You are driving a passenger car at 35 mph on a arterial roadway and approaching an active school zone where a overhead yellow light is flashing next to a sign reading '20 MPH WHEN FLASHING'. A vehicle ahead of you is traveling in the same lane. To properly satisfy speed control laws and maintain safe space buffering, how should you adjust your speed control and following distance?
- AMaintain 35 mph until school children are physically visible on the sidewalk, as reduced school speed limits only apply when pedestrians are actively crossing.
- Ease off the accelerator early to smoothly reach 20 mph by the time you cross the school zone sign, while increasing your following distance behind the lead vehicle.Answer
- CMaintain 35 mph because the Basic Speed Law allows driving at the standard posted maximum whenever pavement conditions are dry and visibility is clear.
- DBrake firmly right at the sign to reach 20 mph instantly, while reducing your following distance to two seconds to keep traffic moving efficiently.
Answer
Gradually reduce speed early to enter the school zone at 20 mph while increasing the following distance behind the lead vehicle.
When approaching an active school zone signified by flashing beacons, a driver must proactively and smoothly slow down to the designated reduced speed limit before crossing the zone boundary. Furthermore, because school zones involve frequent stopping and unexpected pedestrian movements, increasing the following distance behind the vehicle ahead provides a crucial safety margin.
