EGREMONT — The diver of the vehicle that struck the post office in South Egremont will not be charged, according to Police Chief Brian Shaw.

Shaw said his department will, however, be filing a complaint with the Massachusetts Registry of Motor Vehicles to take action against the driver, whom police did not name because he was not charged.

He said an investigation determined the driver was not intoxicated or impaired by drugs when he struck the building about 7 p.m. Tuesday, crashing through the front wall and into the post office. The damage forced officials to close the post office Wednesday, but it reopened Thursday.

In the interim, customers had to drive to the Great Barrington post office to get their mail, Shaw said.

"Some people weren't happy they had to drive to Great Barrington," he said.

Shaw said the Postal Service is negotiating with a contractor to carry out repairs to the building. That, he said, may require another brief shutdown when the work is underway.

It wasn't the first time the building has been hit, he said, but this was probably the worst.

"I've seen several," Shaw said, "just in the past few years."
