In 1971 J. Standard Baker Quoted " Drivers Towing Trailers  Are Four (4) Times As Unsafe As Those In Cars Alone! 

Take Note:

This cause of the accident is the driver of vehicle is "Hitting The Trailer"  

You also must take note that the figures the Government keeps using "Includes" people who hit the front of the tractor...and the rear.

We note they already have "Rear Guards" and they still do not prevent deaths.

We take note that nobody in the Trucking Industry has obtained these figures. 

Not even a massive organization OOIDA has gotten these figures to provide their customer base.

It took us years to get this.
