Mississippi DPS Practice Test 2025

Miss. Code Ann. § 63-33-1 bans texting and posting to social media while driving in Mississippi. The fine is $100 (effective July 1, 2025). Importantly, Mississippi does NOT ban handheld phone calls — a driver may legally hold their phone and talk while driving. Only texting and social media use are prohibited. Hands-free options (Bluetooth, speakerphone not held in hand, voice-to-text) are encouraged but not legally required. The ban applies to all drivers with no age exception. This is directly tested on the Mississippi DPS knowledge exam — know the scope: texting and social media = banned; handheld calls = not banned.

Yes — Mississippi requires ALL occupants in ALL seats to wear seatbelts. Mississippi's seatbelt law covers the driver, all front-seat passengers, and all rear-seat passengers. It is a primary enforcement law, meaning a DPS officer can stop you solely for a seatbelt violation. Children under 4 must be in a car seat; children ages 4–6 who are under 4'9" tall or under 65 pounds must use a booster seat; children under 13 should ride in the backseat for air bag safety. This full-coverage seat belt requirement is a common exam topic.

Mississippi uses DUI (Driving Under the Influence) terminology. For adults 21 and older, the legal BAC limit is 0.08%. For drivers under 21, the threshold is 0.02% — effectively a near-zero-tolerance standard. First-offense adult DUI penalties include fines of $250 to $1,000, potential imprisonment up to 48 hours, and license suspension up to 90 days. Mississippi also requires completion of the Alcohol Safety Education Program (MASEP) as a condition of reinstatement. Repeat DUI offenses carry progressively harsher penalties including mandatory ignition interlock device installation.

Mississippi summers routinely bring ambient temperatures above 100°F and high humidity, with road surface temperatures reaching 150°F. To protect vehicles and avoid dangerous situations: check tire pressure in the morning before driving (heat increases pressure during the drive and underinflated tires are more susceptible to blowouts), inspect tires for cracks or wear that heat can worsen, maintain proper coolant levels and check the radiator cap and hoses before long trips, keep the gas tank at least half full (fuel evaporates faster in heat and a full tank prevents fuel pump damage), and avoid parking on soft asphalt for extended periods, as extreme heat can cause tire deformation.

The Natchez-Vidalia Ferry is one of the last operating toll-free vehicle ferries crossing the Mississippi River, connecting Natchez, Mississippi with Vidalia, Louisiana. It provides an alternative to the Natchez-Vidalia Bridge (US-84) for shorter local trips. When boarding, drivers must follow crew instructions for vehicle placement on the ferry deck, set the parking brake, turn off the engine to reduce fumes and fire risk, and remain in or near the vehicle (or in designated passenger areas) during the crossing. Ferry boarding protocols are sometimes tested on the Mississippi DPS knowledge exam as an example of specialized vehicle operation rules.

Mississippi's driver licensing is administered by the Department of Public Safety (MDPS), Driver Service Bureau. Mississippi does not have a department called the 'DMV' — instead, DPS handles both law enforcement (Highway Patrol) and driver licensing functions under one agency umbrella, similar to how Oklahoma and Tennessee organize driver services. The Driver Service Bureau (driverservicebureau.dps.ms.gov) processes applications for learner's permits, driver's licenses, CDLs, motorcycle endorsements, and ID cards. The knowledge exam consists of 30 questions with an 80% passing threshold (24 correct).

Mississippi is highly prone to flooding, particularly in the Mississippi Delta region (which lies below the floodplain of the Mississippi River and its tributaries) and along the Gulf Coast (which is subject to storm surge and tropical rainfall during hurricane season, June through November). Roads in the Delta frequently flood rapidly after heavy rainfall, and the depth of water on a road is impossible to determine visually. As little as 12 inches of moving water can sweep a passenger car off a roadway, and 2 feet can carry away most trucks and SUVs. Mississippi drivers must obey all 'Road Closed' barriers at flooded crossings and must never attempt to drive through water of unknown depth — this is the basis of the 'Turn Around, Don't Drown' safety message.

Mississippi residents may apply for a learner's permit at age 15 after passing the DPS written knowledge exam and vision test. Permit holders must be accompanied at all times by a licensed supervisor who is at least 21 years old and seated in the front passenger seat. Mississippi's graduated driver license (GDL) system requires permit holders to maintain the permit for a specified period and log supervised driving hours before advancing to a restricted license. The restricted license stage includes nighttime driving restrictions and limitations on the number of non-family passengers. Full license eligibility depends on age, time held in the GDL stages, and a clean driving record.

The Mississippi DPS knowledge exam tests standard national sign shapes and colors as well as Mississippi-specific situations. Yellow diamond warning signs commonly tested in Mississippi include flood warning signs, wildlife crossing signs (white-tailed deer are common throughout the state), and construction zone signs on I-20, I-55, and US-49 corridors. Green guide signs for the interstate system are tested for understanding exit numbering, interchange types, and milepost systems. Mississippi also uses brown recreational area signs for the Natchez Trace Parkway — a federally operated scenic road with its own speed limit and passing rules distinct from state highways.

Mississippi law doubles all traffic fines for moving violations committed in active highway construction zones. This means if the standard fine for speeding at a certain speed over the limit is $200, it becomes $400 in a construction zone. The doubled penalty applies whether or not workers are physically present in the zone at the time of the violation — the construction zone designation is determined by the posted signs, not by worker presence. Construction zones are common on major Mississippi highways undergoing MDOT improvement projects, particularly on I-20 (Jackson corridor), I-55 (north-south corridor), and US-49 (Delta to Gulf Coast route).
