    Two new guides — SMS scoring math and crash preventability

    The guides hub grew from one article to three. "How CSA SMS Scoring Actually Works" walks the whole pipeline — severity weights, the OOS +2 adder, time weights, normalization, safety event groups, and intervention thresholds — so you finally know what each violation costs and when it fades. "Crash Preventability Determinations (CPDP)" covers which crash types qualify, how to file through DataQs with the police report, and what a Not Preventable finding changes in SMS and PSP. Both with key-takeaways boxes and accordion FAQs.

A note from the builder

Why I built VioCodes

We all know the pain of digging through SMS Appendix A every time you need a code, its severity weight, or BASIC. And officers sometimes write codes that aren't even in there.

You're not always at a desk — you're at the yard, in the cab, on the road, or talking to a driver right after an inspection. Pull out your phone, type the code, get the answer.

Hit a code that's missing? Submit it for review and it gets added to the live list — so the rest of us can find it next time.

Help keep Appendix A fresh

Officers cite codes that aren't in any spreadsheet. Register a free account and submit them — everyone benefits next time someone searches.
