Motorway number

Purpose and student action

Identify the road regime, destination or service. A change of road regime can change the applicable driving rules.

Read · decide · act

  1. Decide whether the sign identifies a road regime, destination, facility or local name.
  2. If it starts or ends a road regime, apply that regime’s rules, not just the picture.
  3. Plan lane changes early; never cross a prohibited line to recover a missed exit.
