One thing for sure there are a whole lot of Companies selling Auxiliary Braking Systems that Make Claims that There is some legal requirement that requires there being used, but when You question the Various States and Provinces ,No one is willing to back them up!
Do They make sense...Yes ! If they actually work and are installed and set up correctly they just might stop You a bit quicker in a panic situation!We read about performance but are there any real comparison Test Results?
Are they Legally required...Well actually Only if they are Certified as Approved for Use by the DOT! Just like those ... Driving Lights or... those HID Headlight Conversions that are available on E-Bay!
The Scary Part is that the Tow Bars and Hitches that are out there are also, Not DOT approved! And don't get Me started on some of the Idiots that install these devices!
I'm not Ralph Nader but there are a whole bunch of Poorly designed and improperly Installed Hitches,Base Plates and Tow Bars out there!
