Police commonly interact with intoxicated suspects; however, little is known regarding intoxicated suspects’ ability to understand and apply their Miranda rights. In the present study, laboratory participants were randomly assigned to alcohol, placebo, or control drinking conditions. Participants’ Miranda comprehension was analyzed using the Miranda Rights Comprehension Instruments (MRCI; Goldstein, Zelle & Grisso, 2014), while controlling for verbal IQ scores. Results revealed that being intoxicated negatively impacted participants’ general understanding of their Miranda rights. However, more research is needed before strong recommendations to law enforcement can be made.
