We see posts like this all the time. People simply do not know what they are driving, how to drive it, or even if it is safe to drive.
However, you Canadians best be careful on here when you recommend testing. People south of the border get kind of offended when you imply they should have to take a test, or that any other commercial law should apply to them.
They would rather have people "bleeding air breaks", as long as they themselves do NOT have to do anything special to drive whatever it is they want to without a TEST.
Funny part is....the ones that object the most, would probably pass the test with ease. The ones that couldn't, would benefit from the instructional material.
