A flashing amber light means approach the lock at a safe speed and under full control.
The red flashing traffic light means that you are to come to a stop, yield to other traffic and then you can procede when the way is clear.
Traffic approaching the light is to stop. If the way is clear, traffic can then proceed through the intersection.
A red light - steady or flashing - means STOP. A steady amber light means Caution - signal about to change. A flashing amber light means SLOW DOWN.
A stale green light means that the green traffic light cycle has almost ended and will change to yellow at any moment. One way to tell if it is a stale green is to look at the pedestrian crossing light, if it is flashing do not walk or is solid do not walk it could be a stale green.
A traffic light you seen change to green
stop and proceed when clear, with caution (of course)
means nothing Wrong! It means caution. Something requires extra attention. At an intersection, a flashing circular yellow means to take extra caution, and watch for traffic on the cross road (which has a flashing red light). A flashing red light is the same as a stop sign. A flashing yellow arrow means you ma turn in the direction of the arrow, but you must yield to conflicting traffic. If the flashing yellow light is not at an intersection, it either calls attention to a road hazard on an accompanying sign, or indicates that a special regulation indicated on the sign is in effect (School speed limit 20 when flashing).
Green
a red traffic light means stop and a red blinking flashing light means its a stop sign
In the U.S.A it means you have the right of way but proceed with caution.
A delayed green light means the opposing traffic gets a early green light. Your light will still be red. You have to wait.
