A traffic light you seen change to green
There is no specific length of time for a red light. Traffic engineers make that determination according to the flow of traffic.
It did change the wrold alot because we didnt have traffic lights and there would be alot of accidents and when they invented the traffic light they could get around easier and it made it safer
"Under a traffic light" implies that it is at an intersection. You are not allowed to change lanes while passing trhough an intersection, you must maintain the lane you are travelling in.
There is no exact time simply because no 2 intersections are the same, there are factors that change this time such as: How much traffic goes through the intersection on one direction?
