Are you legal to sell a car as is without a smog test in California?

In California, you can sell a car "as is" without a smog test, but certain conditions apply. If the vehicle is a model year 1975 or older, it is exempt from smog requirements. For newer vehicles, the seller must provide a smog certificate unless the car is being sold to a family member or the car is inoperable. It's advisable to disclose any known issues to avoid potential legal issues.
