In my opinion, all the Thomas Saf-T-Liner C2 school buses have a serious blind spot due to the location of the driver's side mirrors. When pulling up to an intersection, or stop sign, the driver has to bend forward and backward to see past the mirror for oncoming traffic. I brought this issue up earlier with the manufacturer representative, and he said they would look into it, but no changes have been made or any retro-fit kits to move mirrors.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.
