Thank you! After compiling it, I feel more concern than ever regarding chemical laden trucks (U-Hauls, Ryders, Moving Companies and those typically not inspected at our nation's weigh stations - we are missing a huge potential for nailing terrorists on this one). Also, far too many tanker truck mishaps involving gasoline and hazardous chemicals and road closures. Makes me wonder how these accidents line up statistically with other semi-trailer accidents; ie the number of these accidents in recent months/years compared to 3-4 years ago.
Re- trucks.
I share your concern.
