Road tripping through Mississippi is an adventure filled with live blues music, historic towns, and scenic drives like the Natchez Trace Parkway. But before you hit the road, it’s important to know the state laws that could affect your journey!


Understanding these rules not only keeps you safe but also ensures your trip goes smoothly - without any unexpected fines or surprises! Here’s a short guide to the most important laws to keep in mind while exploring Mississippi by car.
Mississippi takes seat belts seriously. Everyone in the front seat must buckle up, and kids under thirteen need to ride in the back in an appropriate car seat. Think of seat belts as your first line of defence on winding country roads or busy city streets - it’s both a legal requirement and a simple way to stay safe!
Mississippi speed limits can vary a lot: from 70 mph on interstates to as low as 25 mph in school zones or small towns (rural highways often hover around 55-65 mph). Pay attention to posted signs and adjust your speed for weather and traffic conditions.

Texting or using a handheld phone while driving is a big no-no in Mississippi. Distracted driving is a leading cause of accidents, so if you need to call or navigate, use a hands-free device - or better yet, pull over safely. Staying focused on the road keeps you, your passengers, and other travellers safe.
Mississippi has strict laws against driving under the influence, with a BAC limit of 0.08% for adults. Driving drunk isn’t just illegal - it’s extremely dangerous! According to Pascagoula DUI lawyer Kyle Miller, alcohol slows your reaction time, impairs judgement, and increases the risk of accidents, injuries, and fatalities.
If you’re planning to enjoy Mississippi’s nightlife or try a local brewery, always have a sober driver or rideshare ready. Your safety (and the safety of everyone else on the road) depends on it, it should be your top priority to avoid drunk driving accidents.
If you see flashing lights from a police car, fire truck, or tow truck, slow down and move over when possible!
