Thursday morning an Amador County Sheriff’s Deputy attempted a routine traffic stop on a vehicle with an expired registration tag. The vehicle failed to yield and a pursuit began. The vehicle headed southbound on Hwy 26 at speeds in excess of 90 miles per hour. Once across the Calaveras County line the Amador County unit was joined by Calaveras County Sheriff’s Department deputies. The Amador Unit ended his portion of the pursuit once he deemed that there was just too much risk to other citizens because of the metropolitan nature of the area to which the pursuit traveled. The pursuit was continued by Calaveras SO Deputies and the San Andreas Units of the CHP, along with CHP helicopter H20.
