They connect your car to a machine that monitors tailpipe pollutants. You must pass emission testing unless you own a hybrid, diesel, electric, or a car from 1975 or older.

Smog check stations are officially called "emissions testing sites," and they are required for all cars in several states, including California. You just need to take your car to an emissions testing site every 2 or 3 years. The attendant will run your car in a closed room and test the resulting emissions to ensure they meet standards.
