Difficulty: MediumSpeed Control and Following Distance

You are driving on a roadway with a posted speed limit of 35 mph35\text{ mph}. As you approach a designated school zone with active flashing yellow warning lights, the vehicle directly ahead of you begins to slow down. Which speed control and following distance action is required under safe driving practices?

  1. A
    Maintain your speed at 35 mph35\text{ mph} because reduced school zone speed limits only apply when pedestrians are actively stepping onto the roadway.
  2. Slow down immediately to the posted school zone speed limit and increase your following distance behind the lead vehicle.Answer
  3. C
    Reduce your following distance to less than two seconds to encourage the lead vehicle to maintain the standard 35 mph35\text{ mph} limit.
  4. D
    Disregard the flashing yellow lights if driving during mid-afternoon, as school zone speed controls are enforced only during morning arrival hours.

Answer

Slow down immediately to the posted school zone speed limit and increase your following distance behind the lead vehicle.
Slowing down to the active school zone speed limit complies with traffic laws, while expanding following distance behind a decelerating vehicle ensures adequate stopping space if children or hazards suddenly appear.

Step-by-Step Solution

1
Identify active traffic control signals and road conditions.
Recognize that active flashing yellow beacons signal an enforced reduced speed limit in the school zone.
Drivers must obey posted advisory and regulatory speed signals in dedicated safety zones.
2
Adjust speed and establish a safe space cushion.
Decelerate to the lower school zone limit (typically 15 to 25 mph15\text{ to }25\text{ mph}) and extend following distance behind the slowing lead vehicle.
A greater following distance provides extra reaction time if the lead vehicle stops unexpectedly for children or school buses.
