Highway 49 just south of the Amador County line in Calaveras County was described as a battle field last evening after a single vehicle rollover. The collision occurred around 6:05 pm in the curves as a Honda Passport drove toward Amador County. Once on scene, fire personnel called for five ground ambulances, three of which responded from Amador County, and 2 helicopters for airlift from Sutter Amador Hospital. Stretchers for the five victims lined the north bound lane of traffic. None of victims spoke English, further complicating rescue efforts. The collision caused traffic backups for both northbound and southbound until nearly 8 pm. The accident is under investigation by the San Andreas Unit of the CHP.
