Oversize routing

I'd imagine that the lighting requirements in SD are for night travel which is allowed up to 10 wide. Read your permit a little more close and I imagine you'll find that. If running I. The daylight I wouldn't worry about it. You should get a set of battery operated magnet mount FoxFires tho they work awesome for lighting up corners. The routing is something you just get used to try being 15 wide and routed off the interstate onto those same narrow ### roads it can get intense at times.

 

If you are in Iowa why are you running thru South and North Dakota? Washington is west. I would have taken. 90west to 212 in South Dakoto thru Wyoming back to 90 in Montana.
I would have bought an annual permit for both Iowa and South Dakota, they are cheap enough and you can run any route you want, if you check with the state first for construction.
You can wire your amber flashing light into your running lights in rear of trailer. I think you also need one flashing in the front of your truck.
Washington requires you can see to the rear of your load in your mirrors. You should be ok with that little load.
Don't forget your Oversize Load signs front and rear.
There is no rhyme or reason at times for routes the states give. You might be getting routed around a narrow restricted lane for construction that hasn't even started yet.
Good Luck.

 

POE Washington Scale will be open 99.99% sure. Double check and make sure everything is good.
Flags lights and signs, and do you have the required number of snow chains.

 

Haulhand called it. The flashing lights on the extremities is for a night run.

12 goes through the Badlands. Not a bad road. Id wager that wvery one of us that roam both the States and Canada have been through that area.

Theres a StaMart truck stop in Mitchell SD. You can grab some OSOW supplies there (those FireFox lights that @haulhand mentioned). The weather in those parts can be extreme and a night run can help get you out of a bind. StaMarts normally have better food too. A real family restaurant, so please bathe.

In those areas, where the StaMarts and Town Pumps are, its a different scene. You have your locals whocome in there because the food is good, your cattle haulers, grain wagons, oilfield drivers, farmers...everyone goes there. And there's usually a wateringhole. Life is too rugged in those areas to be handholding like the big chain truckstops try to do for the thousands of mega carrier morons.

 

You only need flags on the outer extremity corners of the load. Unless Iowa wants that many flags.
((( I saw one guy flag his truck, front and rear corners of trailer. Rear of load. ( 60 ft. rebar ) ))) I don't know who told him he needed that many flags.

Used to be trucks ran flags on the front bumpers but don't see that much anymore. On the west coast, anyways.

You need amber lights on the front corners, red on the rear corners. For night driving.
Some states might also want amber lights on the truck. Usually on top. Or sides.
Some states won't make you need lights at all up to 10 ft wide. ( CA is one state )

I don't know why you're going through north dakota. You're going to be 90 through SD, using 34/79 up to 90 in MT. With a short corner through wyoming. ( Depending on your pickup city in iowa )

If you have a laptop. Google is your friend. Check load requirements and lights as you get to each state. Very seldom do i get any of that information with my permits. Mostly, all i get is the permit itself. And any road closures listed on the permit. I keep the websights open on the laptop. Just in case i need to print out the extra information sometimes required. As i roll through the states.

 

If there's a loves on your route.

Loves sells the little round beacons. On sale right now for $12.99. Free if you got points,. Batteries will last 60 hours on flash mode. I never use solid mode. They'll all have the red lights. Some will have ambers also. And batteries ARE included.

 

Don't forget to read for speed and lane restrictions also.
Some states keep you at 55. Some states make you use hazards if your climbing a hill and can't maintain faster then 20 mph under the speed limit. And some states confine you to right lane only.

 

Probably someone in you company GPSed and requested the shortest route. 74 to 474 to 74 to 80 has to be the most common OSOW route in the country.

Kudos for reading the permits and doing your homework and trip planning. I don't know how you plan your fuel stop, but I fuel at the beginning of the day. Not after my day has started. You have too little time for that in the winter.
