Difficulty: MediumTraffic Lights and Signals

Match each traffic light signal to the specific action and legal rule required of the driver.

  • Steady amber light showing alone at a road junctionStop at the stop line unless you are so close that pulling up abruptly could cause a collision
  • Red light showing together with an amber light at a road junctionWait behind the stop line and prepare to go, but do not pass the line until green appears
  • Flashing amber light at a pelican crossingGive way to pedestrians already on the crossing, but proceed if the crossing is completely clear
  • Twin alternating flashing red lights at a level crossing or fire stationStop behind the stop line and remain stationary until the signal ceases flashing

Answer

Steady amber matches stopping unless unsafe to do so; red and amber together matches waiting behind the line until green illuminates; flashing amber at a pelican crossing matches giving way to pedestrians but proceeding if clear; twin alternating flashing red lights matches stopping completely until the signal ceases.
According to the Highway Code, a steady amber light alone instructs drivers to stop before the line unless stopping abruptly could cause a collision. Red and amber showing together instructs drivers to wait behind the line until green appears. Flashing amber at a pelican crossing allows drivers to proceed if the crossing is clear, while requiring them to give way to pedestrians still crossing. Twin alternating flashing red lights create an absolute mandatory stop until the signal ceases.

Step-by-Step Solution

1
Identify the standard sequence and rules for steady amber and red-with-amber at road junctions.
Steady amber mandates stopping unless unsafe, while red and amber combined requires waiting behind the stop line until green shows.
Under the Highway Code, amber alone conveys a requirement to stop if safe, whereas red-and-amber warns that green is imminent but does not permit crossing the stop line.
2
Distinguish the unique rules for pedestrian pelican crossings and emergency/level crossing signals.
Pelican flashing amber allows proceeding only if the crossing is clear of pedestrians, whereas twin alternating red lights demand an unconditional stop until turned off.
Pelican crossings feature a flashing amber phase to minimise traffic delay once pedestrians finish crossing, while twin alternating red signals protect severe hazards such as train crossings and emergency vehicle egress.
