CITY Hall has urged traffic police to begin a crackdown on motorists who have not paid their road taxes. In an announcement issued last week, Phnom Penh Governor Kep Chuktema urged police to begin collecting fines from November 25. The road taxes are collected annually and range from 4,500 riels (about US$1.05) for some motorbikes to more than 1 million riels ($238) for some cars. Fines are equivalent to double the tax payment.
