The smog in 1991, particularly notable in cities like New Delhi, was primarily caused by a combination of industrial emissions, vehicular pollution, and crop burning in surrounding agricultural areas. Weather conditions, such as temperature inversions, trapped pollutants close to the ground, exacerbating the situation. Additionally, rapid urbanization and inadequate regulatory measures contributed to the severity of the smog crisis. The combination of these factors led to significant air quality deterioration during that period.

In California, vehicles manufactured in 1991 typically require a smog check unless they are classified as exempt. For example, vehicles that are 1975 model year or older are generally exempt from smog checks. Additionally, certain electric vehicles and hybrids may also be exempt. It's important to verify the specific regulations or any changes that may apply to your vehicle.
Particulate carbon in the air causes smog and can cause respiratory distress.
