    Did you happen be out by Isleton when that happened? Sounds about right for that area, go right end up in the river, go left end up in the slough.

    I pull some 48’ steps with the 24” kin pin setting and the the rear axle/axles(spread and close tandems) all the way to the rear, talking about getting around certain areas……. This is were your professionalism and judgment radius comes to play.

    I got into some interesting places the years I was hauling cattle out there, 280” wheelbase and a 52ft spread. Lol. Somewhere I have an old phone with a pic of my truck coming out on a road with a sign posted vehicles over 35ft not advised.

    If it were all about 53's on certain non-interstate roads, then they should simply put a bridge length limit on specific roads. Think like a politician...'how much fine revenue will we lose if we change the law'. Bottom line, it's all about the Benjamins at this point.

    It has nothing to do with weight, so it has nothing to do with bridge. It’s not any different than any other state that has various restrictions on trailers over 48ft. Florida has a KPRA regulation but will sell a permit if you have fixed axles. Idaho requires a permit for trailers over 48ft if you’re off the national network.

    When I got caught with a 52ft spread the fine was $137.

    Thats exactly it ! Isleton bridge.. one side of the bridge is nice and wide easy turn. Other side is big enough for like a box truck. I was on that side... I attempted the turn even after swinging wide out off the road as far as i could. Didnt make it halfway . Bad part is i knew i wasnt gonna make it and still tried it... Then i had to backup with traffic behind me.. lol going down the road further wasnt exactly graat either... A 8ft wide lane turned into like 6ft wide and then i started trimming tree branches, thats when u know ur really ####ed and completely off a truck road.. luckily there was a boat launch a good distance down the road that was big enough to back up into. Funny enough i could see dual tire tracks there when backing up so atleast i wasnt the first dummy to do something like that .

    A good example of that is coming out of my rebar delivery the other day out in san bern, they had some construction on the on ramp to gdt back on 215 south.. i split the right turn lane and thru lane and then swing wide into left turn lane just to make the on ramp turn and still almost scraped the barriers they had set up... The dry van behind me was able to turn from just the right lane and still had clearance. I was amazed. Even more fun when u get into freight with front overhang. I think that can get u into more trouble than anything. guess thats why they pay us the big bucks
