How this question shows up on the District of Columbia permit test
Questions in the speed limits category are common on the District of Columbia learner permit exam. The exam tests your knowledge of the District of Columbia 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.
