When to and when not to use 4 wheel drive high

I recommend 4WD use on snow covered roads at low speeds like 35 MPH or under. I have used 4WD at fifty MPH when driving on roads that were completely iced over with ridges frozen everywhere. It ran well. I don’t recommend 4WD use on a highway at 65 MPH, or when there are extensive runs that are only wet. If we knew when we were going to get stuck, we would only use the 4WD then. If conditions are bad on a straight highway, keep it below 55. If conditions are that bad, you should drive slower anyway.
