Likewise, is there smog in California?

Smog Information. Currently, smog inspections are required for all vehicles except diesel powered vehicles 1997 year model and older or with a Gross Vehicle Weight (GVWR) of more than 14,000 lbs, electric, natural gas powered vehicles over 14,000 lbs, motorcycles, trailers, or gasoline powered vehicles 1975 and older.

Beside above, why is there so much smog in California? The reason so much smog forms there is because the city is in a low basin surrounded by mountains, with millions of cars and industrial sites spewing emissions into the air. But thanks to tougher state and federal air quality standards, L.A. residents can breathe easier than they've been able to for decades.

What is the difference between smog and fog?

Mist and fog are caused by water droplets in the air, and the only difference is how far you can see. Haze is the reflection of sunlight off air pollution, while smog is what happens when pollution causes low-lying ozone. When warm water in the air cools quickly, the droplets change from invisible to visible.

Why is Los Angeles air quality so bad today?

Why is LA so hazy?

When a “mysterious haze” first enveloped downtown L.A. back in 1943, panicked residents thought the Japanese had bombed Santa Barbara. In fact, the thick stew of pollutants was something altogether new: a chemical reaction between car emissions and SoCal sunshine, which later came to be known as smog.
