Which option correctly lists the day and night ground slopes?

• A. Day 7°, Night 3°
• B. Day 3°, Night 7°
• C. Day 6°, Night 4°
• D. Day 4°, Night 6°

Answer: (A)

Ground slope limits differ by lighting because visibility and the ability to detect and react to hazards change between day and night. During daytime, operators can tolerate a steeper slope since the risk of misjudging the ground is lower and hazards are easier to spot. At night, visibility is reduced, so the acceptable slope is much smaller to minimize the chance of a slip, tip, or load contact with uneven terrain. This is why the correct pairing is Day 7°, Night 3°. If the ground slope exceeds these limits, you should reposition to flatter ground or level the site (for example, with mats or by grading) before continuing. Use a slope-indicating device to verify the angle. The other options don’t fit because they either swap the day and night values or propose limits that don’t align with the standard day-versus-night safety thresholds.
