A new law impacting motorcycle riders is going into effect in Arizona starting Saturday, September 24.

Motorcycle lane-filtering will now be legal in Arizona. This means motorcycles will be able to move alongside and pass a car when the car is stopped in the same lane. 

Here are the legal requirements for the law:

-Vehicles have to be stopped for motorcycles to legally go around them.

-This is only allowed on streets where the speed limit is 45 miles per hour or less.

-The motorcycle cannot go faster than 15 miles per hour, as it is passing by stopped vehicles.

-Motorcyclists cannot use the shoulder as a passing lane.
