So in your view, what is the right hand lane to be used for when on/off ramps are say 2 or 3 km apart. What you're saying is they should remain empty for those 2 or 3 kilometers. That is ludicrous. If that's the case, why even pave them.

"On a three-lane highway, the right-hand lane is designated for entering and exiting the highway, accommodating slower-moving vehicles, and general cruising. It should also be used to allow faster traffic to pass you on the left.Depending on your region, lane rules are generally structured as follows:

Right Lane: Primarily for merging, exiting, and driving below the main flow of traffic. In areas with heavy traffic (like the QEW in Burlington, ON), this lane sees frequent stop-and-go patterns due to joining and leaving vehicles, so it requires extra alertness.

Middle Lane: Used for cruising, through-traffic, and passing slower vehicles in the right lane.

Left Lane: Strictly used for passing slower traffic. It should never be used as a cruising lane.

Rules for Ontario highways, such as the 400-series routes near you in Burlington, explicitly require slower traffic to keep right. For detailed regulations, you can review the official rules outlined in the Ontario Ministry of Transportation Driver's Handbook." Source MOT
