License Class is a field that was completed appropriately in 90 percent of the reports reviewed. This field was incomplete in 13 percent of the reports submitted by State Police, which was the highest incomplete rate of the three submission types. This field presented the greatest challenge for law enforcement in cases where there was no license. There is no way for an officer to fill in information for an unlicensed driver. As a result, this field is often left blank. Law enforcement auditors also indicated a need for an ‘out of state’ license option.
