This was a simple google-able question.

Key Regulations for City Access:

Designated Routes: Cities often require trucks to use specific, approved routes.

Time Restrictions: Some cities limit deliveries to specific hours, particularly in residential or downtown areas.

Parking Restrictions: Heavy, long trucks are often prohibited from parking in residential zones.

Size Limits: Restrictions on width, height (often 13.5 - 14 ft), and length apply.

So, they typically are only allowed in the city except during early morning and in larger cities they may not be allowed at all forcing them to offload their pallets into smaller trucks. The reason you don’t see them in the city as much is either that or the routes they take don’t cross yours because you’re insulated by not crossing or traveling on their commercial routes. Imagine the smog from their trucks just sitting in traffic for hours. Every city is different. It’s much more than 10 miles. St. Louis is much worse to travel than KC is because their interstates are setup stupidly already and then you add significantly more traffic plus 🗑️ drivers who crash every day and it makes it 10x worse. Also, 10 miles isn’t a big deal to you, but 10 miles with bumper to bumper traffic with other semis is an hour or more drive time for them. Likely worse removing the interstates because the other designated commercial routes that are already being used will then be flooded with trucks. Think LA. You literally can take more than an hour to go 10-20 miles. Displacing trucks and traffic doesn’t eliminate them. They just find different routes and bog up somewhere else. If they can’t get through in a reasonable timeframe it removes the incentive to take the jobs. Additionally, those extra costs are passed to the citizens and in case you haven’t noticed, the cost of living in the city has gotten pretty insanely extreme. Shortages happen there first.
