At about 5 p.m. Saturday, a caller to the fire department reported that the driver of an MBTA bus had experienced a full-body seizure while driving on Washington Street, down the street from the Fore River Bridge, Deputy Fire Chief Ed Fenby said.

When firefighters arrived, the bus was pulled over to the side of the road and a passenger was leaning over the driver’s seat and had his foot on the brake while the bus was still in gear, Fenby said Monday.

“My first thing was to put my foot on the brake and put it into neutral. I stood there and held the guy until the EMTs came,” passenger Richard Hiort said.

“Must have been horrible for him. It is like, this poor guy. And the look on his face. I don’t think I will forget it. He was so scared,” passenger Patricia Foster said.

The driver, 37, received medical treatment at the scene and was taken by ambulance to Quincy Medical Center, police said.

There were no reports of injured passengers or pedestrians, Fenby said.

The 911 call from a passenger went to State Police, who alerted Transit Police that a bus driver was in distress and that the bus was pulled over safely to the side of the road.
