The F27 Interchange Number Sign is designed to help drivers navigate motorways.

This added information provides extra clarity, reducing confusion about which specific road or direction to take from the interchange.
A common trap is not preparing for the exit early enough. Learners might wait until they see the sign very close to the exit, leading to unsafe lane changes or missed exits.

Always aim to be in the correct lane well before the interchange.
