What is Blackout Rule in War?
Blackout laws controlled the lighting of homes, factories, shops, and vehicles, including covering windows and turning off street lights. This included painting vehicle headlights black. The main purpose of the blackout was to reduce enemy air attacks. In fact, at night, city lights helped enemy pilots find their targets. For example, in the 1940s, the German army bombed British cities at night.
Before the declaration of war, the Blackout Law was imposed in Britain on 1 September 1939. It was made compulsory to cover all windows with heavy curtains, cardboard or black paint to prevent light from coming in at night. All street lights were switched off. In London, local authorities ordered that outdoor lights be turned off or dimmed. There were strict rules for vehicle lighting, as the glare from headlights could lead enemy aircraft towards populated areas or factories. In Britain, only one headlight was allowed on four-wheeled vehicles. Similarly, the bumpers and running boards of vehicles were painted white. In view of the dangers of driving at night, a speed limit of 32 km/h was imposed.
