Difficulty: MediumTraffic Lights and Signals

A driver is approaching a pelican crossing displaying a steady green light when a pedestrian activates the push-button unit. Place the subsequent traffic light signals in the exact order in which they will appear to the driver until normal traffic flow resumes.

  1. 1Steady amber light illuminates
  2. 2Steady red light illuminates
  3. 3Flashing amber light illuminates
  4. 4Steady green light illuminates

Answer

The correct sequence of signals at a pelican crossing after activation is: Steady amber light illuminates, followed by Steady red light illuminates, followed by Flashing amber light illuminates, and concluding with Steady green light illuminates.
At a pelican crossing, once the pedestrian button is pressed, the signal changes from steady green to steady amber (advising drivers to stop unless unsafe), then to steady red (mandatory stop while pedestrians cross). Following red, pelican crossings display a unique flashing amber light (giving way to pedestrians still crossing, or proceeding if clear) before returning to a steady green light.

Step-by-Step Solution

1
Identify the signal displayed immediately following green upon crossing activation.
Steady amber light illuminates.
According to the UK Highway Code, a steady amber light warns approaching drivers to stop unless they are so close to the stop line that pulling up might cause a collision.
2
Determine the phase that follows the steady amber warning.
Steady red light illuminates.
Steady red creates a mandatory stop for all vehicular traffic so pedestrians can begin crossing safely with a green walking figure.
3
Identify the unique transitional signal used exclusively at pelican crossings after red.
Flashing amber light illuminates.
Pelican crossings feature a flashing amber phase after red (unlike standard red-and-amber traffic lights), allowing vehicles to move if the crossing is completely clear.
4
Determine the final phase that restores general progression.
Steady green light illuminates.
Once the crossing cycle concludes, steady green returns, permitting traffic to proceed if the crossing and road ahead are clear.
