A driver weaving his pickup on Highway 101 in Petaluma was arrested early Monday, suspected of driving drunk and traveling with several pounds of marijuana for sale, the CHP said.

A CHP officer spotted the Toyota Tundra at about 2:45 a.m. as it moved unevenly south on the highway near East Washington Street.

The officer pulled over the pickup and gave driver David Lee Thomas, 39, sobriety tests. Thomas was arrested on suspicion of driving drunk.

While checking his truck, officers found a plastic tub holding about 5 pounds of dried marijuana, vacu-sealed and ready for sale, CHP Officer Jon Sloat said.

Thomas of Redway in Humboldt County was taken to the Sonoma County Jail and booked on the DUI charge and on suspicion of possessing and transporting marijuana for sale.

He was released from jail later Monday after posting bail.
