If you are overtaking, you must pass on the left at a safe distance and do not _______ until the way is clear from the overtaken vehicle.

When overtaking another vehicle, it is essential to ensure that you pass on the left and maintain a safe distance until you can safely return to your lane. The crucial part of this process is to not return to your original lane until you are certain it is clear and safe to do so. This helps prevent accidents and ensures that you do not cut off the vehicle you are passing.

Returning to the lane too soon can lead to collisions, especially if the overtaken vehicle accelerates or if there are other vehicles nearby that may not be visible in your mirrors. Being patient and only merging back into your lane when it's clear demonstrates safe driving practices and respect for the traffic flow.
