Ch. 7 · Expressway

When entering the main lane of an expressway, if there is an acceleration lane, you must use the acceleration lane to accelerate sufficiently.

[True / False · Easy]

Answer: ✓ True

Explanation

Rules of the Road Chapter 7, Section 2, 1(1) clearly states, "When entering the main lane, if there is an acceleration lane, you must use the acceleration lane to accelerate sufficiently." This is a necessary measure to safely merge into the flow of traffic on the main lane.

If traffic looks clear, can I just merge right away to save time?

Yui

Nope—the statement is true. You must use the acceleration lane to speed up sufficiently before merging into the main lane.

Hikari

So it's not optional, even if there's space?

Yui

Exactly! Matching the flow of traffic keeps everyone safe. Merging too slowly causes dangerous speed gaps.
