When you exit onto Sierra Hwy off of either Balboa Blvd., or Highway 14, or from anywhere…The speed limit is 50 MPH. It is very difficult to maintain 50 MPH without having your foot on the brakes constantly — especially going downhill. The speed limit should be 60 MPH — that can be maintained very easily. It is strictly for revenue and you are never safe!! The minute you let down your guard, trust me, you will be stopped. Also, the speed limit changes to 45 MPH after you cross Golden Valley Road. This is a fact even people who’ve lived here for years aren’t aware of until they’re finally stopped. So pay attention whenever you travel this road that goes all the way to Palmdale, California (at least 45 miles).
