CA4: Routine traffic checkpoint complied with 4A

A routine traffic checkpoint complied with the Fourth Amendment where the roadblock was established to check licenses, automobile registrations, and compliance with motor vehicle laws to ensure the safe and legal operation of motor vehicles on the roadways. Defendant did not seriously dispute that the roadblock adequately advanced a significant public interest. Moreover, the checkpoint was not overly intrusive given that it was clearly visible minimally, was operated pursuant to a systematic procedure that strictly limited the discretionary authority of the deputies, and it thus reduced the potential for arbitrary treatment. Finally, deputies did not detain drivers longer than reasonably necessary to accomplish the purpose of checking a license and registration except when other facts came to light creating a reasonable suspicion of criminal activity.
