station at the intersection of Wagner Road when it was hit from behind by the work truck.
The rider was taken to UF Health with life-threatening injuries but was later upgraded to having serious injuries.
The 50-year-old driver of the work truck was not injured in the crash and was cited for careless driving, police said.
The two crashes closed two westbound lanes and one eastbound lane of New Kings Road from Gilchrist Road to I-295, but the road later reopened.
