Many drivers are not aware that there is a scoring system that is used to rate the likelihood of a truck to be selected for a DOT inspection. This system is known as the ISS score (Inspection Selection System). The CSA scores that we receive in the DOT inspection feeds into and creates the ISS score.
The ISS score helps roadside commercial vehicle enforcement officers make quick decisions on whether or not a truck should be inspected or not. The CSA scores that we receive in the DOT inspection feeds into and creates the ISS score. The ISS score range from 1 to 100
Below is a chart of the ISS Scoring Breakdown
| Recommendation | ISS Inspection Value |
| Inspect (inspection warranted) | 75-100 |
| Optional (may be worth a look) | 50-74 |
| Pass (no inspection required) | 1-49 |
How does this affect you the driver?
Each time you pass a DOT inspection site, if your company’s ISS score is above 50 the inspector may elect to pull you over. If your company’s score is, over 74, they HAVE to pull you over and the inspector is going to look HARD at everything!
Here are a few tips on we as a company can do to improve our score?
- Improve HOS by updating the correct driving/non-driving status
- Maintain the proper speed limit
- Keeping all inspections and services to the truck and trailer up to date
- Knowing where your Permit Book is and what information is in it
Warnings are not to be celebrated. They are equally as damaging as tickets being issued. Let us work together to lower our CSA violations so we can decrease our ISS score.
