Key Takeaways
- A police request leaves you free to cooperate or decline for your own reasons, while a command invokes the officer's authority and creates an obligation to comply.
- Commands are often phrased politely as requests, such as "May I have your license and registration?", while requests like "Can you pop the trunk?" can feel like commands that courts may later treat as voluntary consent.
- You may always ask an officer whether something is a request or a command, though some state courts have allowed the question to count toward suspicion.
"May I look in your trunk?" "License and registration, please." Both sound polite, but one is a request you may refuse and the other is a command you must obey. How are you supposed to tell the difference?
In this TalksOnLaw Brief, Joel Cohen talks with Rachel Harmon, the Harrison Robertson Professor of Law and Director of the Center for Criminal Justice at the University of Virginia School of Law. She explains what separates the two and why the gray zone between them matters.
Requests Versus Commands
A police request, Professor Harmon explains, invites you to cooperate for your own reasons. If an officer searching for a missing person asks to look in your backyard, you might say "feel free"; if he asked you to jump up and down and pat your head, you might say you are busy and go on your way. A command does two things: it tells you what the officer wants, and it invokes his authority, explicitly or implicitly, as a reason to comply. When an officer shouts "Stop, police!" he is not saying he would like you to stop; he is invoking state authority that you are obligated to obey.
Commands Dressed as Requests, and the Reverse
The two are blurred all the time, she says. A traffic stop begins with a silent command: the lights and siren, which create a legal obligation to pull over. When the officer then asks, "May I have your license and registration?" that is a command phrased as a request, because you are required to comply, and the politeness can create ambiguity. The reverse happens too. If an officer has no probable cause to search your trunk, an order to open it would be unlawful, but he might instead ask, "Can you pop the trunk, please?" That may later be argued to be a lawful request, even though you experienced it as a command. She believes this gray zone feeds a sense of alienation in encounters with police.
Asking Which One It Is
You are always permitted to ask whether something is a request or a command, she says, and officers should not perceive the question as confrontational. Yet several state courts have allowed that question to be treated as part of what made a person seem suspicious, which she considers a mistake. Because officers effectively make law when they issue commands, and often enforce them in real time with no chance to deliberate or appeal, she argues that commands need careful governance on the front end. She does not attribute bad intent: officers often face uncertainty about threats and about the scope of their own authority, and she believes legal clarity and better training on commands would help officers too.
What to Know Now
The distinction Professor Harmon draws remains central. Under Schneckloth v. Bustamonte, consent to a search is valid if it is voluntary under the totality of the circumstances, and officers need not tell you that you may refuse, a point the Court reaffirmed in United States v. Drayton. That is why the line matters: a request a court later treats as voluntary can justify a search without probable cause. Some states offer more protection; New Jersey, for example, requires reasonable suspicion before officers may ask a driver for consent to search the car. And under Rodriguez v. United States, officers may not prolong a traffic stop beyond its purpose without reasonable suspicion. If unsure, calmly asking whether you are being ordered or asked, and clearly declining consent to a search, preserves your position for later review.
