Decreasing vehicle understeer was strongly associated with the likelihood of control loss following both the unexpected and expected tire failures. Knowledge of the imminent tread separation reduced the overall probability of control loss from 55% to 20% and had a significant effect on how quickly drivers responded as well as on the nature of their initial responses (i.e., steering orbraking). Driver age was marginally associated with increased likelihood of vehicle control loss, but only on unexpected trials. Vehicle speed at the time of first steering input also contributed to the probability of control loss. Neither the location of the tire that failed (left rear vs. right rear) nor the specific instructions about how best to respond to the tread separation influenced the probability of control loss. Differences associated with vehicle understeer conditions observed in the present study were large and consistent, independent of driver expectations and across driver age groups. It is thus fair to conclude that in the event of a complete rear-tire detread, the increased difficulty in vehicle handling and the associated increased likelihood of loss of vehicle control with decreasing vehicle understeer generalize to real-world driving.

This fact sheet is an outreach tool, designed to assist producers as they attempt to determine whether their operations require coverage under a CAFO National Pollutant Discharge Elimination System (NPEDS) permit. The following common livestock production scenarios and the correlating permitting status for each are designed to assist livestock producers in determining whether an operation requires a permit. A site evaluation by Agency staff may also provide design and operating criteria by which permit problems can be successfully reduced or avoided.
