Why these tools exist

Every California DUI case has the same handful of factors that drive the outcome: BAC level, priors, accident status, stop and chemical-test quality, county prosecution patterns, and a small set of statutory triggers (high BAC, child passenger, refusal, injury). The flagship case analysis on the homepage covers all of them in one comprehensive report. These narrower tools are for the specific question you actually came to answer.

If you just got arrested and have no idea where to start, the free written case analysis on the homepage is the right entry point. If you have a specific question (can I get this reduced, how much will it cost, when can I drive again, will my CDL survive), use the dedicated calculator that answers that question directly.

Every tool follows the same approach: short focused questionnaire, written report by email, real California law citations, no false hope and no doom-mongering, and the option to call (888) 271-6644 to speak with an attorney directly. Every tool is free.
