A motorcyclist's helmet camera footage shows a driver in Provo challenging the rider as he attempted to lane filter.
Here's a reminder on when a motorcycle can do this:
-At least two lanes of travel in each direction
-Speed limit of 45 mph or less
-Traffic at a complete stop
-Riders can’t exceed 15 mph
-Once the light turns green, the rider is meant to jump ahead of the cars and merge back into traffic.
