Understanding these signals is vital for passing your theory test and navigating junctions safely in Great Britain.
Mastering the standard three-lamp traffic light signal is crucial for safe driving and passing your theory test. This explanation details the correct interpretation of red, amber, and green signals to ensure compliance with Great Britain's traffic rules and avoid penalties.

Get clear, practical answers to the most common questions about the Standard-Aspects - Standard traffic light, with three lamps road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the British driving theory exam in Great Britain.
The main rule is to always obey the signal that is specifically controlling your lane, your intended movement, or your road-user category. This could be a standard red, amber, or green light, or a specific filter arrow.
A green light indicates you may proceed, but only if the way ahead is clear and it is safe to do so. You must not enter a junction if you cannot clear it, even if the light is green. Always check for pedestrians, cyclists, or other vehicles before moving off.
A filter arrow indicates a specific movement (like turning right or left) is permitted, often while other movements might be stopped. You must only follow the filter arrow for the direction you intend to go, and it's still essential to ensure the junction is clear before proceeding.
Common mistakes include assuming green means 'go immediately' without checking if the junction is clear, entering a junction when it's blocked, or not paying attention to filter arrows that may apply to their lane. It's also a mistake to proceed on red or amber unless instructed to do so by a police officer or traffic warden.
Yes, you must be aware of and obey other signals that might apply to you, such as those for trams, cyclists, or buses, or special priority signals. These can operate independently of the main traffic lights and require specific attention.
It means that different signals can be active at the same time for different directions or types of traffic. For example, you might have a green filter arrow for turning right while straight-ahead traffic has a red light. You must only act according to the signal shown for your specific path.
