A road grader operator is working on a municipal street reconstruction project. Multiple services (sewer, water, telecommunications) have clearly marked lines at varying depths. How should the operator approach grading near these markings?

Question: A road grader operator is working on a municipal street reconstruction project. Multiple services (sewer, water, telecommunications) have clearly marked lines at varying depths. How should the operator approach grading near these markings?

Answer options:

• Grade cautiously above the general depth of the shallowest service.
• Assume the deepest service is the primary concern and grade accordingly. ✅ Consult site plans, confirm utility depths with the site supervisor, and potentially use hydrovac or hand digging for initial exploration.
• Avoid the marked areas entirely and let utility crews expose their lines.

Correct answer: Consult site plans, confirm utility depths with the site supervisor, and potentially use hydrovac or hand digging for initial exploration.

Explanation: For complex utility crossings, operators must consult specific site plans, confirm depths with supervision, and be prepared for exploratory digging (e.g., hydrovac or hand digging) to prevent striking services.
