A strong theory response is to slow progressively, keep good spacing, and avoid treating the posted value as a target. It is listed in the catalogue as code national-speed-limits.

No, the national speed limit is the maximum you can legally travel under ideal conditions. You must always adjust your speed to match the prevailing conditions, such as poor weather, heavy traffic, limited visibility, or a poor road surface. Your speed should be safe and allow you to stop well within the distance you can see to be clear.
A common trap is assuming the national speed limit is always a safe speed. In reality, you must drive below it if conditions demand. Another trap is not knowing the specific national speed limits for different road types (e.g., single vs. dual carriageway, built-up areas) which are important for theory test questions. Always consider the vehicle class too, as limits can differ.
Repeater signs are used to remind drivers of the speed limit, especially if there has been a break in a speed zone or a change in the limit. If you see a repeater sign for national speed limits, it reinforces the default maximum speed for that road type. You must still adhere to the principle of driving at a safe speed for the conditions, which might be lower than the posted limit.
