A 25-year-old Petaluma woman called the CHP at about 4 a.m. Sunday to report that a black, two-door Acura was following her BMW on northbound U.S. Highway 101 in Petaluma, CHP Officer Jon Sloat said.
The woman said the Acura's driver tailgated her, sped past her then slammed on the brakes, Sloat said. The driver also swerved at her car in an apparent attempt to run her off the road, he said.
The CHP broadcast a description of the Acura to nearby law enforcement agencies and a Sonoma County sheriff's deputy spotted the Acura and pulled it over near the Penngrove exit, Sloat said.
The CHP responded and arrested the driver, Carlos Gomez, 18, on suspicion of driving under the influence.
He was booked onto Sonoma County Jail for DUI, assault with a deadly weapon, driving without a license and driving without insurance, Sloat said.
