TAMPA — The chief inspector for Hillsborough County's Public Transportation Commission was arrested early Saturday and charged with driving under the influence, records show.

Mario A. Tamargo, 69, of Tampa was arrested shortly before 4 a.m. near the intersection of Gunn Highway and Beaty Grove Drive, according to a Hillsborough County Sheriff's Office report.

A sheriff's deputy saw Tamargo's GMC Yukon heading west on Ehrlich Road at 25 mph in a 45 mph zone, weaving in and out of the lane and almost striking a concrete curb, the report states. During a traffic stop, the deputy noted Tamargo's breath smelled of alcohol, his eyes were bloodshot and he swayed as he stood, the report states.

According to the report, Tamargo performed poorly on sobriety exercises and refused to provide a blood alcohol sample. He was released from the Hillsborough County Jail about noon on Saturday after posting $500 bail.

Tamargo is a retired Hillsborough sheriff's deputy who later took a job with the PTC. The commission regulates vehicles for-hire in the county such as cabs, limos and tow trucks. The agency sets rules for operators, inspects their vehicles and handles complaints from the public.
