Practice question

Why is 'sight-side' (driver-side) backing always preferred over 'blind-side' (passenger-side) backing in a commercial truck?

  1. Sight-side backing consumes less diesel fuel
  2. The driver can look directly out the open driver's window and mirror to observe the trailer path and rear pivot, whereas blind-side backing relies entirely on distant passenger mirrors
  3. Tractor transmissions cannot reverse to the right
  4. Blind-side backing is legally prohibited under all circumstances

Answer: B — The driver can look directly out the open driver's window and mirror to observe the trailer path and rear pivot, whereas blind-side backing relies entirely on distant passenger mirrors
