Both start on the cancellation date, not when you notice. **Licensing.** CSLB requires an active license to have a certificate of workers' compensation insurance (or https://plumberspro.co/faq/how-does-my-x-mod-affect-my-workers-compensation-premium https://plumberspro.co/faq/how-does-my-x-mod-affect-my-workers-compensation-premium Fri, 23 Oct 2026 12:00:00 GMT Workers' Compensation Insurance Your X-Mod is a multiplier applied to your workers' compensation premium, so it moves the premium by the same percentage it sits away from 1.00. A mod of 1.25 raises your premium about 25 percent; a mod of 0.80 lowers it about 20 percent.

A commercial auto policy insures the vehicle, not the contents.

Nothing in the CSLB license rules tells you which kind of auto policy to buy, and the customers who hire you rarely check. The reason is the carrier.
