Difficulty: MediumSpeed Limits and Speed Regulation

Under the Basic Speed Law, a driver may legally maintain the posted maximum speed limit of 55 mph55\text{ mph} while approaching the crest of a steep hill with restricted forward visibility, provided the road surface is dry and no other vehicles are present.

Answer: Answer

Answer

False. The statement is incorrect because the Basic Speed Law requires drivers to adjust and lower their speed for actual conditions, including blind hilltops and reduced sight distance, even on dry pavement.
The Basic Speed Law requires motorists to drive at a speed that is reasonable and prudent for existing road and visibility conditions. Approaching a hill crest restricts line of sight, requiring a driver to slow down below the posted maximum limit to maintain a safe stopping distance in case an obstacle lies just beyond the crest.

Step-by-Step Solution

1
Analyze the relationship between posted speed limits and the Basic Speed Law.
Posted speed limits represent the maximum lawful speed under ideal conditions, whereas the Basic Speed Law governs safe driving speeds under existing conditions.
A posted limit does not guarantee that driving at that speed is safe or lawful when hazards are present.
2
Evaluate the condition of restricted visibility caused by terrain features.
Approaching a hill crest limits the driver's stopping sight distance, creating a hazard that necessitates speed reduction.
Drivers must always travel at a speed that allows them to stop within the clear distance seen ahead.
