Parking: There is a Pilot truck stop at the top of the hill north of the Cajon truck scale.
The Cajon scale is located at the bottom of the Cajon grade. This is one of the steep grades with reduced speeds for trucks. At the very top of the hill there is a truck brake check area. Following the brake check, trucks are required to slow down. California bears will sit in the middle sometimes as you go down the grade, so you’ll want to pay attention to that speed limit.
Truckers who take the hill slowly will often find that the weigh station will be closed when they get there- all the trucks passing them filled it up. It’s one of the California weigh stations that closes when the ramp gets full.
There have also been a few truck wrecks in the area- truckers coming down the hill have clipped others that are waiting in line at the weigh station. It’s not a pretty sight.
After clearing the weigh scale, the roadway curves around to the right. Then the roadway splits. To the right is I 15 and to the left is I 215. Truckers in this area need to keep an eye out for cars making last minute lane changes.
The Cajon scale is the only California weigh station that many truckers ever cross. Going in and out of L.A. on cross-country runs from New Jersey, a trucker could route this way every time he came in and out of the L.A. area.
Alternate Route Information
Going to LA take I 40 west to I 15 south to the Roy Rogers exit in Apple Valley for 18 west. I don’t recall it being marked as 18 west but it is the Roy Rogers exit. Turn right going west on 18 and after about 20-25 miles, 18 will end on route 138. Merge to the right on 138 going west toward Palmdale. When you get to the town of Little Rock, start looking for the left hand turn. It will be the first left turn lane you come to and it is at a light. Turn left going up a big hill with several lights on it. Stay in the right lane to get on 14 southbound. 14 South will take you to I 5 south or I 405 south. There is a scale location on 14 but I have never seen it open or heard of it being open.
Customer Feedback:
So as you drive south on 14 there is a short pull-off on the right. This area is used for CHP's portable scales. Living in Palmdale for 25 years and working in LA I have witnessed their use 3 times and that's on the North side.
This scale burnt down recently and is, as of this time, closed down. Posted 09-14-2017
