You can travel up to 100 metres in a T3 lane to overtake a vehicle that is turning right, if you don’t meet the usual T3 occupancy requirement (for example, you’re alone in the car).

How this works in practice

When a vehicle ahead of you is signalling and waiting to turn right, you’re allowed to:

  • Move briefly into the T3 transit lane.
  • Overtake the right‑turning vehicle.
  • Return to your original lane as soon as it is safe, and within 100 m of entering the T3 lane.

The intent of the rule is that you only use the T3 lane for the shortest safe distance needed to complete the overtaking manoeuvre, not to continue travelling in it like a normal lane.

Always check your local state or territory road rules, but in Australian guidance and practice questions, the correct multiple‑choice answer for this situation is 100 m.
