Zorluk: ZorTraffic Lights and Signals

Match each UK traffic light signal aspect with its precise legal requirement and required driver action under the Highway Code.

  • Red and amber illuminated simultaneously at a standard junction traffic lightMandatory stop behind the stop line; prepare to move off but do not cross the stop line until the green light illuminates.
  • Steady amber light displayed alone immediately following a green signalMandatory stop behind the stop line unless you have already crossed it or are so close that sudden braking could cause a collision.
  • Twin alternating flashing red lights at a level crossing or emergency vehicle exitMandatory stop behind the stop line and remain stationary until the flashing red lights cease, regardless of barrier positions.
  • Green filter arrow illuminated alongside a main circular red lightPermission to proceed only in the specific direction indicated by the arrow, regardless of the red signal for other lanes.

Cevap

Red and amber simultaneously matches mandatory stop while preparing to go; steady amber alone matches stopping unless unsafe to do so; twin flashing red lights match mandatory stop until lights extinguish; green filter arrow with circular red matches proceeding only in the arrow direction.
Each signal aspect under UK traffic law conveys a distinct legal obligation: red and amber means prepare to go but remain stopped; steady amber requires stopping unless doing so risks a collision; twin alternating flashing red lights require an absolute stop until extinguished; and green filter arrows permit movement exclusively along the indicated path.

Adım Adım Çözüm

1
Identify the legal command for red and amber shown together.
Recognise that red and amber signifies the intermediate phase before green, requiring the vehicle to remain behind the stop line until green illuminates.
Highway Code Rule 175 dictates that red and amber means stop and wait.
2
Evaluate the rule for a single steady amber light following green.
Identify that amber requires stopping at the line unless braking would be dangerous or the stop line has already been crossed.
Highway Code Rule 175 allows passing on amber only under strict safety exemption criteria.
3
Differentiate alternating twin red flashing lights from standard junction phases.
Determine that wig-wag signals represent an absolute legal stop until completely deactivated.
Level crossings and lifting bridges use twin flashing red lights to warn of severe immediate hazards.
4
Determine the function of a directional green filter arrow paired with a main red aspect.
Establish that drivers heading in the designated arrow direction may proceed while other movements must wait.
Filter arrows safely segregate traffic flow movements at multi-phase junctions.
