What else can I help you with?
What order do traffic lights go from red to red?
Red, red and amber, green, amber, red. It depends where you are. In North America, they go red, green, yellow, red. In at least some places in Europe they go red, amber, green, amber, red.
What colour are signal lights?
Signal lights typically use three main colors: red, yellow (or amber), and green. Red indicates stop or danger, yellow signals caution or preparation to stop, and green means go or that it's safe to proceed. Some variations exist for specific applications, such as blue lights for emergency vehicles or specific traffic contexts.
Where is the green light on a traffic light?
The green light on the traffic light is on the bottom. The yellow is in middle, the red is on top. However, in some municipalities, the traffic lights are not vertical, they are horizontal. In these instances, the green light is usually, but not always, the furthest to the right.
What is a traffic signal that has been green some time?
This is called a "stale green" signal. It is about to change to amber. This is also recognized at some intersections by the flashing crosswalk signal informing pedestrians not to cross.
On a traffic light what position is the green light?
The lowest light on a traffic signal is green. Some cities use traffic lights that are not arranges top to bottom but rather side to side. In this event the green light is usually the furthest to the right.
What does a flashing amber light on traffic lights mean?
A flashing amber light on traffic lights typically indicates that drivers should proceed with caution. It signals that they must be aware of their surroundings and yield to any pedestrians or other vehicles in the intersection. In some jurisdictions, it may also mean that the intersection is uncontrolled, and drivers should treat it like a stop sign. Always check local traffic regulations, as meanings can vary by location.
Are traffic lights controlled?
Some lights have sensors :)

Can a traffic light turn green on both sides?
Typically, traffic lights are designed to prevent conflicting signals; therefore, a traffic light should not turn green for both sides of an intersection simultaneously. In some specific cases, such as at a T-intersection or with dedicated turn signals, lights may be coordinated to allow different movements, but standard traffic lights maintain safety by ensuring that opposing directions do not receive a green light at the same time. However, malfunctions can occasionally cause both sides to show green, leading to dangerous situations.
How long does a traffic light stay green for?
The duration of a green traffic light varies based on factors such as location, traffic volume, and the specific traffic signal system in use. Typically, green lights can last anywhere from 20 to 90 seconds, but some may be shorter or longer depending on the intersection's design and traffic patterns. Traffic engineers adjust these timings to optimize traffic flow and ensure safety for both vehicles and pedestrians.
Why do some traffic lights always seem to turn green as soon as you come to a complete stop at them when they are red?
They have moition sensors that detect movement
Why do you have traffic lights not roundabouts?
Some intersections have traffic lights instead of round abouts because there is too much traffic on some intersections for a roundabout to be safe. Roundabouts have to have a certain amount of traffic to be safe enough for no traffic light.
