Large Blind Spots ("No Zones")


  • A commercial driver has limited visibility on all four sides because of large blind spots around the front, back, and sides of the vehicle. Other drivers and road users should strive to stay out of these “No Zones”.
  • Limited visibility calls for extra caution in passing and being passed by large trucks and buses.
  • Other vehicles and road users should be particularly careful to stay out of the blind spots when a truck is turning, backing up, or changing lanes.
  • Large commercial vehicles also need a longer following distance so commercial drivers can see the vehicles behind them. If you can’t see the truck driver in his or her side mirrors, the truck driver can’t see you.
