Speed limits

In Texas, the maximum speed limit on designated rural interstates can be established up to 80 mph, and even 85 mph on certain toll roads. While 70 or 75 mph are common limits on many highways, they do not represent the absolute maximum daytime speed limit allowed by state law.

In Texas, school zones are typically regulated at 20 mph during active hours to protect children crossing the street. Option D is incorrect because 30 mph is the default speed limit for urban streets, which is too fast for a school zone.
