No, and Maryland says so in as many words
Maryland Transportation Article 21-1303, headed “Operating on laned roadways”, contains the sentence that settles it: a person may not operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.
There is no exception for stopped traffic, no speed threshold and no carve-out of the sort Utah, Montana, Arizona, Colorado and Minnesota added to their own codes. Filtering and splitting are the same thing under this wording, and both are prohibited.
That is the answer. What is more useful is the rest of the section, because Maryland’s motorcycle statute is one of the most complete in the country and two of its provisions work in the rider’s favor.
What else section 21-1303 gives you
The full lane, as an obligation on drivers
Every motorcycle is entitled to the full use of a lane, and a motor vehicle may not be driven in any manner that deprives a motorcycle of that full use.
This is written as a duty on the car, not a restriction on you. The driver who edges across to share your lane, or treats your machine as something to pass without leaving the lane, is the one in breach. It is the most useful sentence in the section for a Maryland rider and the one least quoted by the pages that rank for this question.
Two motorcycles abreast is expressly permitted
The statute prohibits operating more than two abreast in a single lane — which means two is lawful. And the full-lane entitlement above is expressly disapplied to motorcycles operated two abreast, which is the drafter acknowledging that a pair sharing a lane is a legitimate configuration rather than an infringement.
Riding side by side or staggered with one other machine is legal in Maryland. A surprising number of riders here believe it is not.
And two prohibitions that complete the picture
The operator of a motorcycle may not overtake and pass in the same lane occupied by the vehicle being overtaken — so squeezing past a car inside its own lane is out, separately from the between-lanes ban.
And the same-lane and between-lanes prohibitions do not apply to police officers in the performance of their official duties. A motorcycle officer filtering past a queue is not evidence that the rule has changed.
Where Maryland sits, structurally
After reading a dozen of these statutes side by side, American states sort into three groups on this question, and knowing which one you are in tells you what to expect.
| Group | What the code contains | States |
|---|---|---|
| Motorcycle statute with an exception | A dedicated motorcycle section banning between-lane riding, plus a carve-out with numbers attached | Arizona, Colorado |
| Motorcycle statute without an exception | The same dedicated section, banning it outright | Maryland, Washington |
| No motorcycle statute at all | General lane discipline and duty-of-care rules doing the work | Missouri, New Jersey |
Maryland is in the second group, and that is the clearest place to be as a rider. The answer is written down, it is unambiguous, and the same section tells you what you are entitled to. Compare Missouri, where nothing is written and the question is settled after the fact against a duty of care — see is lane splitting legal in Missouri — or New Jersey, in is lane splitting legal in New Jersey.
It also means any change would be an amendment rather than a new law: Maryland already has the section that the filtering states amended. That is a lower legislative bar than Missouri faces.
What riders actually get stopped for here
Because 21-1303 describes conduct rather than naming a maneuver, three ordinary things fall inside it, and riders are regularly surprised by all three.
Moving up the gap at a red light. Rolling forward between two columns of stopped cars to reach the stop line is operating between adjacent rows of vehicles. The statute contains no exception for stopped traffic — which is precisely the exception the five filtering states wrote into theirs.
Passing a car inside a wide lane. That is caught by a different subsection: the operator of a motorcycle may not overtake and pass in the same lane occupied by the vehicle being overtaken. A generous curbside lane does not become two lanes because there is room.
Using the shoulder to get past a queue. The shoulder is not a lane, but the maneuver still puts the machine between a row of vehicles and something else, and it gives up the full-lane position the statute otherwise protects.
None of that is exotic riding. It is the everyday queue behavior that is lawful in five western states and unlawful here, which is why the question keeps being asked.
A note on sourcing
Worth saying plainly. The text above was read through legal compilations rather than the state’s own publication: the Maryland General Assembly’s statute site and the usual repositories were unreachable on 30 August 2026, the former behind the same Cloudflare block that prevented us reading the Motor Vehicle Administration at all.
Where we have been able to read a statute at source in this series, we quote it directly — Washington’s RCW 46.61.608, Arizona’s ARS 28-903, Colorado’s C.R.S. 42-4-1503 and the enacted text of SB24-079, Missouri’s RSMo 304.012 and 304.015. Maryland’s is reported here at one remove, and it is the same standard four-part structure those states use.
How far you would have to ride
Nowhere near Maryland. The five states permitting a version of this are Utah since May 2019, Montana since 2021, Arizona since 2022, Colorado since August 2024 and Minnesota since July 2025 — and Colorado’s authorization is written to repeal itself on 1 September 2027.
Each sets different numbers: 15 mph for the rider in Utah, Arizona and Colorado; 20 mph in Montana, which is also the only state permitting the maneuver against traffic still moving. They are compared in full in lane filtering, and every other state is mapped in motorcycle lane splitting laws by state.
Maryland’s immediate neighbours all prohibit it too. Pennsylvania and Virginia to the north and south, Delaware to the east, and West Virginia to the west — none has a filtering exception. What does change at those borders is the helmet rule: Maryland requires one from every rider and passenger at any age, while Pennsylvania exempts qualifying adults, as set out in motorcycle helmet law Pennsylvania. The full table is in helmet laws by state.
The Maryland rules to pair with this
Licensing here runs on a season — the approved rider training is delivered from April to October — and the shorter of the two courses opens with a pass-or-leave exercise that carries no refund. Both are set out in motorcycle license Maryland and motorcycle safety course Maryland.
The machine’s paperwork is in motorcycle registration, and the federal crash figures that sit behind all of these rules are in motorcycle accident statistics.
Frequently asked questions
Is lane splitting legal in Maryland?
No. Maryland Transportation Article 21-1303 provides that a person may not operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles. There is no exception for stopped traffic.
Is lane filtering legal in Maryland?
No. Maryland’s statute makes no distinction between filtering past stopped traffic and splitting past moving traffic — the prohibition covers both.
Can two motorcycles ride side by side in Maryland?
Yes. The statute prohibits operating more than two abreast in a single lane, so two is permitted, and the full-lane entitlement expressly does not apply to motorcycles operated two abreast.
Does Maryland law protect a motorcycle’s lane?
Yes. Every motorcycle is entitled to the full use of a lane, and a motor vehicle may not be driven in any manner that deprives a motorcycle of that full use. A driver crowding you inside your own lane is in breach of it.
Why do police motorcycles filter through traffic in Maryland?
The prohibitions on same-lane overtaking and on operating between lanes do not apply to police officers in the performance of their official duties.
Which states near Maryland allow lane filtering?
None. Pennsylvania, Virginia, Delaware and West Virginia all prohibit it. The nearest states permitting a version of it are Utah, Montana, Arizona, Colorado and Minnesota.
