BERKELEY -- A motor home flipped onto its side and collided with a tow truck on eastbound Interstate 80 Sunday morning causing four people to suffer minor injuries, the California Highway Patrol said.

Shortly before 5:30 a.m., the CHP received a report of an injury collision blocking all lanes of eastbound I-80 in the vicinity of Gilman Street.

Responding officers located a 1976 Dodge motor home, 20-25 feet long, that had come to rest on its side in the roadway, and a 2006 Isuzu tow truck carrying a car that had jackknifed, the CHP said.

The tow truck came to rest on an embankment separating the highway from the Gilman Street off-ramp.

According to the CHP, the driver of the tow truck suffered minor injuries, and the three occupants of the mobile home complained of pain. The tow truck driver was transported to Highland Hospital, and the occupants of the mobile home were transported to Alta Bates Summit Medical Center.

The far right lanes of eastbound I-80 and the Gilman Street off-ramp remained closed for almost four hours while debris was removed from the roadway, the CHP said.

The cause of the collision remained under investigation, but the CHP arrested the driver of the motor home, identified as 46-year-old Fremont resident Laron Presley, according to the CHP.
