Maybe a certain permit that would allow them to be on the 400 series during those times if it was a rush delivery or something.
sounds like you're proposing another Government cash grab!
wouldn't it be something if a single lane of each 400 series highway was dedicated as a truck lane.
the logistics might be something to work on but i'm sure something like that could work.
single file, no passing, dedicated lane.
That would not work for some obvious ( to me ) reasons.
With single file and no passing there would be a nose to tail, like 15 feet apart, convoy miles long moving at the speed of the slowest. You see the convoying happen anyway on the 401 but fortunately only a few trucks at a time.
If it were the right lane then how would a car exit. Would YOU try to squeeze into one of those gaps in the dark or in bad weather to exit...even if you could even see the exit sign. I wouldn't.
If it were the left lane then the other lanes would be full of trucks trying to enter or leave that lane on every exit/entrance and for the exiting trucks they would be moving right, their 'blind side' across two or three lanes of faster car traffic.
