Mississippi Has No Motorcycle Lane Statute: The Single-Lane Duty Reaches Only Three-Lane Roads Outside Cities

Start with what is missing, because the absence is the answer. Mississippi has a motorcycle operator's licence requirement at § 63-1-6 and a crash-helmet requirement at § 63-7-64, but no operating rule anywhere in Title 63 that says a motorcycle is entitled to the full use of a lane, that two riders may travel abreast in one lane, or that passing between lanes of stopped or moving traffic is forbidden. Article 13 of Chapter 3, headed "Driving on Right Side of Roadway: Overtaking and Passing; Following," runs from § 63-3-601 to § 63-3-621 and addresses right-half driving, laned roadways, one-way roadways, meeting and overtaking, school buses, centre-of-highway driving, following distance and emergency vehicles. No section in it names motorcycles.

The general single-lane duty is therefore where the question lands, and it is unusually narrow as Mississippi drafted it. Section 63-3-603(1) opens with a condition: the rules that follow apply "Whenever any roadway has been divided into three (3) or more clearly marked lanes for traffic, except through or bypassing a municipality." Only inside that condition does paragraph (a) require a vehicle to be driven as nearly as practical entirely within a single lane and to stay there until the driver has ascertained the movement can be made with safety. On a four-lane divided highway with two lanes each way, and on any road inside a Mississippi municipality, paragraph (a) does not reach the rider by its own terms.

The contrast inside the same subsection is worth noting. Paragraph (e) does give a lane-sharing right, but it gives it to bicycles: persons riding bicycles may ride two abreast except on paths set aside for bicycles, provided they do not impede normal and reasonable traffic movement and, on a laned roadway, ride within a single lane. The Legislature wrote a two-abreast rule for one class of two-wheeler and none for the other.

Passing is governed separately. Section 63-3-609(a) requires the driver of an overtaking vehicle to pass to the left of the overtaken vehicle at a safe distance and to stay clear until safely past. Section 63-3-613 allows overtaking on the right in only two situations: when the vehicle ahead is making or about to make a left turn, and on a roadway with unobstructed pavement of sufficient width for four or more lines of moving traffic, where the section also declares that "The left lane shall be the preferred passing lane" and flatly forbids driving off the pavement or onto the shoulder to overtake. A rider slipping up the right-hand edge of a queue on a two-lane road is squarely outside § 63-3-613(2), and one who uses the shoulder violates it outright.

One further piece of § 63-3-603 catches riders and drivers alike. Subsection (2), added by Laws 2018, ch. 360, § 1, bars continuous travel in the outermost left lane of a multi-lane roadway where it impedes other traffic, with four listed exceptions for overtaking, closed right lanes, right lanes in disrepair, and preparing to exit left. A violation of subsection (2) carries its own fine of not less than $5.00 nor more than $50.00.

There is no lane-splitting citation in Mississippi because there is no lane-splitting offence. A rider who filters is charged under whichever general rule fits: § 63-3-603(1)(a) where the road has three or more marked lanes outside a municipality, § 63-3-613 where the pass was made on the right or on the shoulder, or § 63-3-1213 careless driving, which reaches anyone who drives in a careless or imprudent manner without due regard for the width, grade, curves, corner, traffic and use of the streets and highways.

00 and the statute itself declares it a lesser offence than reckless driving. 00 or ten days, or both, on a second or subsequent conviction. For Chapter 3 offences with no penalty of their own, § 63-9-11(2) supplies up to $100 or ten days for a first conviction, up to $200 or twenty days for a second within a year, and up to $500 or six months for a third within a year of the first. A rider with a valid Mississippi licence and no Chapter 3, 5 or 7 conviction in the previous three years may use § 63-9-11(3) to pay a $10 election fee, complete at least four hours of a court-approved traffic safety violator course within ninety days, and have the prosecution dismissed and the record expunged; § 63-9-11(4) denies that route to commercial driver's licence holders.
