Question

at an all-way stop, when it comes to right-of-way, \first in, first out\ means ______.
the first road user at an intersection does not have to check for cross traffic
the first road user at an intersection must leave as quickly as possible
yield to the first road user who arrives after you
yield to any road users who arrived before you

Explanation:

To solve this, we analyze each option based on the "first in, first out" right - of - way rule at all - way stops:

1. Option 1: Road users always need to check for cross - traffic for safety, so this is incorrect.
2. Option 2: The "first in, first out" rule is about right - of - way, not about leaving quickly. So this option misinterprets the rule.
3. Option 3: The rule is that the first to arrive has the right - of - way, so you should yield to those who arrived before you, not after. Thus, this option is wrong.
4. Option 4: The "first in, first out" principle means that the road user who arrives first at the intersection has the right - of - way. So, if you arrive later, you must yield to those who arrived before you. This option correctly reflects the rule.

Answer:

D. yield to any road users who arrived before you (assuming the options are labeled A, B, C, D in order. If the original options have different labels, adjust the label accordingly. Here we assume the last option is D as per the order: first option A, second B, third C, fourth D)
