A young Rohnert Park man was arrested early Saturday on suspicion of driving at high speed while under the influence on northbound Highway 101 just north of Petaluma Boulevard North.

At 4 a.m., CHP Officer Dave Stewart, using a hand-held LIDAR speed detector, clocked a 2012 Infinity G37 traveling at 145 miles an hour, the CHP said. The car was being driven by David Adler, 21.

The CHP said the vehicle was equipped with a radar detector and immediately slowed down after being detected. Adler was stopped for speeding and later arrested on suspicion of DUI.

The car Adler was driving was registered to someone else with the same last name, the CHP said.
