I was told to always stop as far away as possible from the exit, and still reach the 'call' button...You gotta get out on your step and reach forward... Twice, I called my old scooler LTL drivers to cry about having to go back to the terminal to work a load that was heavy (13/36/39) or something..and both times they fixed my load by altering my cat scale stopping location
As some drivers said the 80/12/34/34 is a rule that applies to every state (I said 80/20/34/34) you might be legal at 90 depending on the state or province and your license.... one way or another in Canada consider at east 88 as weight ....
