Why wont my breaks relese

I don't know what to say if this is a real post...

 

If they only remove the blue line your trailer brakes wont work and you wont know it until you try and use them. This is why you should always do a tug test with the hand valve after leaving your truck.

 

I just look before I get back in.

 

I've heard of people putting a quarter in between the hands on the blue line. You wont see it without removing, or doing a tug.

 

It is the red line. It is the same as trying to pull with brakes set. Blue line is your service brake meaning with a quarter there you won't have trailer brakes.

 

This, a guy at work did this once (I know who it was, got himself fired not long after) and it's sooo not cool. Anytime I come back to my truck I check, every single time. PITA, but the one time it happens....
