Rhode Island’s drugged driving law is located at General Laws of Rhode Island § 31-27-2. A driver may not operate a vehicle while “under the influence of intoxicating liquor, drugs, toluene, or any controlled substance,” or operates a vehicle, “with a blood presence of any scheduled controlled substance.”
Rhode Island has what is known as a per se (also known as a “zero tolerance”) prohibition against drugged driving if the driver, while driving, has any controlled substance in his or her body. That means that a driver may be arrested if the police officer has a reasonable suspicion that any prohibited drug even if it’s just a trace is in the driver's body while the driver is operating the vehicle. Other than the per se/zero tolerance rule, an arrest can be triggered by a driver impaired by drugs.
Rhode Island’s drugged driving law is directed at the prohibition of “drugs, toluene, or any controlled substance,” or “any scheduled controlled substance as defined within chapter 28 of title 21.” A listing of controlled substances regulated by federal law are found at the Drug Enforcement Administration website.
