what is the maximum distance you can drive in the bus lane to overtake the vehicle in front of you

The maximum distance you can drive in a bus lane to overtake the vehicle in front of you (in places that follow Australian-style road rules) is 100 metres.

Key point in plain language

• In jurisdictions that use the Australian Road Rules, ordinary cars may only enter a bus lane to:
  • Enter or leave the road.
  • Avoid an obstruction.
  • Overtake a vehicle that is turning right or making a U‑turn from the centre of the road.

• In those situations, you must not drive in the bus lane for more than 100 m before returning to your normal lane.

Important cautions

• This 100 m limit is a general national rule in Australia, but local signs and state or territory regulations can be stricter, so always follow posted signs first.

• Misusing a bus lane can lead to fines and demerit points , often in the hundreds of dollars in Australian cities.

• Outside Australia (for example in the UK, US, or EU), the rules can be very different: in many places, using a bus lane simply to overtake is not allowed at all unless the lane is outside its operating hours or signs say otherwise.

If you are studying for a test

• If your question matches the wording from common Australian learner or theory resources (“What is the maximum distance you can drive in the bus lane to overtake the vehicle in front of you?”), the test answer is 100 m.

• If your textbook or question bank mentions a specific country (for example “under Australian Road Rules”), assume the 100 m rule unless that resource clearly says otherwise.

Always check your own country’s highway code or driver’s handbook: if local law says you must not use a bus lane to overtake at all, then the correct “maximum distance” there is effectively 0 m except for clearly listed exceptions.

TL;DR: Where Australian-style rules apply, you can drive in the bus lane to overtake the vehicle in front of you for up to 100 metres , then you must move back out of the bus lane.
