Under what condition may bodily searches like blood tests be conducted without a warrant?

Bodily searches, including blood tests, can be conducted without a warrant under the condition of exigent circumstances. This legal concept refers to urgent situations where law enforcement has a compelling need to act quickly in order to prevent the imminent destruction of evidence or to protect public safety.

For instance, in the context of a blood test, if an officer believes that evidence of intoxication may rapidly dissipate (for example, if a driver was involved in a serious accident), waiting for a warrant could result in the loss of critical evidence necessary for a prosecution. Exigent circumstances justify immediate action by law enforcement, thus allowing them to perform searches or seizures without first obtaining a warrant.

The other conditions mentioned, while they could allow searches in specific contexts, do not universally apply to all situations involving bodily searches. For instance, consent can grant police the authority to conduct a search without a warrant, but that consent must be freely given. Routine traffic stops typically do not allow for such invasive searches unless other factors are present, and mere suspicion of a felony does not automatically establish grounds for a warrantless blood test without exigent circumstances.
