Tractor-trailers on parkways

So this isn't on the topic of technology, but just something that annoys me. I am sitting on the on-ramp to the Saw Mill River Parkway southbound in Mt. Kisco, NY, and what do I see coming up the right-hand lane? A tractor-trailer. Keep in mind, this road explicitly forbids COMMERCIAL VEHICLES ("Passenger cars only" is the rule). So I wait for the truck to pass and merge on to the parkway. A state road service vehicle pulls up next to the truck and motions for the truck driver to follow him and has him pull over at the next exit.

We have several incidents every year where tractor-trailers get on these parkways (many times per their GPS unit) and then end up hitting an overpass that their vehicle was too tall for, and causing all sorts of trouble. One truck a few weeks ago actually hit an overpass, which tore off the top of his trailer, then continued driving 8 miles or so until he jack-knifed going around a curve, destroying the guardrail in the process and closing all lanes of the parkway for several hours.

What I don't understand is why some national news channel doesn't grab these stories and put them out there so that truck drivers around the country can be warned about where they shouldn't be driving. That would be the easiest & fastest way to disseminate this information and hopefully avoid a few accidents. There's other options such as: better signage, better training, placing height bars at on-ramps, etc....but just getting the information out into the public domain would probably help.

Hello, thanks for taking a look at my Blog. I'm sure I'll be posting stuff here regarding technology, probably relating to Lotus Notes/Domino, Windows, web development, and other subjects.
