Five people were hospitalized after a New York City-bound Megabus crashed into a guardrail on I-95 Friday afternoon, police officials said.

The bus, which had come from Washington, D.C., drove onto the right shoulder of the interstate and then smashed into a guardrail at about 3:39 p.m., Maryland State Police said in a statement.

The driver told police he believed the bus had had a mechanical failure, the state police said.

Of the 68 passengers on board and the driver, 5 were hospitalized at Harford Memorial Hospital as a precaution, police said. No further injuries were reported.

I-95 was shut down as the investigation ensued, police said.

Megabus released a statement Friday afternoon recapping the accident, and adding, “Safety is megabus.com’s number one priority,” a CBS affiliate in Baltimore reported.
