The driver, whom Kates identified only by her first name, Molly, was thrown from the carriage onto a windshield. She was taken to Hahnemann Hospital with possible head injuries, police said.
She was feeling much better Saturday afternoon, said Kates, who said he had visited Molly in the hospital
"She is doing great and in good spirits," Kates said. "All of the tests, they all came back negative. She has some lacerations and scars, but she's more concerned about the horse than anything else."
Dutch, a 9-year-old draft horse, suffered a leg injury, said Kates, but is expected to recover.
"He's in vet care and he was eating and putting weight on the leg, which are both good signs," Kates said.
No other people were hurt.
Dutch has been with the company for three years, Kates said, and had never been involved in an accident.
Police corralled the animal within a block of the accident.
"He's truly a docile animal that doesn't typically spook," Kates said. "And it's odd to think he would run through that intersection. He's been at that intersection a thousand times."
No one is expected to be charged, police said.
In April 2010, three people were injured when a car rear-ended a horse carriage at a traffic light near Independence Hall, causing one carriage to strike two others. Two of the drivers were flung from their carriages and suffered head injuries.
In 1999, two carriages collided near Fourth and Market, ejecting some passengers but hurting no one. In that incident, police believed the horse was spooked by a passing truck.
In response to Friday's accident, the Philadelphia-based Peace Advocacy Network, a group that strives for "the absence of violence in the lives of people and animals," said it would be holding a protest next Sunday between Chestnut and Market Streets, calling for a ban on all horse-drawn carriages.
