Getting pulled over on I-90 is not something any driver wants to happen. And what starts as a simple warning for a speeding ticket can quickly spiral into a worse situation if the officer calls for a K-9 unit to conduct a sniff search.
A K‑9 alert can help give police probable cause to search your car. If they find drugs, you could face a felony charge. It feels like the end of the road, but a K-9’s nose is not the indisputable evidence law enforcement agents want you to think it is.
Watching the clock during the stop
The law strictly limits how long an officer can keep you on the side of the road. Under the U.S. Constitution (and related South Dakota case law), a traffic stop cannot be extended longer than necessary to handle the traffic mission unless they have independent reasonable suspicion. If an officer stalls to wait for a K-9 unit to arrive, they may have violated your rights.
Evidence of stalling may include several specific officer behaviors:
- Taking an unusual amount of time to run a driver’s license or check insurance
- Asking repetitive questions that have nothing to do with the traffic violation
- Waiting for backup to arrive before starting the ticket-writing process
If an officer illegally prolonged a stop, any evidence found during the search might be suppressed by a judge.
When the handler leads the dog
Sometimes a dog’s alert is less about the scent of drugs and more about the handler’s body language. This is known as cueing. This can happen when a dog reacts to the officer’s subconscious signals because the animal wants a reward. Defense teams often review dashcam footage to see if the handler stopped at a specific spot or used a certain tone of voice to trigger the dog’s response.
Investigating the dog’s history
South Dakota courts generally look at a K-9’s training and reliability. If a dog has a high rate of false alerts, its performance can be used to challenge the search. Investigating the dog and handler’s records can reveal if a canine’s nose is actually as accurate as the prosecution claims.
A strong defense for your future
Facing a drug charge based on a K-9 alert is a high-stakes situation. However, the charges are hardly irrefutable. Defense strategies like contesting police procedure during the stop or challenging the K-9’s accuracy could result in dismissal of evidence, and possibly reduced or dropped charges.
