The maximum limit should be driven only in ideal driving conditions, and you must reduce your speed when conditions require it.
At a stop sign you must stop behind the stop line or crosswalk, if one is present, or before the sign itself.
Stopping in the crosswalk blocks people on foot and puts your hood in the path of cross traffic.
You must stop behind the stop line or crosswalk, if one is present, or before the stop sign itself.
A yield sign means you must slow down and yield the right-of-way to traffic in the intersection or roadway you are entering.
Pulling out at this sign without slowing lets a car on the main road hit you broadside.
It means you must slow down and yield the right-of-way to traffic in the intersection you are crossing or the roadway you are entering.

How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
