I learnt an intriguing statistic this morning: the grade of US interstates cannot be higher than 6%.
Even if there is an hour-long detour, it makes me reconsider travelling off the road in the highlands. I will use a trucker’s atlas to confirm that the route is drivable if there isn’t an interstate within a reasonable distance.
based on interstate standards
Maximum grade: The topography and design speed dictate the maximum allowable vertical angle, or grade, along the roadway, which is typically 6% in mountainous areas, 5% in undulating terrain, and 4% in level land [4]. In cities, an extra 1% is permitted.
These are designed to be enjoyable vehicles to travel in. In my opinion, it doesn’t matter if travelling by train takes an extra hundred miles rather than the rough and tumble route over the mountains. Enjoying the voyage is more important to me than arriving less fatigued, not to mention less damaged equipment.
I passed by this accident about 8pm on Wednesday. When I noticed the front, which was pointing the wrong way and upside down, I was certain it was an RV. Seeing it was heartbreaking. I sincerely apologise for the deceased individual.
I had to pass it again the following day while travelling in their direction. Before you could see it leave the road and descend an incline, there was a lot of black rubber on the road from the front tires. This is how it appeared when it flipped and twirled. It happened at the base of the slope. I’m not convinced the driver had an option except to pull off the road.
I had a rental automobile with me.

Though I can see where you’re coming from, my thoughts are different. I find interstates to be far too busy. Everyone racing against the clock at almost seventy miles per hour. A large highway is more preferable to an interstate. There is less of a concrete washboard effect on the roads, and speeds are lower. I won’t annoy anyone if I travel at 50 or 60 mph.
I have experienced some of those 6% downhill grades in my gasser before. As @Jim said, no
Is this the same road that was partially blocked earlier this year by a landside?
Has anyone happened to read this paragraph?
But as the website Book Outdoors notes, it’s not simple to use the runaway arrestors. The website states, “To use the two runaway truck ramps on an easterly descent, you must cross to the left through head-on, uphill traffic.”
The driver allegedly passed an arresting system half a mile prior to the collision, according to the story. It makes me wonder what kind of stupid civil engineer decided it would be a good idea to have runaways stop and cross in front of incoming vehicles.

That caught my attention as well. Although I haven’t there, the map indicates that the mountain is on the left and the ditch is on the R side, flowing downhill. The highway has two lanes, one up and one down. therefore the explanation. It appears to be a very rough road, made worse by the winter.
One of the difficulties with RVs is that they are often portrayed by the industry as being similar to driving a vehicle or van. Not at all. There were a number of new fans or first-timers at a recent event. It was shocking to see the unit absolutely out of control while following a super C during a test drive. In a terrifying way. The manufacturing representative told me that he had

I have experienced some of those 6% downhill grades in my gasser before. No true engine braking, as mentioned by Jim. I don’t let it get above 50 mph on the long ones, though I’m not sure if that’s the ideal approach. I apply the brakes and reduce the speed to 25 mph when it reaches 50. Let it gradually return to 50 after releasing the brakes, then do it again.
The US Highways are appealing to us.
RV Driving Course. When I went to class A, I completed it. Had I done so prior to the class C. Dealers ought to collaborate with these people, and for beginners, it ought to be included in the rig’s price. Less than half of what it would have cost to fix the damage I caused to the new C on the second petrol fill-up was spent on the two-day course. His list of things to show me was so long that I only had one day. All I needed was some guidance. Yet it was really worthwhile.
