If another driver becomes angry with you, that driver can easily call the police and report you as a drunk driver. The driver doesn’t have to give a statement to the police. In fact, the allegation can be completely anonymous.
Should police officers be permitted to stop you based only on another person’s anonymous tip? That question will be answered by the Ohio Supreme Court, as it recently agreed to hear the case of State v. Tidwell. The case could have broad implications, not for not just OVI cases, but for individuals’ Fourth Amendment protections in general.
