Yes, it says it’s false. Here’s the pertinent line:
identifies whether they may be impaired and prevents or limits motor vehicle operation “if an impairment is detected.”
That’s called a killswitch.
On the law itself, it’s Section 24220 - b - 1 - a - ii AND 24220 - b - 1 - b - ii
Just a reminder that fact checkers blatantly lie, and will even tell you they’re lying. It takes like two minutes to fact check laws like this.
By the definition of the above tweet (which is what the article is talking about) there is no kill switch.
