Absolutely yes. The 810.1 plate has no meaning on its own and must always be read in conjunction with the main sign directly above it. Think of them as a single, combined instruction. Ignoring the plate means you're not getting the complete message, which is a common exam trap.
Never. The main sign might indicate a general rule, but the 810.1 plate specifies exactly where, when, or for whom that rule applies. For example, a speed limit sign might have a plate indicating 'weekdays 7-9 am' or 'for vehicles over 3.5 tonnes'. You must adhere to the more specific instruction provided by the combination.
A frequent mistake is only remembering the main sign's general rule and overlooking the supplementary plate's details. This can lead to incorrect actions, like exceeding a speed limit during restricted hours or on a specific stretch of road. Always treat the main sign and its supplementary plate as one complete traffic instruction for safe driving and exam success.

They are used to make these rules more precise for specific situations, such as a temporary speed reduction near roadworks, a parking ban on certain days, or a no-entry zone only for heavy goods vehicles.
