What it means

What does the 100 km/h speed limit sign mean in NSW?

The 100 in a red ring belongs to highways, motorways and country roads, and 100 km/h is also the default outside built-up areas when no sign is posted. Not everyone may use the full number. If you hold a learner licence or a red P1 licence, your ceiling is 90 km/h however high the sign reads. Green P2 drivers may go up to 100, which makes this sign their limit too.

What to do

  1. 1

    On L or red P plates, cruise at 90 or less.

  2. 2

    Keep left and let faster traffic pass rather than speeding up.

  3. 3

    Leave a bigger gap, because stopping from highway speed takes a long way.

The number in the red circle is the most you may drive until another sign changes it. Learner and P1 drivers must still keep to 90 km/h or less.
