Ch. 7 · Expressway

Which precaution is correct when exiting from the main lane of an expressway?

[Multiple choice · Medium]

Answer: B: If there is a deceleration lane, check your speedometer while slowing down

Explanation

Rules of the Road Chapter 7, Section 2, 5(2) clearly states, "In this case, if there is a deceleration lane, you must use that lane and reduce your speed while checking your speedometer rather than relying on your sense of speed." After high-speed driving, your sense of speed becomes dulled, so checking the speedometer is important.

Not really! High-speed driving dulls your sense of speed. If there's a deceleration lane, you need to check your speedometer while slowing down.

Wait, so I might think I'm going slower than I actually am?

Exactly. Trust the speedometer, not your gut — that's the safe way to exit.
