In most places, "No Trucks" means that commercial trucks are not allowed. Pickups are not prohibited.
However, within the city limits of Chicago and (probably) in some other even pickups are included in the ban. Not an exact quote, but the law refers to all vehicles whose primary design function is to carry cargo.
The bottom line is that on the road that you refer to, pickups are allowed, but to be sure, you will have to check.
