MISSOURI ≠ THE FEDERAL FLOOR

The rules that are Missouri’s own.

Federal cases set the minimum. Missouri’s courts have their own answers — and those are the ones that control your stop, your search, your report.

MISSOURI SUPREME COURT · 1990

State v. Milliorn

A traffic violation gets you the stop, not a search of the whole vehicle. If your probable cause rests on an odor of contraband, the facts have to actually support smelling it from where you were — a court can disbelieve you.

794 S.W.2d 181READ THE OPINION →

MISSOURI SUPREME COURT · 2005

State v. Pike

An actually observed traffic violation — crossing the fog line onto the shoulder — is a solid, lawful basis for a stop. Anchor the stop to the concrete maneuver you saw, not a vague impression of weaving.

162 S.W.3d 464 (Mo. banc 2005)FULL BRIEF IN THE MO PACK →

MISSOURI SUPREME COURT · 2011

State v. Grayson

A bare, uncorroborated anonymous tip won’t justify a stop — and the second your suspicion is dispelled (wrong person, wrong vehicle, no violation), the detention must end. A prior arrest record is not reasonable suspicion.

336 S.W.3d 138 (Mo. banc 2011)READ THE OPINION →

Each brief cites the decision and the court that issued it. Read the controlling authority and follow your agency’s policy — this is reference guidance, not legal advice. Coverage is not guaranteed and changes with each content release.

FIELD GUIDES — STEP-BY-STEP FLOWCHARTS

FIELD GUIDES · 82 IN THE MO PACK

The call, one decision at a time.

DV, juveniles, hospital holds, use of force, traffic — each guide walks the fork in the road with the Missouri law and procedure built in, the way an FTO would talk you through it.

Reference guidance only — your department’s policy and training take priority.

FROM THE FIELD LIBRARY

Federal cases that reach every Missouri stop.

TRAFFIC STOPS

Pennsylvania v. Mimms (1977)

Ordering the driver out on a lawful stop — what it covers, and what it doesn’t.

READ THE BREAKDOWN →

VEHICLE SEARCHES

Arizona v. Gant (2009)

Once the arrestee is secured, the automatic car search is gone. The two narrow windows that remain.

DIGITAL EVIDENCE

Riley v. California (2014)

Seizing the phone is one question. Searching its data is another.
