Police will not accept documents from the international trade and industry ministry (Miti) as a valid movement permit for interstate travel for the four-day period from July 18-21.
Inspector-General of Police Acryl Sani Abdullah Sani said the ban followed the detection of an increased number of vehicles on the highways over the past two days.
“All roadblocks at state borders have been directed to increase enforcement and will not accept Miti documents as a valid movement approval.
“This is to avoid irresponsible parties from misusing the Miti permission letter as approval to cross states to celebrate Hari Raya Aidiladha,” he said in a statement.
However, he said the ban did not apply to emergency matters with police permission as well as health matters, including vaccinations.
He said anyone found violating the ban would face stern action without compromise, adding that the public had been advised to play a role in flattening the curve of the Covid-19 pandemic.
