suicide lane
n.— «If a driver coming toward you in the other inside lane has to come to a sudden stop, his throwing his weight on the brake pedal will tend to make him twist his steering wheel so that his car veers into your lane. That’s what can make the inside lane on a busy highway the “suicide lane.”» —Independent Star-News (Pasadena, California) Dec. 8, 1957. (source: Double-Tongued Dictionary)
