How do I impose a "light traffic ban"?

I have a region in my city with residential on the left and industrial on the right:
The residential area imposes a Heavy Traffic Ban policy to keep those vehicles from clogging the roads. I would like the freeway on the right to impose a "Light Traffic Ban", making this pair of freeways serve mutually exclusive types of vehicles.
Can this be done?
Best Answer
It looks like there is no way to do this in the standard game. Additionally, it would appear that, as of two months ago, this is an outstanding request for a mod on the CS Modding Reddit. So the best answer would be 'not yet.'
That said... in my experience, light traffic tends not to hold up lanes when stopping, is typically A-B, and is relatively quiet and clean compared to heavy traffic.
With careful road design, you shouldn't need to exclude light traffic from areas with industrial and commercial connections - partly as it's more likely to take alternate routes, and partly as it's less of a concern for overall traffic anyway.

The approach has been called the traffic light approach to feedback because it focuses on three levels of feedback: red (stop), yellow (caution), and green (continue). Red Light. When you begin giving feedback to someone, you should begin with the red light- or the thing that needs to stop or be corrected.How do you make a red light turn green?
Flashing RED traffic light (stop signal) means the same as a stop sign. You must come to a full stop and then you may go when it is safe to do so. Flashing YELLOW traffic light (caution signal) means slow down, check for cross traffic and proceed with caution through the intersection.\u200bHow Can I Make A Traffic Light Turn Green?
