gore point
n.— «A while back you stated that it can be legal to cross a solid white line to merge into traffic, provided it’s safe to do so. Is it legal to cross two solid white lines? Making the merge from Mission Boulevard onto south I-880, there’s a long section where two solid lines come to a point. A driver could merge safely at that point, but is that legal?…No. This is what is called a gore point, and it is illegal to drive in an area set off by two solid white lines.» —“Roadshow: Hwy. 1 drivers have a long wait for extra lanes in Santa Cruz” by Gary Richards Mercury News (San Jose, California) Nov. 17, 2006.
