ROCKLAND — A 79-year-old woman was treated at Penobscot Bay Medical Center Saturday after being struck by a Kora Temple Shrine go-cart during the Maine Lobster Festival parade.

At about 10:23 a.m. Saturday, the go-cart drove onto the sidewalk on Main Street near AutoZone and struck the woman, as well as a 43-year-old man and a 9-year-old boy, Deputy Chief Wally Tower of the Rockland Police Department said Saturday afternoon.

Rockland emergency medical personnel treated the man and the boy, who refused to be taken to a hospital, according to Tower.

Tower said he had minimal information, and did not have names of the victims or the name of the driver, who was not detained.

The parade stopped for about 20 minutes before proceeding, he said.

The go-cart crash, which remains under investigation, is not the first to occur at a Maine parade. In 2012, a member of the Cairo Shriners of Rutland, Vermont, suffered a head injury during a Shriner parade in Bangor when he apparently gave the tiny motor-powered car too much gas and ran into the flatbed trailer from which it and other vehicles had been unloaded.

In October 2011, Shriner Marvin Tarbox Jr., 59, of Hancock died after a go-cart accident at the Damariscotta Pumpkin Fest Parade in Newcastle. The Lincoln County Sheriff’s Office said that a ramp that carried the go-carts over an SUV apparently failed while Tarbox was driving over it. His go-cart then flipped over and toppled onto the pavement, where he was struck by at least two other go-cart drivers, according to a previously published report.
