Heavy rain makes a road unsafe at its posted maximum. What does the national rule require?
Maintain the posted maximum unless Police direct otherwise
Slow below the posted maximum until the speed is safe✓پاسخ درست
Stop in the traffic lane until the rain ends
Increase speed to spend less time in the rain
توضیح
A posted limit is only the legal maximum for conditions in which that speed is safe. Continuing at the maximum because the sign permits it ignores the separate duty to adjust for rain, visibility, traffic, road, and vehicle conditions.
