California is still the only state that allows all-out lane splitting, and many people oppose that, but the movement to add lane filtering to more states is growing. In Utah, a recent bill passed that allows lane filtering. This is different than lane splitting but works under some of the same principles.
When the speed limit on a road is 45 mph or less and car traffic is stopped—like at an intersection— then you can filter through traffic. This will move motorcyclists more easily through congested urban areas. It’s a win for motorcyclists and something that more states should consider.
With all that said, there are some rules riders need to abide by to properly lane filter. First off, you must be on a motorcycle (no trikes or reverse trikes). Second, there must be two lanes of traffic at least. Third, as I mentioned above, the speed limit must be 45 mph or less. Fourth, you can’t ride faster than 15 mph while lane filtering. Fifth, you can’t filter lanes if the cars are not stopped.
The Utah law, HB0149, will expire in 2022 if the legislation doesn’t take further steps. Also, the law leaves a gray area. It says you must filter lanes in a safe manner. What people consider safe varies, so that may be a point of contention between motorcyclists and law enforcement.
As Common Tread pointed out, other states such as Connecticut, Maryland, and Oregon have similar laws in the works. It will be interesting to see if they shake out in the same manner that Utah’s did. I certainly hope so. While I can understand people’s concerns with lane splitting, lane filtering just makes sense. Also, it’s not like you have to do it. If you’re not comfortable with it, just wait with the cars. No harm there.
