STATUTE DETAIL IN THE APP
(NEW JERSEY SHOWN — STATE PACKS RENDER THE SAME)
The rules that are Texas’s own.
Federal cases set the minimum. Texas’s courts have their own answers — and those are the ones that control your stop, your search, your report.
Keehn v. State
A van in the suspect’s own driveway is still a car. Keehn’s minivan held a propane tank whose valve had the blue-green discoloration that means anhydrous ammonia; officers opened the van and seized it without a warrant. The Court of Criminal Appeals upheld the seizure — but ONLY under the automobile exception, and it expressly rejected plain view as the justification. Plain view lets you look. It does not let you in.

State v. Duran
A stop is judged on what you knew and saw at the moment you decided to stop — not on what the video shows later, not on a violation you never noticed, and not on your guess about what the law requires. Duran’s DWI arrest was suppressed because the trial judge found the officer never saw the center-stripe violation the State later leaned on, and the CCA deferred to that finding.

Lerma v. State
‘I pat everybody down’ is not a justification — but it doesn’t sink the frisk either, as long as the objective facts (alone, at night, outnumbered, hands moving where you can’t see, a knife) would make a reasonable officer fear for safety. And the stop isn’t ‘prolonged’ while the mission tasks are still open.

FIELD GUIDES — STEP-BY-STEP FLOWCHARTS
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 Texas law and procedure built in, the way an FTO would talk you through it.
Texas paper plates, decoded.
Paper or metal?
TX temp tags are now METAL (7/1/2025). Paper buyer’s tags are DISCONTINUED.
Run the tag
ALL TX tag types CAN be run through TLETS/NLETS.
8-char alphanumeric?
Dealer temp, out-of-state buyer, buyer provisional, and temp registration plates all use 8-character alphanumeric patterns.
The temp-tag scanner is free for verified law enforcement — with or without a subscription. SEE HOW THE SCANNER WORKS →
Federal cases that reach every Texas stop.
Pennsylvania v. Mimms (1977)
Ordering the driver out on a lawful stop — what it covers, and what it doesn’t.
Arizona v. Gant (2009)
Once the arrestee is secured, the automatic car search is gone. The two narrow windows that remain.
Riley v. California (2014)
Seizing the phone is one question. Searching its data is another.
Cross the line, keep the reference.
Task force, bi-state agency, or a beat near the border — every state gets the same breakdown, and the FEDERAL KIT travels with you.
