What the fuck does "slow traffic keep right" mean?

toronto user should have driven on the shoulder

Driving too fast in a lane adjacent to an onramp is dangerous, especially a bunch of cars all driving faster than what a car and especially truck can reasonably accelerate to in order to merge with traffic. Where I live we have a huge speeding problem and cars often are forced either back off the highway or onto the shoulder because the on ramps simply aren't long enough to have them merge with a bumper to bumper traffic going 25mph over the design speed of the road, especially trucks who are electronically limited to far below that speed and who couldn't travel that fast safely anyway.

I here many stories about people driving even at "normal" speeds in the right lane of a 4 lane section of autobahn and have to stand on the brakes for a merging car or truck because they couldn't safely move over left to let them in. I think part of the reason many autobahns are now 6 lanes is to keep the right lane closer to 50-60mph, a middle lane with a mode of around 80mph (the advisory speed), and the right lane for faster traffic that will temporarily more over to the center when safe to let approaching cars by. This drastically reduces lane changes in the scope of the average driving habits there and makes merging much safer because all entrances and exits are to the right in unrestricted zones. It also helps to reduce the congestion in the right lane making merging easier.

I think he was taking city streets. Also driving on the shoulder of a Toronto freeway is suicide
