How Slow is Too Slow...

As long as it's above the minimum speed. It's not too slow.

 

Idk but i used to infuriate every super trucker out there when i was running 55-60 going cross country... if someone is going slow i get into it and pass them

 

Your question leaves too many variables to be answered. Weather, terrain, traffic conditions, and what lane they are in. 58-60 is what I ran at as a company driver with a governed truck, but I also stayed out of the passing lanes unless I wanted to step on it.

 

Correct. If the truck is below the minimum speed limit, should have the emergency flashers on.

 

Unfortunately many areas do not have a minimum speed limit.

Goodluck with that, guys don't even do it crawling up a grade anymore at 30 under the limit.

 

If you’re holding me up, you’re going too slow.

p.s. keep your carcass out of the center lane!

 

This can get into a large fresh can-o-worms.
There are minimum speed laws in a lot of states. Some post it, others no. On most interstates it varies between a low of 40 up to 55.

if you choose to operate your vehicle below posted speed limit, keep to the far right lane. Actually that is law. You could be cited.

Weather and other conditions can and will affect things. That’s something everyone should understand.

If a vehicle comes up behind, and moves to pass, hold your lane, hold or even drop your speed for a moment. Do Not Speed Up and match the speed of the passing vehicle. It has nothing to do with courtesy, it’s about safety, it really is safer to just let them by. Even if they are running over the posted limit.

Speaking of safety. A study released back in 2007 by a combination of federal and private agency funding done by Virginia Tech, found that a CMV, operating at 15 mph below the posted limit was 23 times more likely to be involved in a collision. This matched a study done in the 70’s concerning the national 55 mph speed limit. The most famous line from that study.
Speed is the number one cause of collisions.
What they did not do is quote the rest of the story. That it is speed variations that cause the collision.

 

To be fair maybe you're going too fast if you run up on people, and if its going through a town like Chicago or DC, sorry but that second right lane is where i keep it to avoid the merging traffic......

 

There''s no such thing as too slow, unless there isn't a passing lane, in which case anyone slower than me is too slow.
