A common mistake is treating the main temporary sign and the KM1 plate as separate messages. Learners might also fail to prepare in advance, assuming the hazard starts only when they see the main sign, not considering the distance indicated by the KM1 plate. It's crucial to understand that the KM1 plate modifies the immediate relevance of the primary sign.
Not necessarily. The KM1 plate specifies the distance or extent of the temporary condition.
