I've reached out to Twitter Support and submitted an appeal, but it may take a week (or longer) for the bot to get reinstated. In the mean time, ca-dmv-bot is live and active on Tumblr (https://tumblr.com/ca-dmv-bot/) and here on Mastodon.
I'm hopeful that Twitter will reverse the suspension sooner or later. I'll try to keep in touch.
Thank you all for the support.
