How Long Can Police Keep You Pulled Over in Michigan? Understanding Your Rights During a Traffic Stop in Michigan

Being stopped by the police can be stressful, even if you've done nothing wrong. One of the most common questions we hear at Bondy Law, PLLC is:

"Can the police keep me on the side of the road while they investigate something unrelated to why they stopped me?"

The answer: not without legal justification.

In a recent case, our office successfully argued that a Michigan State Police trooper unlawfully prolonged a routine traffic stop after the purpose of the stop had already been completed. Following an evidentiary hearing, the court agreed with every legal argument we presented, suppressed all evidence obtained after the unlawful detention, and dismissed the criminal case with prejudice.

What is the Purpose of a Traffic Stop?

A traffic stop can be initiated by a law enforcement officer who witnesses a driver commit a traffic violation (i.e., speeding, illegal turn, improper lane use, no registered insurance on the vehicle, improper registration, etc.), the officer has probable cause to believe that the driver is engaged in ongoing criminal activity (i.e., drunk driving, possessing drugs, etc.), or the driver is identified as someone who has outstanding warrants for their arrest. A traffic stop is a seizure under the Fourth Amendment. So, not only do police need a lawful basis to initiate a traffic stop, but police also need a lawful basis to detain you longer after the mission of the original traffic stop has been or should have been completed.

If you are stopped for speeding, running a stop sign, or another traffic offense, the officer is generally allowed to:

• Ask for your driver's license, registration, and proof of insurance;

• Verify your identity;

• Ask you questions about where you are traveling to and why;

• Inquire into whether you have been drinking or under the influence of drugs;

• Verify your driver's license, registration, and insurance;

• Check for outstanding warrants;

• Determine whether to issue a warning or citation; and,

• Take reasonable steps to ensure officer safety.

  
  

Once those tasks are completed—or reasonably should have been completed—the legal justification for the stop ends unless something new develops or the officer learns new information that shifts their focus from the initial traffic stop to investigating a potential criminal offense.

Can Police Extend a Traffic Stop?

Yes - but only if the police officer develops reasonable, articulable suspicion that another crime is occurring. That standard is much higher than a hunch or a feeling. The officer must be able to point to specific, objective facts suggesting criminal activity. Courts repeatedly reject attempts to extend traffic stops based on generalized suspicions or innocent behavior alone.

What Doesn't Automatically Create Reasonable Suspicion to Extend a Traffic Stop?

Michigan courts have made clear that many commonly cited reasons do not automatically justify extending a stop. Examples include:

• Nervousness;

• Declining consent to search your vehicle;

• Having a prior criminal record;

• Traveling unusual routes;

• Possessing marijuana in a manner permitted by Michigan law; and,

• Minor inconsistencies in statements that have nothing to do with criminal activity.

  
  

Standing alone—or even combined in many situations—these facts often do not permit police to continue detaining someone after the traffic investigation is complete.

Can You Refuse a Consent Based Vehicle Search?

Absolutely.

If an officer asks: "Do you mind if I search your car?"

You generally have the constitutional right to politely decline.

A simple response such as: "Officer, I do not consent to any searches," is sufficient.

Many people worry that refusing consent makes them look guilty. Legally, it does not.

The exercise of a constitutional right should not be treated as evidence of criminal activity.

Can Police Bring a Drug Dog to the Scene?

Sometimes—but there are important limits. A drug-sniffing dog is not considered part of the normal mission of a traffic stop. Officers cannot delay an otherwise completed traffic stop simply to wait for a K-9 unit unless they already have independent reasonable suspicion of another crime. If waiting for the dog adds time to the stop without lawful justification, the continued detention may violate the Fourth Amendment.

What Should You Do During a Traffic Stop?

Protecting your rights does not require arguing with the officer. Generally stated, arguing with an officer on the road is never a good idea and often results in additional complications in your case.

A few practical guidelines during a traffic stop include:

• Pull over safely;

• Keep your hands visible;

• Provide your license, registration, and proof of insurance when requested;

• Remain calm and respectful;

• Avoid volunteering unnecessary information;

• If asked for consent to search, clearly state that you do not consent; and,

• Never physically interfere with an officer or resist.

  
  

If you believe your rights were violated, address that issue later with an experienced criminal defense attorney—not on the roadside.

What if Police Continue Questioning You After the Traffic Stop Should Have Concluded?

This is where many constitutional violations occur and unfortunately incriminating evidence is obtained by police. Sometimes an officer finishes checking your license, confirms there are no warrants, verifies your insurance, and has everything needed to issue a warning or citation. Instead of ending the stop, however, the officer begins asking repeated questions about drugs, weapons, cash, or requests permission to search the vehicle. Whether that additional detention is lawful depends on what the officer knew before deciding to extend the stop. Courts closely examine the timeline and often review body-worn camera footage to determine whether police had a lawful basis to continue detaining the driver. In our recent case, the court found that the traffic mission had ended before the investigation shifted into a narcotics investigation, resulting in suppression of the evidence and dismissal of the charges.

Every traffic stop is different, but one principle remains consistent:

Police cannot prolong a traffic stop simply because they want to investigate something else.

When officers exceed the constitutional limits of a traffic stop without reasonable suspicion, evidence obtained afterward may be suppressed, and in some cases the charges may be dismissed entirely.
