Is Lane Splitting Legal in Utah? What Riders Need to Know for the 2026 Season

Warmer weather is back in Utah, garages are opening, and motorcycles are coming out of winter storage. With the riding season ramping up, one of the most common questions Utah riders ask every spring is some version of: "Is lane splitting legal in Utah?"

The short answer is no — but Utah does allow a narrower practice called lane filtering, and the rules around both got stricter on January 1, 2026. If you ride in Utah, or represent clients who do, here is what the law actually says right now.

Lane Splitting vs. Lane Filtering: They Are Not the Same Thing

People often use "lane splitting" and "lane filtering" interchangeably, but under Utah law they are distinct:

Lane splitting generally means riding a motorcycle between lanes of traffic that is moving — the California-style maneuver where a bike threads between cars traveling at freeway speeds.
Lane filtering in Utah means a motorcycle overtaking and passing another vehicle that is stopped in the same direction of travel in the same lane, at very low speed.

Utah permits the second; it does not permit the first.

Lane Splitting Is Illegal in Utah

Utah law generally requires vehicles — including motorcycles — to be driven as nearly as practical entirely within a single marked lane. Riding between lanes of moving traffic does not fit within the narrow lane filtering exception discussed below, and it can be cited as an improper lane-use violation or, depending on the circumstances, as reckless driving.

That prohibition was reinforced in 2025 when the Utah Legislature passed HB 190, Motorcycle Amendments, signed by Governor Spencer Cox on March 25, 2025. The Utah Highway Safety Office describes HB 190 this way:

"Effective 1/1/2026, this bill provides requirements for the location and visibility of a motorcycle license plate. It also prohibits lane splitting and performing a wheelie on a highway. The bill requires the Driver License Division to suspend a motorcycle endorsement for certain violations and requires the motorcycle to be impounded under certain circumstances."

In plain English, as of the 2026 riding season:

Lane splitting (between moving lanes) is expressly prohibited on Utah highways.
Wheelies on a highway are prohibited.
Motorcycle license plates must be positioned so they are clearly visible — you can no longer tuck the plate under the wheel well or sideways.
The Driver License Division is required to suspend a motorcycle endorsement (or the driver license itself, if the rider has no endorsement) for certain violations, and officers can impound the motorcycle in defined situations.

The bill text and legislative history are available on the Utah Legislature's site: HB 190 (2025 General Session).

Lane Filtering Is Legal — But Only Under Strict Conditions

Utah was the first state in the country to legalize lane filtering, through HB 149 in the 2019 legislative session. HB 190 did not repeal lane filtering. It remains legal in Utah, but only when every one of the statutory conditions is met.

According to the Utah Highway Patrol's Ride to Live Utah program, a motorcyclist may lane filter only when all of the following are true:

The road has two or more lanes of traffic in the same direction.
The posted speed limit is 45 mph or less.
Traffic is completely stopped (for example, at a red light or behind a crash).
The motorcycle is traveling at 15 mph or less while filtering.
The movement can be made safely.

Once traffic starts moving again, the rider must merge back into a lane as soon as it is safe to do so. Continuing to ride between lanes after traffic resumes is no longer "filtering" — at that point, it becomes lane splitting, which is not legal in Utah.

A few practical takeaways for riders:

Lane filtering on interstate freeways and 55+ mph highways is not allowed, because the posted speed limit requirement is not met.
Filtering between two rows of rolling traffic — even slow rolling traffic — is not allowed, because traffic must be fully stopped.
"The movement can be made safely" is a real legal standard. Officers and juries will look at visibility, mirror use, lane width, and the behavior of nearby drivers if something goes wrong.

What Changed on January 1, 2026

HB 190 did three big things that riders should have on their radar this season:

1. Tougher enforcement for lane splitting and related violations

HB 190 gives the Driver License Division the authority — and in some cases, the obligation — to suspend a rider's motorcycle endorsement for certain violations. If the rider has no motorcycle endorsement, the suspension can attach to the driver license instead.

Public reporting on the bill has described an escalating structure along the lines of a 90-day suspension for a first qualifying offense, a 180-day suspension for a second, and potential revocation of the motorcycle endorsement for repeat offenders, with the ability for law enforcement to impound the motorcycle at the scene. Those specifics are administrative and will be applied by DLD and the courts; riders cited under HB 190 should get case-specific legal advice rather than relying on general descriptions.

2. Clearer license plate rules

Motorcycle plates must be mounted so they are clearly visible — no sideways "tucked" plates, no plates hidden under the wheel well, no frames or covers that obscure the plate. This is one of the simplest things a rider can check before the first ride of the season.

3. Express ban on wheelies on a highway

Performing a wheelie on a highway is now specifically prohibited by HB 190. Depending on how the conduct is charged, this can overlap with reckless driving and other traffic offenses that carry their own fines, points, and potential suspension consequences.

Why Utah Tightened Its Motorcycle Laws This Year

The backdrop to HB 190 is a multi-year rise in motorcycle fatalities in Utah. Lawmakers and the Utah Highway Safety Office have repeatedly pointed to that safety record as the reason for pulling back on gray areas in the law — particularly lane splitting on higher-speed roads — and for giving the Driver License Division more tools to take risky riders off the road.

Lane filtering itself, by contrast, has generally been associated with fewer rear-end collisions at stoplights and less exposure time for motorcyclists at intersections. That is why the Legislature kept lane filtering intact and focused the new penalties on lane splitting, wheelies, and plate-obstruction issues.

Quick Reference for Utah Riders in 2026

Lane splitting (between moving lanes): Illegal.
Lane filtering (between fully stopped vehicles): Legal only when all of the following are true:
- 2+ lanes in the same direction
- Posted speed limit 45 mph or less
- Traffic completely stopped
- Motorcycle at 15 mph or less
- The movement can be made safely
Wheelies on a highway: Illegal.
Plate position: Must be clearly visible; no under-wheel-well or sideways mounts.
Penalty exposure: Citations, fines, possible reckless-driving charges, motorcycle endorsement (or driver license) suspension, and possible motorcycle impoundment under HB 190.

What This Means for Utah Riders and Their Lawyers

If you ride in Utah, the rules going into the 2026 season are clearer than they have been in years:

Treat lane filtering as a narrow, stop-and-go tool — not a way to move faster through traffic.
Assume that anything that looks like California-style lane splitting will be cited in Utah.
Expect officers to take plate-visibility and wheelie violations seriously, because HB 190 specifically told them to.

For attorneys representing motorcyclists, HB 190 adds a new administrative layer on top of the traditional traffic-court analysis. A single citation can now trigger both a criminal or infraction case and a DLD suspension action tied to the motorcycle endorsement. Tracking those parallel tracks — along with the underlying statutory elements of lane filtering under HB 149 — is going to matter more in 2026 than it did a year ago.
