Difficulty: MediumSpeed Limits and Speed Regulation

A driver is traveling down a narrow residential street lined with parked vehicles where children are actively playing on the sidewalk. The last posted speed limit sign indicated 30 mph30\text{ mph}. Under the Basic Speed Law, which of the following describes the driver's legal obligation regarding speed?

  1. Reduce speed below 30 mph30\text{ mph} to a rate that is reasonable and prudent for the existing hazardous conditions.Answer
  2. B
    Maintain 30 mph30\text{ mph} because posted speed limit signs establish an absolute legal right to travel at that speed.
  3. C
    Maintain 30 mph30\text{ mph} unless a flashing school zone or playground indicator explicitly mandates a reduced speed limit.
  4. D
    Increase speed slightly to clear the area with children as quickly as possible, provided no other vehicles are approaching.

Answer

Reduce speed below 30 mph30\text{ mph} to a rate that is reasonable and prudent for the existing hazardous conditions.
The Basic Speed Law requires drivers to never operate a vehicle at a speed greater than is reasonable or prudent given weather, visibility, traffic, and roadside hazards. When children are playing near a narrow street lined with parked cars, safety requires slowing down below the posted limit of 30 mph30\text{ mph}.

Step-by-Step Solution

1
Identify the driving environment and hazards present in the scenario.
The environment is a narrow residential street with parked vehicles and children actively playing on the sidewalk.
Recognizing hazards like pedestrians and reduced visibility around parked cars is essential for determining appropriate speed.
2
Apply the Basic Speed Law to the hazard conditions.
The Basic Speed Law mandates driving at a safe speed for existing conditions, which may require traveling significantly below the posted limit.
Posted speed limits apply only under ideal driving conditions.
