The police have no way to test whether or not emissions are over the limit. They have no way even to catch the "octopus vehicles"; if they grab them and give out a ticket, there's no way to make sure the ticket is enforced. Thus even "pollution citations" are no use.
由於缺乏專業訓練，目前警察單位無法檢測機車是否超過排放標準，也因此無法取締「烏賊車」，即使對冒煙嚴重的機車開了罰單，以目前交通違規罰單都無法確實執行罰則的狀況下，再多開一張「汙染」罰單也沒用。
