Knoxville Drivers’ Education students spent time with emergency personnel Wednesday morning learning more about their operations. Knoxville Fire Chief Nick Bonstell says they used an SUV to demonstrate how rescue personnel extract people from a car in an emergency situation. He explains it was part of their discussion on how to react if you’re involved in an accident. Bonstell says they also discussed the importance of pulling over for emergency vehicles and giving them an extra lane when possible.
