can you use the bus lane to overtake the vehicle signalling to turn right?

You can use the bus lane to overtake a vehicle that is signaling to turn right, but this is generally allowed only under specific conditions and often with restrictions on the distance you may drive in the bus lane. For example, in some regions such as Victoria, Australia, drivers are allowed to enter the bus lane to overtake a vehicle that has stopped to turn right, but they must not drive in the bus lane for more than 100 meters and must give way to any vehicle already in the bus lane before moving into it. Also, these rules may vary by jurisdiction and depend on local signage and regulations. In summary, overtaking a right-turn signaling vehicle by temporarily using the bus lane is permitted in some areas but requires caution, adherence to local traffic laws, and often a short distance limit in the bus lane.
