The Speed Camera sign (879) means a specific speed limit or speed-related rule applies from the point the sign is displayed. It's a reminder that your speed is being monitored or controlled by law.
The primary rule is to adhere to the speed limit shown on the sign, or any other speed restriction it indicates. However, you must always drive at a speed that is safe for the current conditions, which may be lower than the posted limit.
A common trap is assuming the posted speed is always safe. The theory exam tests your understanding that you must reduce speed for poor weather, heavy traffic, poor visibility, or slippery road surfaces, even if it's below the signed limit. Also, know how to recognise when a speed limit zone ends.
Yes, you are not only allowed but often required to drive slower than the posted limit if conditions demand it for safety. Driving unnecessarily slowly without a valid reason, especially in a live lane or on a fast road, can be hazardous and may be an offence.
