What is the purpose of the KM1 'Distance' supplementary plate?

The KM1 'Distance' plate clarifies temporary warning or information signs. It tells you how far away a hazard is, how long a temporary condition will last, or which lane is affected. It ensures you have adequate time to react to the main sign's message.

How should I react when I see a KM1 plate with another temporary sign?

You must read the KM1 plate and the main temporary sign as a single, complete message. Use the distance information provided to prepare for the upcoming condition, such as adjusting your speed or changing lanes before you reach it. Never ignore the information on the supplementary plate.

What are common mistakes learners make with KM1 plates in the French theory test?

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.

Does the KM1 plate mean the temporary condition starts immediately?

Not necessarily. The KM1 plate specifies the distance or extent of the temporary condition. Unless the main sign or plate explicitly states the condition starts at the sign's location, assume it begins at the distance indicated on the KM1 plate. This is vital for situations like road works or traffic queues.

Are KM1 plates always used with warning signs?

While KM1 plates are frequently used with temporary warning signs (like temporary speed limits or hazard warnings), they can also accompany other temporary information signs. Their core function is always to provide additional detail about the timing, location, or scope of the temporary message conveyed by the primary sign.
