City Hall has decided to ban tuk-tuks and motorbike-pulled trailers from driving on Norodom Boulevard, according to a statement issued Thursday, though officials said Sunday that they did not know when the ban would go into effect. "Norodom Boulevard is a main road that must be regulated," said Keo Savin, director of land transport at the Ministry of Public Works and Transport. Phnom Penh Governor Kep Chuktema called the banned vehicles "anarchic" and said officials were looking forward to implementing a broader traffic safety campaign on August 1.
