One of the routes I take is a 4 lane arterial (40mph limit). Where it crrosses the interstate, there is an enterance ramp off the interstate onto the arterial. Needless to say the drivers coming off the interstate are entering traffic at well over 40.

I've heard two conflicting proposals for crossing the on ramp while travelling on the arterial

1. Stay in the through lane moving toward the middle of the through lane where the "on" ramp intersects; or

2. Cross the on ramp and ride back onto the arterial using the right side of the ramp.

So- who prefers what method and why?
