※ 引述《marathons (往 Gilroy 天天發車)》之銘言： : 若是通知單有註明 "TEST ONLY"則必須到掛有 "TEST ONLY"的SMOG檢 : 驗站去作，理論上 "TEST ONLY"是被DMV 隨機抽到的，其實很可能是 : 曾有SMOG未過的前科或較老舊車輛容易被指示去 "TEST ONLY"站。在 : "TEST ONLY" SMOG Check檢驗站不允許修車，所以通常 "TEST ONLY" : 的SMOG檢驗費較貴些，因為他們不能賺修車改善排氣的錢。 : 這是加州 SMOG Check 系統目前的鳥規則，我以前的舊車就曾被叫去 : "TEST ONLY" ，多付幾十元作完全相同的檢驗，即使我那老車排氣每 : 次都輕鬆通過檢驗標準也要被欺負，我認為這是歧視老車的惡行。 From DMV website: High Emitter Profile - The majority of vehicles directed to Test-Only stations are selected by application of the High Emitter Profile (HEP), which identifies the vehicles most likely to fail their Smog Checks. The High Emitter Profile (HEP) uses data from several different sources. Some of it comes from the state Vehicle Identification Database (VID), which collects data from each Smog Check performed in California. The VID is used by the Department of Motor Vehicles (DMV), BAR, and other government agencies. In addition, general vehicle data such as make, model-year, vehicle miles traveled, and engine size help define the HEP. This information is used to determine which vehicles are most likely to fail their Smog Checks, especially at Gross Polluter levels--at least two times the emissions level allowed for a particular vehicle. Two Percent Randomly Selected - As required by State law, two percent of the vehicles in the Enhanced Areas are also directed to Test-Only stations for their Smog Checks. These vehicles are selected randomly to evaluate the overall effectiveness of the Smog Check Program. 結論: 大部份會收到test-only的車子，是DMV認為「比較容易fail smog test」的車子但是在高汙染地區有2%的車子會被隨機抽中test-only，做為對照組及資料分析用 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 158.140.1.28
