A 3-minute lesson from the Mississippi course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Alcohol and drugs slow your reflexes and impair your judgment; tests show even two beers can markedly slow your reactions. By driving in Mississippi, you've already agreed to be tested if an officer suspects you're impaired.
Know the rule
Driving under the influence of alcohol or drugs is illegal in Mississippi. The Implied Consent Law sets out the legal consequences.
Marijuana, like alcohol and other drugs including prescription medication, slows reflexes and impairs judgment. Driving under the influence of any drug, including medical cannabis and prescription drugs, can result in arrest.
Smoking medical cannabis in a motor vehicle, or operating or being in actual physical control of a vehicle while under its influence, violates Mississippi law.
By driving in Mississippi you consent to testing for intoxicating substances. An officer with good reason to suspect impairment can request a breath or chemical test of your BAC.
You have the right to refuse the test, but then you must surrender your license to the officer immediately. The officer's receipt serves as your temporary permit, and your license and a sworn report go to the Commissioner of Public Safety.
A 19-year-old driver's BAC registers .03%. That's over the .02% limit for drivers under 21, so the officer will demand the license and issue a receipt that works as a temporary permit for only 30 days.
Check your understanding
