Drug arrests along Interstate 90 in South Dakota often begin as ordinary traffic stops. Knowing why this happens and what the officers can do allows you to prepare yourself for any scenario.
Factors that elevate suspicion
Beyond the reason for the stop, officers may notice other details that raise concerns about possible drug activity:
- Driving patterns such as abrupt braking or traveling well below the speed limit
- Details about the vehicle, including strong air fresheners or signs of hidden compartments
- Travel plans involving a rental agreement in another person’s name
- Behavior during the stop, such as giving answers that conflict with a passenger’s account
The significance of these details depends on the circumstances in which officers observe them. Taken together, they can affect whether police have grounds for further investigation.
Scope of officer authority during the stop
In a lawful traffic stop, an officer may ask you and your passengers about travel plans, request identification and order everyone out of the vehicle. Courts generally treat these actions as part of the officer’s authority during the encounter. Police may also request consent to search, which you can refuse.
Law enforcement may use a drug-detection dog to walk around the exterior of your vehicle. If the dog alerts to drugs or an officer observes contraband in plain view, those circumstances may establish probable cause. The automobile exception can then permit a warrantless search of the vehicle, including containers found inside it.
Limitations on searches
Police authority during a traffic stop is limited to what is reasonably necessary to address the violation. Officers generally cannot hold you solely to wait for a drug-detection dog unless reasonable suspicion supports the delay.
That suspicion must rest on specific facts the officer can explain rather than a general hunch about nervous behavior. The traffic violation also does not, by itself, permit a search of the trunk or closed containers without consent, probable cause or another recognized exception.
Avenues for defense following an arrest
If the officer arrests you after the stop, you do not have to answer questions about the alleged offense before speaking with a lawyer. This is important because what you say during questioning can later become part of the case against you.
Defense counsel can review whether the officer had a lawful basis for the stop and whether the stop lasted longer than the law permits. Counsel can also examine whether valid consent, probable cause or another legal exception justified the search.
