There are many different No Truck signs...some have No Trucks Except for local delivery,then you are safe as long as you have Delivery receipt...,that would apply to No Thru Truck signs too...It is basically for signs that only say No Trucks.. If you go on your own and dont have permission from a Township official ,ticket will be your responsibility to pay. Pull over, have supervisor call,explain vehicle you are driving and enjoy the 25 minutes of getting paid while all this is taken care of. I am guessing most of the time township will say it need to be on smaller truck...That means new appointment,new delivery date,and very unhappy customer...It is what it is.....those signs are there for a reason,dont understand why our residentials are not done by smaller trucks anyway,...we have plenty of small trucks at our terminal to just do residentials and certain businesses that trailers cant do.
