Final answer:
After passing a vehicle moving in the same direction, it is safe to move back into the right lane.
Step-by-step explanation:
Once you have passed a vehicle moving in the same direction, it is safe to move back into the right lane.
However, it's important to make sure you have enough clearance and you are at a safe distance from the vehicle you just passed before changing lanes.
For example, if you are driving on a three-lane freeway and you pass a vehicle while you are in the middle lane, you can safely move back into the right lane once you have passed the vehicle and there is enough space between you and the vehicle.
