Class I two-lane highways are typically associated with which arterial type and speed?

• A. Minor Arterials (lower speeds)
• B. Major Arterials (higher speeds)
• C. Freeways
• D. Local Streets

Answer: (B)

Two-lane highways classified as Class I are designed to move traffic efficiently over longer distances between places, prioritizing mobility and higher speed rather than local access. This aligns with major arterials, which are built to carry higher volumes at higher speeds compared with local streets or minor arterials. They usually have fewer at-grade intersections and driveways, improving flow, but they aren’t full freeways because they’re typically not fully access-controlled or multi-lane. Local streets focus on access to adjacent properties with slower speeds, so they don’t fit. The two-lane, high-mobility characteristic of Class I fits best with major arterials and their higher-speed operation.
