A Clean CSA Score Does Not Mean a Clean Record
The score expires. The record does not. Here is what an underwriter can still pull years after a violation drops out of your CSA math.
Two different files, two different clocks
A carrier calls in with a screenshot of a clean public profile and expects a clean quote. The renewal comes back higher anyway. Nothing went wrong in the quote. The carrier and the underwriter were reading two different files that run on two different clocks.
The Safety Measurement System is a prioritization tool. FMCSA built it to decide which carriers get an intervention this month, so it looks at the previous 24 months of roadside inspection data and state reported crashes, and it updates monthly. Violations inside six months count three times, six to twelve months count twice, one to two years count once, and after two years they do not count at all. Our guide on what a CSA score actually does to your premium walks that math out in full.
Underwriting is not a prioritization tool. It is a pricing decision on a multi year record, and the source data behind CSA sits in FMCSA's Motor Carrier Management Information System long after the score stops counting it.
What a PSP report still shows after the score forgets
The clearest proof is the Pre-Employment Screening Program. FMCSA sends its PSP contractor a monthly MCMIS extract containing driver crash data from the previous five years and inspection data from the previous three years. So a violation that fell out of your CSA calculation twelve months ago can still sit in a report that any carrier, and by extension anyone evaluating your drivers, is able to pull before a hire.
Same event, three different lifespans. Two years in the score. Three years in the inspection history. Five years for a crash. When a submission and a set of loss runs disagree with a screenshot, this is usually why.
No alert is not the same as no problem
There is a second reason a public profile looks calmer than the record behind it. Under Section 5223 of the FAST Act, FMCSA removed alerts and relative percentiles for property carriers from the public display of SMS on December 4, 2015, and it remains barred from publishing them until the correlation study and the Act's reporting requirements are satisfied. Section 5223(c) kept the absolute measures public, and the underlying inspection and crash data never left.
So what got hidden is the comparison, not the events. A broker compliance desk or an insurance data service reads the raw inspections either way. Seeing no alert on a public page tells you very little about how your file reads where it matters.
Sometimes there is no percentile at all
A blank category is easy to misread as a good one. SMS only assigns a percentile when a carrier clears a data sufficiency standard, and the bar is different per category. Hours of Service Compliance needs three or more inspections. Vehicle Maintenance needs five or more vehicle inspections. Unsafe Driving and Controlled Substances and Alcohol also require at least one roadside violation in that category within the past twelve months, so older violations alone leave the category unscored.
FMCSA has approved changes that widen that last rule. Under the updated methodology approved in a Federal Register notice dated November 20, 2024, the twelve month standard extends to Hours of Service, both Vehicle Maintenance categories, Hazardous Materials and Driver Fitness, meaning a carrier whose violations in those categories are all twelve months or older would not be assigned a percentile at all. FMCSA has not announced a launch date and says carriers should keep using the current SMS site until the updated system is in effect. When it does land, more carriers will show blanks, and a blank is not a clean bill of health.
What actually moves the renewal
Underwriters price the pattern, not the percentile. Repeat violations of the same type across different drivers read as a supervision problem rather than a bad day. An out of service order carries more weight than a paperwork citation. A crash inside the five year PSP window still gets asked about even when the CSA math has dropped it.
Three things are worth doing before you shop. Pull your own PSP driver records and your full SMS profile, since property carriers can log in and see the percentiles the public cannot. Challenge genuinely wrong data through DataQs rather than waiting for it to age out. And watch your renewal timing, because a violation crossing the six month mark drops from triple weight to double, which is a real difference on a small fleet where one inspection swings a category. The rest of how a CSA score prices into a truck insurance premium sits alongside the commercial auto liability limits you actually run.
Ready for a better rate?
If your last renewal did not match how clean you thought your record was, let us pull the file the underwriter pulls and quote it honestly. Get a truck insurance quote in under a minute, or call or text 423-264-4255 and we will walk your CSA profile and your loss runs together before anything goes to market. It also helps to know how much commercial truck insurance costs going in so you can tell a real quote from a teaser.
Common questions
How long do CSA violations stay on my record?
Two answers, and they are both right. In the Safety Measurement System a violation counts for 24 months, at triple weight under six months, double from six to twelve months and single from one to two years, then it stops counting. In FMCSA's underlying MCMIS data it lasts longer, which is why a Pre-Employment Screening Program report carries three years of inspection history and five years of crash history.
Why is my CSA category blank instead of showing a score?
A blank usually means you have not met the data sufficiency standard for that category, not that you scored well. Hours of Service Compliance needs three or more inspections and Vehicle Maintenance needs five or more vehicle inspections before SMS assigns a percentile, and Unsafe Driving plus Controlled Substances and Alcohol also need a violation in the last twelve months. An underwriter treats a blank as missing information, not as a good result.
Can an insurance company see CSA data that the public cannot?
Yes. FMCSA removed property carrier alerts and relative percentiles from the public SMS display under Section 5223 of the FAST Act, but the absolute measures stayed public and the raw inspection and crash data never went away. Insurers and data services work from that record, so a quiet public page does not mean a quiet file.
Should I wait for a violation to age out before shopping my truck insurance?
Sometimes a few weeks help. A violation crossing the six month mark falls from triple weight to double, which can move a category on a one to five truck fleet. It is not worth going a year without shopping though, since the record still shows the event. Call or text 423-264-4255 and we will look at your timing first, or get a truck insurance quote and we will tell you straight whether waiting is worth it.
