Two parked cars were struck by a city bus in Hartford.
It happened on Wethersfield Avenue around 5:30 a.m.
"All of a sudden, it hit one car, then one car hit the other car," said an eyewitness who only identified himself Kelvin.
Wethersfield Avenue was closed between Alden and Annawan Street for a brief period of time, according to police.
In addition to the two side-swiped cars, a fence in front of a non-profit agency was also damaged. The bus can to a stop after hitting a tree.
"The bus slid all the way up, ran into the park [and] hit the tree," Kelvin said. "The whole window came out."
Eyewitnesses said they couldn't believe what they saw.
"If he didn't stop the bus, he would've kept going and crashing into other vehicles," said Julio Colon, who saw the crash.
David Lee, general manager of CT Transit, said the driver was taken to the hospital for observation. He did not appear to have suffered any serious injuries. No one was on board the bus at the time and no one else was hurt.
Lee said the driver will take a federally mandated post-accident drug test. Until it's completed and he is medically cleared, he will be off the road. There was also no evidence that the driver fell asleep.
"[It] looked like he had a heart attack or a seizure or something," Kelvin said.
The crash damaged a historical wrought iron fence that lodged deep into a huge pin oak in Colt Park.
Officials said the fence was originally built in the 1800s and was part of an ongoing restoration project.
A camera was rolling on the bus at the time. The Department of Transportation said they will be looking over that footage for the investigation.
