Form the Definitions section of the “Manual on Uniform Traffic Control Devices”, published by the U.S. Federal Highway Administration http://mutcd.fhwa.dot.gov

Exactly. “Lane” is one of those terms that actually has a meaning. Of course, I understand that common speech doesn’t necessarily follow that.
