Imagine you’re waiting at a traffic light, watching the signals change. The red light has been holding traffic in place, and suddenly you notice both the red and amber lights illuminated together. Many drivers, especially new ones, wonder: what should you do when you’re approaching traffic lights that have red and amber showing together?
Understanding traffic signal sequences is an essential part of safe driving. While red, amber, and green lights are familiar to most motorists, the combination of red and amber displayed simultaneously can sometimes cause confusion.
In this guide, we’ll explain exactly what red and amber lights together mean, what action drivers should take, why the signal exists, and how to stay safe when approaching an intersection.
What Does Red and Amber Showing Together Mean?
In countries that use this traffic signal sequence, such as the United Kingdom and several other regions, red and amber displayed together indicates that the traffic lights are about to change to green.
Simple Meaning
Red + Amber = Prepare to Go
However, this does not mean you should move immediately.
The purpose of the signal is to alert drivers that the green light is about to appear.
What Should You Do When You’re Approaching Traffic Lights That Have Red and Amber Showing Together?
The correct action is:
Stop and Prepare to Move
If you are already stopped at the traffic lights:
- Remain stationary.
- Prepare to move when the green light appears.
- Check that the intersection is clear.
- Proceed only when the green signal is displayed.
Important Rule
Do not cross the stop line while the red and amber lights are showing together.
You must wait for the green light.
Why Do Traffic Lights Use Red and Amber Together?
Traffic engineers use the red-and-amber combination to improve safety and traffic flow.
Benefits of the Signal
The signal helps drivers:
- Prepare mentally to move.
- Select the appropriate gear.
- Focus attention on the road ahead.
- Reduce delays when the light turns green.
Without this warning phase, drivers might react more slowly when the signal changes.
Red and Amber Is Not the Same as Green
One common mistake is assuming that red and amber together means it’s safe to go.
What the Signal Means
- Red = Stop
- Red + Amber = Prepare
- Green = Go if safe
- Amber = Stop if it is safe to do so
- Red = Stop
Notice that red and amber is a transition phase, not a permission to proceed.
What If You’re Still Approaching the Lights?
The answer depends on your position relative to the intersection.
If You Have Not Reached the Stop Line
Continue preparing to stop unless the light turns green before you reach it.
Drivers should:
- Maintain awareness.
- Control speed appropriately.
- Be prepared for signal changes.
If You’re Already Waiting
Simply remain stopped and get ready to move when green appears.
Common Driver Mistakes at Red and Amber Lights
Understanding common mistakes can help improve safety.
Mistake #1: Moving Too Early
Some drivers begin rolling forward before the green light appears.
This is incorrect and may violate traffic laws.
Mistake #2: Assuming Cross Traffic Has Stopped
Even after the light changes, intersections can remain hazardous.
Always check for:
- Late vehicles
- Cyclists
- Pedestrians
- Emergency vehicles
Mistake #3: Distraction
Drivers often look at phones, adjust controls, or lose focus while waiting.
The red-and-amber phase is designed to refocus attention on driving.

Even when the light is about to turn green, rushing can be dangerous.
Potential Risks
- Cross traffic still clearing the intersection
- Pedestrians finishing a crossing
