That no turn on red law hasn't taken effect yet. You need to stop before the line count to 3 one thousands of a second. Move forward stop again count 3 one thousands of a second, check then go. And you're fine. If you do one stop you are legally liable for a ticket.

You did a yield check? That's illegal. The cameras can check to see if your speed is at 0 mph and if it isn't they can ticket you.

If wa state ever does pass the law no right turn on red. The city will have to effectively enforce it. Considering how bad they are at enforcing normal driving rules I highly, highly doubt they'd ever get close to enforcing this one.

Even when intersections have no turn on red signs for driver safety people still are dumb affes and run them.
