According to the state of WA emissions FAQ, they use OBDII testing on all cars 1996 and newer. I believe every state that does emissions testing now does it first by OBDII and some allow you to take a secondary sniffer test. Most however do not. WI and IL here just recently cut back staff and hours at testing facilities since doing the OBDII scan is so much faster.
