Answers
Answer:
Red means stop. Wait behind the stop line.
Do not go through the intersection.
Traffic light showing yellow lightYellow (amber) means stop. You can enter the intersection if you are so close that sudden braking might cause a crash.
Traffic light showing green lightGreen means proceed through the intersection carefully.
Step-by-step explanation:
Some traffic lights have arrows to control traffic turning right or left.
A green arrow means you can only turn in that direction.
A red arrow means traffic waiting to turn must wait behind the stop line until the arrow turns green or disappears, even if there is no traffic on the road.
Traffic light showing red light with green right arrow lightYou must not go straight ahead or turn left. You may turn right.
Traffic light showing red light with red right arrow light You must not turn right but you can go straight ahead or turn left if the way is clear.
Traffic light showing red light with flashing amber right arrow light When the yellow (amber) arrow is flashing, you may proceed but you must give way to any pedestrian who is crossing the road into which you are turning.
