In the context of small roads with lower speed limits, the correct term to describe them is "secondary roads" (Option D). Secondary roads are usually local roads that connect rural areas or serve as alternatives to main highways. These roads typically have lower speed limits and are often used for local traffic and shorter distances compared to major highways or interstates.
Here's a breakdown of the options given:
- A. County roads: While county roads are local roads maintained by the county government, they may vary in size and speed limits. They are not specifically associated with smaller roads with lower speed limits.
- B. Streets: Streets are typically roads within urban or suburban areas, but the term is more general and does not specifically refer to small roads with lower speed limits.
- C. Interstate highways: Interstates are major highways designed for high-speed travel between states or regions. They have higher speed limits and are not considered small roads with lower speed limits.
Therefore, in the context of the question, the most appropriate term is "secondary roads" to describe small roads with lower speed limits.
