Speed limit signs are ubiquitous on roads across the country.

The national speed limit sign usually appears on roads where a default limit applies, often in rural areas. Minimum speed limits are less common but might be found on specific stretches of road, such as motorways or dual carriageways, to ensure traffic flow. Signs indicating the end of a speed limit zone are vital for knowing when the restriction is lifted.

Clear answers to common questions about the Great Britain Speed Limit Signs road sign category. Use this FAQ to review tricky rules, understand how these signs appear in exam scenarios, and remove confusion that often leads to mistakes in the British driving theory exam in Great Britain.
A maximum speed limit sign, usually a red circle with a number inside, tells you the highest speed you are legally allowed to drive. A minimum speed limit sign, which can look different but often has a blue background with a speed number, indicates the lowest speed you must maintain. Driving slower than the minimum limit can also be an offence, typically if it causes an obstruction.
A speed limit zone begins when you see the sign indicating the new maximum or minimum speed (e.g., a 30 mph zone entry sign or a maximum 40 mph sign). The restriction ends when you see the sign that signifies the end of that specific zone (e.g., an end of 30 mph zone sign, or often the national speed limit applies sign).
The 'National speed limit applies' sign (often a diagonal black and white bar) signifies that the general speed limits for that type of road apply, as opposed to a specific, lower limit set by a zone sign. These national limits are typically 70 mph on motorways, 70 mph on dual carriageways, 60 mph on single carriageways, and 30 mph in built-up areas, unless other signs indicate otherwise.
Signs warning of speed cameras or average speed checks indicate that enforcement is in operation in that area. While not every camera might be active at all times, you should always assume that enforcement is possible and drive within the legal speed limit. Treat these signs as a strong reminder to check your speed and ensure you are compliant.
No, the speed limit is the maximum legal speed. You must always drive at a speed appropriate for the conditions. This includes factors like fog, rain, ice, heavy traffic, poor visibility, and the condition of your vehicle. Driving too fast for the conditions, even if under the legal limit, can be a dangerous driving offence.
