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

You can use the bus lane to overtake a vehicle signaling to turn right, but only under specific conditions. Usually, this is allowed to keep traffic flowing and avoid congestion, and you must give way to any vehicle already in the bus lane before moving into it. However, this maneuver is typically limited to a maximum distance of 100 meters in the bus lane. Also, you must ensure it is safe and legal in the jurisdiction you are driving in, as bus lane rules vary by location. Generally, you can only use the bus lane for overtaking a right-turning vehicle or avoiding an obstruction briefly, not for general driving in the bus lane.
