Practice Relating to Rule 20. Advance Warning
On the basis of interviews with members of the armed forces and the Ministry of Home Affairs, the Report on the Practice of Malaysia states:
There are no written laws which require precautions to be taken in attack. However, during the communist insurgency, the imposition of curfews and announcements by the Department of Information to inform civilians to remain indoors or not to enter certain areas during certain periods served as an indirect warning to the civilian population.
