Final answer:
The correct statements about speed limits in North Carolina are: I. The speed limit outside a city is 55 mph unless otherwise posted, and II. The speed limit inside a city is 25 mph unless otherwise posted.
Step-by-step explanation:
The correct statement about speed limits for cars in North Carolina are:
- I. The speed limit outside a city is 55 mph unless otherwise posted. This means that if there are no specific speed limit signs, the default speed limit is 55 mph.
- II. The speed limit inside a city is 25 mph unless otherwise posted. Similarly, if there are no signs indicating a different speed limit, the default speed limit inside a city is 25 mph.
Therefore, both statements I and II are correct.
