Question: A dozer operator is pushing material on a busy landfill site. Due to poor visibility from dust and equipment blind spots, what communication protocol should be strictly followed when working with spotters?
Answer options: ✅ Only proceed if you can clearly see the spotter's hand signals at all times.
- Rely on two-way radio communication, assuming the spotter will alert you to hazards.
- Operate based on previous instructions, as conditions rarely change quickly.
- Move slowly and continuously sound the horn to warn others.
Correct answer: Only proceed if you can clearly see the spotter's hand signals at all times.
Explanation: If an operator loses sight of their spotter, or cannot clearly see their hand signals, all machine movement must stop immediately. This avoids potential collisions in areas of limited visibility.
