What is the speed limit on the motorway when smog is present?

When smog is present, the speed limit on motorways is reduced to 90 km/h. This regulation is in place to enhance safety and reduce the risk of accidents under conditions of poor visibility caused by smog. Lowering the speed limit allows drivers more reaction time to respond to potential hazards and can help improve overall traffic flow in less-than-ideal weather conditions. The objective is to mitigate the dangers associated with reduced visibility while ensuring that all drivers can travel safely through affected areas.
