Oncoming traffic has extended green sign

Practice question

1. 

   You are waiting to turn left on a solid green light and see this sign. What does it warn?

   • A Oncoming cars may keep a green after yours turns yellow
   • B Oncoming cars must stop when your light turns yellow
   • C Your own green light will last longer than usual at this signal
   • D Left turns are allowed only on a green arrow
   Show answer

   A. Oncoming cars may keep a green after yours turns yellow

   Normally, when your light turns yellow, the oncoming light does too, so you can finish your turn. Here the oncoming traffic keeps its green, so you cannot assume a gap will open. Turn only when there is a safe gap, and never into oncoming cars.
