You can travel up to a maximum of 100 meters in a T3 lane if you need to overtake a vehicle turning right. This applies even if you do not meet the minimum occupancy requirement for the lane. The 100-meter allowance is specifically for entering or leaving the road, overtaking a vehicle turning right or making a U-turn, or entering a lane from the side of the road. This rule ensures safe and legal use of the lane during such maneuvers.
