  • Can I do the same tight turn in both directions?

    Have a look at this intersection here: https://www.openstreetmap.org/#map=1...6405/-83.91835

    I was going north on Turkey Foot Rd, turning right onto Elsam Fork Rd.

    It's a narrow 1-lane bridge with barriers. When I came in I tought "damn that's tight" but I made it in the first shot without scratching anything. I'm tempted to thank my stubborness more than my driving skills.

    The next day on my way out however I completely failed to get the trailer back onto the bridge. I went off the road nearly as far as I would dare to give myself a larger turn radius, and still it wasn't even close to fitting in there. It was obvious the trailer was going to hit the bridge's barrier. Thankfully I was able to get out in the other direction on Turkey Foot Rd.

    I was always assuming that my rig has the same turning capabilities whether I'm turning left or right. Is it more complicated than that?

    And if you care to share any other suggestions for getting out of tight spots: that would be great. With the kinds of roads I frequently go on: one day I'm going to be stuck next to a tree and wondering what to do next before calling in an army helicopter I recently got an opportuninty to practice my 32-point turns when I ended up in a dead-end parking lot

    Have you ever been in a situation where you had to back up several kilometers/miles because turning simply wasn't an option? I'm sure I'll end up doing that one day.

    You probably got bit by the bridge being the limit when trying to turn south. Making the right onto Elsam Fork could be easier due to the railings of the bridge not limiting your approach. Coming out, the bridge will limit how far you can hold the over turn.

    And Yes some vehicles turn harder in one direction than the other.

      Your tow vehicle and trailer exited the bridge relatively in line. On the return they weren't in line to enter the bridge.

      I understand the 32 point turn. I ended up in a dead end and had to turn around. Long box truck and fifth wheel trailer.

        AndrewSmith, and others who might be interested, here's a link to an explanation of how vehicles turn. Design Vehicles (nacto.org)​. Basically, once the front wheels of the vehicle start to turn, the rear wheels start to turn on a tighter radius, and the trailer wheels start to turn on an even tighter radius. The greater the distance between the front wheels and the trailer wheels, the greater the difference between radii, or off tracking width.

        Depending on how wide we can swing out from the obstruction, and how far we can it our front wheels past an obstruction a turn may be possible to make in one direction, but not the other.
