The field Driver Trapped was completed in an acceptable manner in nearly 95 percent of the reports reviewed, with each of the three submission types deemed acceptable at least 90 percent of the time. The biggest issue was with paper submissions from local police, as those reports had an empty Driver Trapped field about 9 percent of the time. Similar to the Driver Ejected field, auditors indicated that often times, if the driver was not trapped, officers left this field empty. The Passenger Trapped field was found to be acceptably complete in 90 percent of reports reviewed. State Police had the highest percentage of reports deemed unacceptable, with 25 percent of reports reviewed having an empty field. This was true for most passenger fields in this section of the crash report. Auditors indicated that if there were no passenger injuries, this section was often left incomplete.
