Mine has no idea about the speed limit in the school zone next to my house. Why? Because the speed limit changes based upon if school is in session. When is school in session??? You might be able to tell by looking at the school parking lot. You could open a web browser, navigate to the correct school districts web page, download the school year calendar in pdf form, and determine if today is a school day. Or you could do what my tesla does and lets me drive 10mph over the regular speed limit (as of about a year ago - maybe they’ve fix it)
