/ɒn ðə spɒt faɪn/ – Phrase
Definition: Tiền phạt ngay lập tức.
A more thorough explanation: a type of financial penalty that police and other officials can issue to punish people for certain offences without the usual legal procedures. Such fines must be paid immediately. If not, the person issued with the fine might face prosecution.
