How much wind is dangerous?

I don't need to know the wind speed....I can feel when it's too much through my hands on the steering wheel.

As others have mentioned, every situation is differrent. Also,err on the side of caution. I believe that the heavier the rv, the more cross wind you can withstand comfortably. As ex-semi drivers, running light or empty was our greatest fear in wind. An empty 53ft. dry van is lighter than many of our rv's and has more side surface area, making them easy to roll over. If it is a heavily loaded van, it takes a great deal of cross wind to roll it over. We (during our career) were in some pretty bad stuff, but never felt uneasy,as long as we were heavily loaded.

In summary: there is no definitive answer!

That's my general rule of thumb.
Won't take the RV or the motorcycle out if the sustained winds are 40 MPH or over.....partly because the gusts usually are MUCH higher.

Then....when on the road, if I get the feeling more than once that a big truck is about to blow past me......but none is really there.....then it's time to stop.

Surrounding terrain can also be a factor, enhancing damage that winds can do, even at relatively low velocity. The area just south of Cheyenne, WY is frequently subject to strong winds, that are exacerbated by the open terrain and the angle of the interstate in that particular area. Semis are frequently blown over on that stretch, I've seen a dozen or more rigs on their sides at various times in that area.

40mph is getting pretty bad.

And gusts take a toll, too.

I was storm stayed in Grand Forks in March. A wind came along that was so strong it pealed my piano tuning signs off the sides of the RV. They were just fine at 75 mph on the highway. Until then I've never been frightened of the wind. I was parked in the lee of a large snow drift, too.

Depends crosswind, tailwind, headwind different answers for each.

Listen to the above very good advice

Not an absolute...it depends....

15 MPH could be too much...10 MPH could be too much...it depends...even 60 MPH MIGHT BE OKAY...it depends...

How many sq inches to your trailer side ?

How good a sail area is your trailer side profile? Rounded edges much better than squared edges in regards to wind issues...

How fast are you going to be at ?

Sustained wind or gusts ?

Square to your trailer side or oblique ?

Semi's weighing in the 80,000 range has been blown over...I've seen them the next day as I drove by them...asked the patrolman and he said that they were all were STOPPED on the side of the road when they were blown over...

Laws of physics kind of stuff.....that we "ALL" face...regardless whether believe in these laws or not...

It does not matter what "wind speed" - if the conditions feel unsafe to me I get off the road until the conditions improve.

I have been traveling down interstates where I come to a break in the trees and the wind gust nearly blew me off the road.

There is nowhere I could possibly be going, towing an RV, that is worth risking my life or the life of others over.

When it reach's the point where you feel uncomfortable with it pushing you around. Better to be safe then sorry when you unit flips over because of wind.
