What law determines when you have been ordered to pull over for a traffic stop?
<p>What laws in the U.S. (specifically, Massachusetts) govern <em>when</em> you need to pull over for a traffic stop? </p>

<p>I understand that if a police vehicle comes up behind you with lights flashing it's clear that you have to pull over and stop.</p>

<p>But what if a uniformed police officer is standing on the side of the road waving for you to pull over?</p>

<p>What about a uniformed officer police just looking at you? </p>

<p>Obviously evading or disobeying a police officer when he orders you to pull over is illegal.  I'm wondering what constitutes a such an order.</p>

<p>Refusal to submit to a police officer, <a href="https://malegislature.gov/Laws/GeneralLaws/PartI/TitleXIV/Chapter90/Section25" rel="noreferrer">Mass. Gen. Laws Ann. ch. 90, § 25 (2016)</a> governs. The relevant part reads:</p>

<pre><code> Any person who, while operating or in charge of a motor vehicle . . . 
 who shall refuse or neglect to stop when signalled to stop by any
 police officer who is in uniform or who displays his badge
 conspicuously on the outside of his outer coat or garment . . .  shall
 be  punished by a fine of one hundred dollars.
</code></pre>

  (perhaps at a speed trap)</p>
</blockquote>

<p>If the police officer is on a uniform and displays his badge, probably.</p>

<blockquote>
  <p>What about a police just standing on the side of the road, looking at
  you?</p>
</blockquote>

<p>Assuming the police officer doesn't "signal" you to stop, you would be okay under this statute. Whether he is legally justified in asking you to stop is a separate issue outside the scope of you question.</p>

<p><strong>Bottom Line:</strong> Someone who doesn't want to run afoul of this law should stop whenever they think a police officer is pulling them over. </p>
