They should be regulated by law to RH lane only like between BR and Lafayette

Most semis are either governed or have cruises set at a narrow range of top speed for fuel efficiency. The reason one can pass another on a hill is a combination of power difference (HP) and gearing. Some truck run 411 rears which pull hills better than the ones running 396 read ends.

It’s not a lot of sped difference going uphill but enough.

It’s aggravating as hell but that’s why.

If they are passing too slowly it can be considered a "rolling road block" by law enforcement and pulled over/ticketed for it (not sure if it can apply to both trucks or just the one doing the passing). The problem is you rarely see LEOs doing this (or else they don't try passing when LEOs are around).

To add to what others have said about governors, the driver being passed is being a huge doucheball if his speed is within a mile or three within that of the truck passing him and he doesn't slow down a little to help facilitate the passing.

I flew into Philadelphia a few years ago to pick up a car I bought. Drove it back to Alabama. Driving back home thru Virginia, I was pleasantly surprised that they had a law that banned trucks from using the left lane. Lots of traffic, but it moved. When we got back into Alabama, I was quickly reminded that we didn't have this law.

I disagree. If you are passing and only going 2 mph faster than the car you are passing, why are you passing? Do the math and tell me how time you are saving by increasing your speed 2mph.

I see idiots doing this crap all the time. Usually ends up going uphill too! Trucker finally passes the the other truck, and all that he accomplished was to back up other motorist for a few miles, just to swap places with the truck he just passed.

Also, I do believe a ton of motorist think they are in some kind of imaginary race to be first. They slowly pass, then slow down to the same speed, or SLOWER, than the guy they just passed.

Im not a truck driver, but i would assume its hours logged. And that's probably not tracked for independent drivers.



It's all electronic these days, any driver (company, owner operator, or independent) can and will have their logs looked over when they get pulled over. It's just a part of the business now.

Some drivers get bonus's or are just able keep their jobs for staying under a certain MPG. You can tell on some of the software at exactly what RPM's they are shifting and all sorts of other data. Make it easier when you have to fire the guy that refuses to maintain a company standard MPG because they will always blame the truck. Drivers will also get mechanic buddies to bump up their governed speeds which is a pain in the arse to deal with as well

My point was that the truck being passed should slow down so the passing truck can get by faster and thus not be such a traffic hazard.

I see that a lot as well. The ones I see doing it most often are people who aren't coordinated enough to maintain speed (see: cruise control) while talking on their phones (or texting) and people who will be turning off within the next mile or so. Annoying af.

You don't understand tiers/codes of emergencies.
They have specific rules/protocol for level of urgency. If they are driving speed limit with lights but no sirens, they could easily have been transporting a stable patient from a clinic/small hospital to a major hospital.

When you see an amberlamps hauling arse with lights and sirens on, that's a 911 call that warrants rapid response or they're engaged in a rapid patient transport aka life is on the line.
Their responses are regulated and audited for public safety.

ETA: I would know as I have driven amberlampses before. They let me take a non-"code3"(what we called rapid transport) patient to the OLOL, almost tipping over exiting i-10 at Essen Lane. Them things are top heavy.

No, the biggest contributor to traffic on I12 is perpetual construction.

Well then those a holes should do the courtesy to wait till they see not a nair vehicle in sight in their sideview before undertaking the task of slow moses passing someone.

When they do it slowly, and one is kind of caught out there, and they are side by side, they are being dick heads


If im right behind the truck passing slow and they have caused a Pabst Blue Ribbon Line of destiny behind me, when they pass, i hurry up and pass them up and get in front of them in the right lane and slow down 10 mph slower than they are. Then, they are screwed and have to wait for the Pabst Blue Ribbon line of destiny that has piled up in the left lane to pass them. By the time the last vehicle passes and they get back in the left lane, i speed up and my work is done. Frickin aholes.

Yep, out here on I-40 between LR and Ft. Smith, one will try to pass going up the hill and almost get by the other then the one in the right lane will start picking up speed and gaining on the one trying to pass, negating his efforts. It takes forever for them to get it done. Just to add about I-40, I've been on it heading East from Memphis passing traffic in the left lane with people doing the same in front of and behind me. We started up a little bit of a grade and these bastards will just whip their rig out into the passing lane with no regard to the passing traffic causing people to have to slam on their brakes to avoid being hit. Scary

I understand this, but why dont they just slightly adjust their speed downward so that they dont have to pass?

I maintain a range of +/- 3 mph where I don't have to constantly pass people that are going 1 mph slower than me.


This is what I do.

I usually set my cruise control on the speed limit. Most people are going at least five over. When I end up behind somebody going less than the speed limit then I bump it up 5 mph to stay in that 'you won't get a ticket from most cops' zone and then as soon as I pass and have some distance between me and the car that I just passed I get back into the right lane or middle lane if it's a highway with three or more lanes.

Passing a car going <70 by going 75 usually results in a pretty quick pass so that I don't spend too much time in the left lane. This isn't enough for many drivers that are going 80 and 85 miles an hour but frick them because they're breaking the law to a great extent and I'm not going to risk getting a ticket just to appease their inpatient asses that aren't even actually saving much time on their trip. Instead, they would rather me get stuck behind some old lady going 65 or some Mexican going 60.
