How this question shows up on the Alaska permit test
Questions in the road signs category are common on the Alaska learner permit exam. The exam tests your knowledge of the Alaska Driver Handbook, and topics like this one show up in multiple forms: sometimes as a direct rule, sometimes as a real-world scenario, and sometimes as a "which of the following is NOT correct" question, which trips up readers who skim. Read every choice carefully and watch for the words "always," "never," and "only."
If you missed this question, do not just memorize the answer — re-read the explanation and try to put the rule in your own words. Study research consistently shows that explaining a rule out loud locks it in much better than rereading the same text.
