You can refuse a blood test in Rhode Island under the same implied consent framework that governs breathalyzer refusal. The refusal triggers the same automatic license suspension and civil charge. The difference is that blood tests typically require a warrant under Missouri v. McNeely (2013) unless an exception applies, which gives the defense an additional procedural attack point. Officers sometimes obtain blood draws via warrant even after a refusal, and the warrant process is itself reviewable for sufficiency of probable cause. Rhode Island also uses urine tests in certain drug DUI cases, with similar procedural rules.
