Your navigation app points to an opening marked by this sign facing you. How should you treat that entrance?
Correct answer: Do not enter the road from this direction.
DO NOT ENTER prohibits entry from the direction facing the sign. A navigation instruction, a nearby destination, or an apparently empty roadway does not change the sign's message.

An entrance roadway joins your road beyond this sign. What layout is being announced at the joining point?

Before a curve, you pass a yellow sign bearing this symbol. What information does it provide?

On a wooded road, this sign appears without a distance plaque. What road alignment should you anticipate?
