HAMILTON -- A jackknifed tractor trailer carrying mail shut down Route 195 eastbound in Mercer County as the morning commute got underway.

A New Jersey State Police spokesman said the driver of the truck lost control at 4:15 a.m. trying to avoid another vehicle, and hit the guardrail in the median just east of exit 3 for Hamilton Square.

As of 6:30 a.m., all eastbound lanes were reopened.

It's the second crash on a major New Jersey highway to start a commute in as many days. A small school bus caught fire along the southbound Garden State Parkway around 3 p.m. Thursday, closing all of the lanes near Route 22 in Union for a time. Only two lanes were available for the remainder of the afternoon commute.

Seven child passengers and a driver escaped the bus without injury, according to State Police.
