RENO, NV - Nevada Highway Patrol troopers are investigating a crash that blocked traffic on Highway 395 northbound at Golden Valley.

Troopers say it was a school bus that rolled with the driver and one pre-school student on board on northbound 395 Monday afternoon. Lanes were closed for about 90 minutes. The three-year-old was transported to a hospital as a precaution, as was the bus driver, but troopers say both are expected to be okay. The driver of a VW Jetta is not hurt.

Troopers say the driver of the Jetta hit one of the bus's tires, causing the bus to roll. That driver will be cited for failure to maintain a lane. Troopers say the crash isn't weather-related, and the driver doesn't appear to have been drinking or using other drugs.
