What must drivers do before backing up a commercial vehicle?

• A. Only check mirrors
• B. Check all mirrors and blind spots, and signal intentions
• C. Back up without checking
• D. Signal and keep looking forward

Answer: (B)

When backing up a commercial vehicle, drivers must prioritize safety by thoroughly checking all mirrors and blind spots, in addition to signaling their intentions. This comprehensive visual assessment ensures that the driver is aware of their surroundings, including any potential obstacles or hazards that may not be visible in the mirrors alone.

By checking all mirrors and blind spots, the driver can identify pedestrians, other vehicles, and any objects that could pose a risk while reversing. Signaling intentions further increases safety by communicating to others on the road that the driver is about to back up, thereby allowing them to take appropriate precautions. This practice is essential in maintaining the safety of the driver and others in the vicinity during the maneuver.
