how far can you travel in a t3 lane if you need to overtake the vehicle turning right?

You can travel up to 100 meters in a T3 lane if you need to overtake a vehicle that is turning right. This is allowed even if you do not meet the minimum occupancy requirement for the lane, but only for the purpose of overtaking, entering or leaving the road, or avoiding an obstruction. Staying longer than 100 meters without meeting the occupancy rules can result in fines or penalties
