Is the seller of a car responsible for a smog test pass and or repairs to pass a test prior to sale?
State of California The seller is required to provide the buyer
with a valid smog inspection certification at the time of the sale
or transfer. Smog certifications are good for 90 days from the date
of issuance. The inspection is not required on a transfer if a
biennial smog certification was submitted to DMV within 90 days
prior to the vehicle transfer date (a vehicle inspection report may
be required for proof of certification). Starting January 1, 2005,
smog certifications will not be required for transfers that occur
for any motor vehicle that is four or less model years old. A smog
transfer fee will be collected from the new owner.
