How about a lane just for transit and tractor trailers?

I've seen a proposal to allow big trucks to have their own lane on multi lane freeways of 3, or more lanes in each direction. Might be a good idea because I've always thought there should be a "bus only" lane for transit. Maybe buses and big trucks could team up to get this through, politically, plus getting through the constant clog of traffic.

Today's HOV lanes, through Seattle area, don't seem to work as they allow vehicles with only 2 occupants. There are so many 2 occupant vehicles that traffic seems just as clogged, in the HOV lanes, as in the regular lanes.

If transit could get through without being held up in traffic, maybe there would be less traffic as there would be more incentive for folks would use transit instead of private cars.

The only times I've recently been on that section of freeway, between Marysville and Seattle, I've been on a bus stuck in traffic in the HOV lane.

Last summer, when I was on Greyhound through that area, the bus took Highway 99 from Marysville to Everett and then went around by way of I-405 and I-90 to Seattle. This route hoping they could get around the traffic on I-5; HOV lanes and all.
