Illinois carrier data includes figures for insurance cancellations and coverage lapses, drawn from a set of motor carriers operating in the state. The insurance cancellation rate is reported as 3.66, based on data from 89 carriers. Coverage lapse transitions are recorded separately at 3.66, sourced from 89 carriers. These measures reflect distinct aspects of carrier insurance status within Illinois and are tracked independently of one another in this index.
| Measure | Rate | Carriers | Insured base |
|---|---|---|---|
| Insurance cancellations | 3.66 | 89 | 24,294 |
| Coverage lapses | 3.66 | 89 | 24,294 |
It is a consistent sample, not a census; rates are comparable across periods and geographies but are not national totals. Rates are per 1,000 insured carriers domiciled in the state and are not adjusted for state size beyond that denominator.
Facility counts are derived from the EPA Facility Registry Service, a registry of environmentally permitted sites rather than a census of shippers.
