In astir states, postulation is simply a trial of patience for motorcycle riders who effort to obey nan law. Why beryllium down a agelong statement of cars erstwhile there's much than capable room for you to thrust betwixt nan vehicles? That is called lane filtering, and it is still forbidden successful astir states. That's starting to change, however. On July 1, 2025, lane filtering became ineligible successful Minnesota. As agelong arsenic nan different vehicles successful nan lane are moving slower than 25 mph, motorcyclists tin select nan lane, though they cannot beryllium moving much than 15 mph faster than nan surrounding traffic. Other drivers are moreover prohibited from blocking motorcyclists from doing this.
Minnesota isn't nan only authorities to let lane filtering, though. It's been ineligible successful Utah since 2019 connected roads pinch a posted velocity limit of 45 mph aliases less. Motorcycle riders cannot transcend 15 mph while lane filtering. Arizona made it ineligible successful 2022 pinch nan aforesaid rules. Montana made lane filtering ineligible successful 2021, allowing riders to walk cars that are going 10 mph aliases less, and nan riders cannot transcend 20 mph while filtering.
Colorado is different authorities to subordinate nan statement recently. On August 7, 2024, it became ineligible successful Colorado to walk betwixt stopped vehicles headed successful nan aforesaid direction. The motorcyclist can't thrust successful nan enarthrosis aliases recreation faster than 15 mph while lane filtering and tin beryllium cited pinch a $100 good if these rules aren't followed. California allows not only lane filtering, but besides afloat lane splitting. Lane splitting is erstwhile motorcyclists are allowed to thrust betwixt 2 lanes of postulation moving successful nan aforesaid direction, moreover astatine precocious speeds. California is nan only authorities successful nan national to let this.
Why are states starting to let lane filtering?

Fighting postulation during unreserved hr tin beryllium frustrating for conscionable astir immoderate driver, particularly if you support uncovering yourself stopped astatine lights down a agelong statement of different cars. That's why it tin beryllium peculiarly annoying to immoderate drivers to watch a motorcyclist rotation correct past them to nan beforehand of nan line. Why shouldn't nan motorcycle rider person to hold their move for illustration everyone else? But one use of lane filtering is reduced postulation congestion. If motorcyclists get to stock capable abstraction successful nan lane to move up front, there's much room astatine nan extremity of nan line, meaning postulation isn't backed up arsenic far. That's a triumph for everyone.
Believe it aliases not, lane filtering and splitting are safer successful immoderate ways than not lane filtering. The Colorado enactment that legalized lane filtering cited aggregate studies, including 1 successful California that recovered that motorcycle riders are 43% little apt to get rear-ended erstwhile lane splitting. Motorcycle fatalities person decreased successful California successful nan past fewer years, correlating pinch nan legalization of lane splitting successful nan state. The California Highway Patrol issued information tips connected nan practice, stating that it's nary much vulnerable than thing other you'd do connected a motorcycle. As agelong arsenic Californian motorcyclists travel nan rules, nary 1 should get hurt.
Studies successful different countries person shown that lane splitting is really adjuvant pinch reducing injuries to motorcyclists. One study titled "Motorcycle Accidents In-Depth Study," conducted by nan European Association of Motorcycle Manufacturers successful 2008, looked astatine 921 motorcycle accidents crossed Europe and concluded that motorcyclists were 7 times much apt to beryllium struck by different conveyance while stopped than while lane splitting. Another study successful Australia, whereby lane filtering was trialed for 8 weeks, saw zero accidents hap arsenic a consequence of lane filtering (and zero rear-end collisions among different motorcyclists), concluding that "lane filtering was a comparatively debased consequence riding activity for motorcyclists."
Why don't each states let lane filtering?
If lane filtering makes motorcyclists safer, why don't much states make it legal? Because it's not that simple. Yes, motorcyclists are little apt to get rear-ended erstwhile they lane filter, but Rider Magazine reports they are much than doubly arsenic apt to rear-end different vehicle. They are besides much apt to get into a side-impact collision. But supporters of lane filtering often constituent retired that these types of accidents are usually little fatal for motorcyclists than getting rear-ended, and nan information often backs them up.
However, we can't responsibility states that haven't legalized lane filtering yet. After all, roadworthy lanes were designed to beryllium wide capable for 1 vehicle, not a conveyance and a motorcycle. And it doesn't thief that American vehicles person been getting wider successful caller years, taking up moreover much room successful a lane. One of nan things they thatch you successful motorcycle information courses is to support a "safety cushion," a safe region successful each directions betwixt nan motorcycle and different vehicles. But lane filtering puts nan motorcyclist person to different vehicles, giving a rider little clip to respond if a car makes a abrupt move aliases a driver opens a door.
And past there's nan truth that galore drivers conscionable don't look to person a favorable sentiment of lane filtering. Though lane filtering and splitting person been communal practices successful California for years, a 2014 study conducted astatine nan University of California, Berkleley recovered that 60.8% of non-motorcyclists surveyed successful nan authorities disapproved of nan practice. Time will show whether lane filtering will beryllium accepted by much states. The nationalist whitethorn request to beryllium amended knowledgeable astir nan benefits earlier that happens. In nan meantime, obey nan laws and thrust safely.
