Final answer:
When you are in the wrong lane at a busy intersection, continue in that lane to maintain safety. Do not force your way across, stop in traffic, or use arm signals to cut across lanes, as these actions can create hazards.
Step-by-step explanation:
If you are approaching a busy intersection and realize too late that you are in the wrong lane, the safest course of action is to Continue in that lane. Making a sudden lane change can cause confusion and potentially create a dangerous situation for other drivers and pedestrians. Once you have passed through the intersection, you can find a safe place to change directions or get back to the desired route. Remember that forcing your way across could be interpreted as aggressive driving, and stopping in a lane of traffic can cause rear-end collisions or other hazards. Using arm signals is not an appropriate solution if your vehicle is equipped with functioning turn signals, and even then, you should not cut across lanes at the last moment. It's crucial to prioritize safety and follow traffic rules and road markings.
