You said that this individual's inability to get a job requiring a CDL is because he failed to act on a citation. I allege that he did nothing deserving a CDL license suspension, and that the courts resorted to inappropriate measures.
The arrest warrant was not issued because California now replaces the warrant with the collections agency. There's no doubt the OP now has an adversely affected credit report.
This too shows a miscarriage of justice: things requiring credit reporting should be those things that were purchased on credit. But in California's schizophrenic criminal justice system, Things that shouldn't cause a suspended license do, and things that shouldn't cause a blacklisted credit report do.
Rather than trying to find other, more appropriate means of fixing California's damaged economy, the California legislature sucks money from unsuspecting victims, such as a young person riding a scooter without a helmet.
Rather than trying to save a scooter-riding taxpayer brain damage by making him wear a helmet, the California legislature actually inflicted very substantial damage in the form of destruction of job opportunities, a screwed up credit report, and an obscene, absurd fine, which will likely exceed $500 when the Legislature-induced nightmare ends for him.
