Where lane splitting and filtering are legal

• Between-lane riding prohibited in all traffic, moving or stopped (§ 32-5A-242(c)).
• Passing in the same lane occupied by the overtaken vehicle prohibited (§ 32-5A-242(b)).
• No more than two motorcycles abreast in a lane (§ 32-5A-242(d)).
• Police officers on duty exempt from (b) and (c) (§ 32-5A-242(e)).

• Between-lane riding prohibited, moving or stopped (13 AAC 02.427(b)).
• No passing in the same lane occupied by the overtaken vehicle (13 AAC 02.427(b)).
• Two abreast in one lane allowed only by consent of both riders; never more than two (13 AAC 02.427(a)).
• Police officers on duty exempt (13 AAC 02.427(c)).

Note: Alaska’s rule is in a Department of Public Safety regulation (13 AAC 02.427), not a statute.

• Two-wheeled motorcycles only.
• Traffic being passed must be stopped.
• At least two adjacent lanes in the same direction.
• Speed limit 45 mph or less; rider at 15 mph or less.

• No statute expressly permits or prohibits lane splitting or filtering.
• The general laned-roadway rule (§ 27-51-302) requires driving as nearly as practicable within a single lane. Enforcement against splitting would rest on this or on careless-driving provisions.

Note: Arkansas’s official code is hosted by LexisNexis and could not be opened directly. This status rests on HB 1755 (2023), a bill on the Legislature’s site that would have added lane splitting to the motorcycle chapter; it was sent to interim study and did not pass.

• Two-wheeled motorcycles, between rows of stopped or moving vehicles in the same lane.
• No speed limit or speed difference is set in the statute.
• The basic speed law and safe lane-change rules still apply.

• Two-wheeled motorcycles only.
• Traffic being passed and traffic in adjacent lanes must be stopped.
• Rider at 15 mph or less; stop filtering when traffic moves.
• Not on the shoulder, to the right of the right-hand lane on non-limited-access roads, or in opposing lanes.
• Expires September 1, 2027 unless extended.

Note: The law asks the Colorado Department of Transportation to study the safety effects of filtering. When we checked on October 26, 2026, we did not find a bill extending the 2027 expiry, but that search was not exhaustive.

• Riding between lanes of traffic prohibited (§ 14-289b(b)(2)).
• Passing a non-motorcycle vehicle in the same lane prohibited (§ 14-289b(b)(1)).
• No more than two motorcycles abreast (§ 14-289b(a)).

• No Delaware statute expressly prohibits or permits lane splitting or filtering.
• General rule: a vehicle 'shall be driven as nearly as practicable entirely within a single lane' and may not leave it until the move can be made safely (§ 4122(1)). Riders between lanes risk citation under this or careless-driving provisions.

• General rule: on roadways with two or more marked lanes, a vehicle 'shall be driven as nearly as practicable entirely within a single lane' (18 DCMR § 2201.6(a)).

• No more than two abreast (§ 316.209(4)).
• Police officers and firefighters on duty exempt (§ 316.209(5)); a violation is a noncriminal moving infraction under ch. 318 (§ 316.209(6)).

• Between-lane riding prohibited, moving or stopped (§ 40-6-312(c)).
• No passing in the same lane occupied by the overtaken vehicle (§ 40-6-312(b)).
• No more than two abreast (§ 40-6-312(d)).
• Police officers on duty exempt from (b) and (c).

Note: Georgia’s official code is hosted by LexisNexis. We read § 40-6-312 as reprinted in HB 461 (2025-26) on the General Assembly’s site. HB 461 would have allowed passing stopped traffic at signals at up to 15 mph; it was reported by committee on February 24, 2026 but never got a floor vote.

• Between-lane riding prohibited, moving or stopped (§ 291C-153(c)).
• No passing in the same lane occupied by the overtaken vehicle (§ 291C-153(b)).
• Police officers on duty exempt (§ 291C-153(e)).
• Shoulder use: the 2018 'designated shoulder' program for two-wheeled motorcycles (Act 218, SLH 2018) ran January 1, 2019 to December 31, 2020 and is no longer law.
• Since Act 73 (SLH 2026, effective on approval June 3, 2026), a new HRS 291C section bars driving on a roadway shoulder by any vehicle, except authorized emergency vehicles (§ 291C-26) or during hours the Department of Transportation designates. Fine $250 for a first violation.

Note: Hawaii let motorcycles use some designated shoulders in stopped traffic from 2019 through 2020 (Act 218 of 2018). That program expired, and Act 73 of 2026 now bars most shoulder driving.

• No Idaho statute expressly prohibits or permits lane splitting or filtering.

Note: No Massachusetts statute uses the words “between lanes”. We list it as prohibited because the same section requires riding within a single lane and bars passing within a lane.

• Riding between lanes of traffic, or between adjacent lines or rows of vehicles, is prohibited (moving or stopped traffic). Police officers on duty are exempt where noted.

• Up to 25 mph.
• No more than 15 mph faster than traffic in the lanes being passed.

Note: Bills to repeal or narrow this law (HF 663, SF 910 and HF 3159) were introduced in 2025. When we checked the Legislature’s status pages on October 26, 2026, none had moved past committee.

• No Mississippi statute was found that expressly permits or prohibits lane splitting/filtering (based on 2016 bill text; current code not opened).
• General single-lane rule applies on roadways with 3+ marked lanes.

Note: Mississippi’s official code is hosted by LexisNexis and could not be opened directly. We read § 63-3-603 as reprinted in HB 854 (2016), a lane splitting bill on the Legislature’s site that did not pass.

• The single-lane rule, R.C. 4511.33(A)(1), applies. A violation is a minor misdemeanor.
• HB 776 (136th General Assembly) would allow filtering. It is in committee and is not law.

• 47 O.S. § 11-1103(D) prohibits passing other vehicles between lanes of traffic traveling in the same direction. This covers both splitting and filtering, since it is not speed-limited.

Note: Oregon has come close: SB 574 (2021) passed both chambers and was vetoed. SB 422 (2023) and HB 3542 (2025) died in committee.

• Motorcycles may not overtake and pass in the same lane as the vehicle being overtaken (§ 3523(b)).
• Motorcycles may not be operated between lanes of traffic or between adjacent lines or rows of vehicles (§ 3523(c)).

• General laned-roadway rule (§ 31-15-11(1)) and overtaking-on-the-right limits (§ 31-15-5) apply to all vehicles, so riding between lanes is likely to be cited under these.
