The Washington State Department of Transportation has released an animated video to help understand the new tolling / HOV lanes on I-405 from Lynnwood to Bellevue. As noted in the video it is illegal to change lanes with a double solid line and you can be ticketed. You can only legally change lanes with a dotted line to enter and exit these tolling / HOV lanes.  Attorney Paul Hanson handles HOV traffic violations as well as speeding tickets, improper lane change tickets and other traffic tickets.
