Alabama Bans Lane Splitting Outright, Yet Lets Two Riders Share a Lane

Alabama packs a prohibition, an entitlement, an allowance and an exemption into five short subsections, so the answer depends on which one you are reading. Subsection (a) grants the entitlement: all motorcycles are entitled to full use of a lane, and no motor vehicle may be driven in a manner that deprives a motorcycle of that full use. That is the provision a rider relies on when a car tries to share the lane. But the same subsection ends by disapplying itself: the entitlement "shall not apply to motorcycles operated two abreast in a single lane." Pairing up with another rider is therefore a trade. Alabama permits it, and the moment you do it, the statutory claim to the whole lane drops away for both riders.

Subsection (c) is the lane-splitting ban, and it is unconditional. It reaches operating a motorcycle "between lanes of traffic" and, separately, "between adjacent lines or rows of vehicles." That second phrase closes the gap a narrower ban would leave open, because it does not depend on painted lane lines. There is no speed ceiling written into the Alabama subsection, no requirement that surrounding traffic be moving, and no carve-out for filtering to the front at a red light. A rider creeping between two stopped columns on a backed-up stretch of I-65 is squarely inside subsection (c). Alabama also has no pilot program and no self-repealing filtering experiment on the books; the ban has stood in this form since Acts 1980, No. 80-434.

Subsection (b) is a different offense that often gets confused with splitting. It forbids a motorcycle operator from overtaking and passing in the same lane occupied by the vehicle being overtaken. That covers the rider who stays inside the lane markings and squeezes past a slower car on the same strip of asphalt, which is not lane splitting in the usual sense but is prohibited by its own sentence.

Subsection (d) sets the ceiling on the allowance implied by subsection (a): motorcycles shall not be operated more than two abreast in a single lane. Three riders abreast is an offense on its face.

Subsection (e) is the only exemption, and it is narrow. It disapplies subsections (b) and (c) to police officers in the performance of their official duties. It does not disapply subsection (d), so even a police motorcycle unit is held to two abreast, and it grants nothing to other emergency riders, escorts or funeral processions.

The rest of Alabama's motorcycle article fills in the conduct rules that go with this. Section 32-5A-241 requires the operator to ride on the permanent and regular seat, forbids carrying a passenger unless the machine is designed for more than one person and has a seat for the passenger at the rear or the side, requires every rider to sit astride the seat facing forward with one leg on each side, forbids carrying any package or bundle that keeps the operator from keeping both hands on the handlebars, and forbids carrying anyone in a position that interferes with control or with the operator's view. Section 32-5A-245 requires approved headgear and shoes, and § 32-5A-240 sets the licensing requirement for operating a motorcycle. Section 32-5A-243 separately prohibits clinging to other vehicles, and § 32-5A-244 governs footrests and handlebars.

Section 32-5A-242 sets no penalty of its own, so the general penalty in Ala. Code § 32-5A-8 applies. Subsection (a) makes it a misdemeanor to violate any provision of the chapter or of Title 32 unless the violation is declared a felony. Subsection (b) fixes the amounts where no other penalty is provided: a first conviction draws a fine of not more than $100 or imprisonment for not more than 10 days; a second offense committed within one year after the date of the first draws not more than $200 or not more than 30 days or both; a third or subsequent offense within one year after the first draws not more than $500 or up to three months or both.

A splitting citation is written roadside. Ala. Code § 32-5-310 obliges peace officers including state troopers, sheriffs and their deputies, constables, municipal police officers and marshals, county police, license inspectors and specially appointed state officers to enforce the chapter and to arrest without a warrant for an offense committed in their presence. A rider arrested without a warrant may elect to be taken immediately before the nearest court with jurisdiction; otherwise the officer must take a bail bond of not more than $300, may not accept a cash bond, and must report the bond to the court within 18 hours.

Beyond the fine, a splitting citation is a moving violation that a rider's insurer and the Alabama Law Enforcement Agency driver record will both reflect, and in a collision it supplies the other driver with a statutory violation to point at.
