Are Truck Speed Limiters In Our Future?

Did a site search and didn't see anything mentioned. I was on "Good Sam's" (an RV site) and noticed this posting/alert. Looks like the ball is rolling downhill for big fast trucks.
From the article. >

The American Trucking Association and Road Safe America have petitioned to establish a safety standard to require Engine Control Module Speed Limiter Devices to be placed on certain heavy trucks. The National Highway Traffic Safety Administration plans to initiate the rulemaking process on this issue with a Notice of Proposed Rulemaking in 2012. Items specific to NHTSA’s rulemaking process include the following:

1. All newly manufactured trucks with a GVWR greater than 26,000 pounds shall be equipped with an electronic control module (ECM) that is capable of limiting the maximum speed of the vehicle.

2. The ECM shall be set at no more than 68 mph by the manufacturer.

3. The ECM should be tamper-resistant, and should be designed in a way that does not allow the speed limiter setting on the ECM to be adjusted to let the vehicle exceed 68 mph.

For more details about this proposed Federal Motor Vehicle Safety Standard, visit Federal Register.

Well that's a bunch of crap. Some states have speed limits higher than the truck can actually go. Sounds like a mess to me. It's better to just go with the flow of traffic than sit there at 55 mph creating a hazard.

I don't think that we'll see that kind of stuff on our trucks, though. 26,000 lbs is way more than any pickup.

All I see this doing is creating a booming market for programmers that can bypass the speed limitation.

That will cause nothing but problems. Its always the driver thats going 55 in a 65 that causes problems. People start swerving around the slow car, and having to slam on brakes

My 2007 is speed limited NOW from the factory.

The ECM defuels at 95MPH, down hill with a tail wind will not go any faster it takes fuel away and the boost drops to zero ( 0 ) !

There is some programmers that remove this but want to keep any foot prints out of my ECM till warranty has run out.

eh your not missing anything, all it does is bounce once it is straight down. Truck will keep pulling, but speedo doesn't go any further.

Thanks for the welcome back Shawn.

This legislature isn't something I'd wish on any of us. I think it's definately along the current administration's lines to do something like that though. Crazier things have happened and are still happening at an alarming rate. Especially with such intellectually superior minds controlling the well-being of this country. Heck, one of them actually saved an island from "tipping over in the sea from overpopulation".

I'm not sure that it was pertaining to just the truck and what it could carry or the truck and what it's capable of hauling.... ie. truck and travel trailer etc. Some references use CGVWR to represent that. Other's not.
