Traffic lights work on a timer, but if you look closely on the road when your stopped at the traffic lights, you should see a rectangle like shape under the car it is called a sensor
And when you drive on it, a signal is sent, so the timer knows a car is waiting, if no other cars are going the other way, the timer will change and the light will go green so you can go.
I hope this answer helps.

How do traffic light sensors work?
Traffic light sensors work by using various detection technologies such as inductive loops, video cameras, or radar sensors to monitor traffic flow at an intersection. These sensors can detect the presence of vehicles waiting at the intersection and communicate this information to the traffic signal controller. The controller then uses this data to optimize the timing of the traffic lights and improve traffic flow.

At the intersection of Main Street and Elm Avenue, how are the stop sign and traffic light coordinated to ensure smooth traffic flow?
At the intersection of Main Street and Elm Avenue, the stop sign and traffic light work together to regulate traffic flow. The stop sign controls traffic on the side street (Elm Avenue), while the traffic light manages traffic on the main street (Main Street). This coordination helps to ensure a smooth flow of traffic and prevent accidents at the intersection.
