==Description== [[File:MichiganLeftSigns.png|thumb|Two versions of signs posted along an intersecting road or street at an intersection.<br/>'''Top:''' most commonly used; state of Michigan standard.<ref>{{cite web |author = Michigan Department of Transportation, Traffic and Safety division |url = https://mdotjboss.state.mi.us/TSSD/tssdHome.htm |title = Standard Highway Signs: Route Marker Signs |page = 101 |date = 2012 }} Sign M8-5.</ref><br/>'''Bottom:''' lesser-used variant.]] The design occurs at [[intersection (road)|intersection]]s where at least one road is a [[divided highway]] or [[boulevard]], and left turns onto—and usually from—the divided highway are prohibited. In almost every case, the divided highway is multi-laned in both directions. When on the secondary road, drivers are directed to turn right. Within {{convert|1/4|mi|m}}, they queue into a designated [[Turnaround (road)|U-turn (or cross-over) lane]] in the [[median (road)|median]]. When traffic clears they complete the [[U-turn]] and go back through the intersection. Additionally, the U-turn lane is designed for one-way traffic. Similarly, traffic on the divided highway cannot turn left at an intersection with a cross street. Instead, drivers are instructed to "overshoot" the intersection, go through the U-turn lane, come back to the intersection from the opposite direction, and turn right. When vehicles enter the cross-over area, unless markings on the ground indicate two turning lanes in the cross-over, drivers form one lane. A cross-over with two lanes is designed at high-volume cross-overs, or when the right lane turns onto an intersecting street. In this case, the right lane is reserved for vehicles completing the design. Most crossovers must be made large enough for semi-trailer trucks to complete the crossover. This large cross-over area often leads to two vehicles incorrectly lining up at a single cross-over. A Michigan left generally allows through traffic on the minor crossroads to proceed straight across the major road or highway, especially on the more heavily traveled minor roads. Its design also is promoted as part of the Federal Highway Administration's [[Every Day Counts initiative]] which started in 2011.<ref>{{cite book |first1 = Bastian |last1 = Schroeder |first2 = Chris |last2 = Cunningham |first3 = Brian |last3 = Ray |first4 = Andy |last4 = Daleiden |first5 = Pete |last5 = Jenior |first6 = Julia |last6 = Knudsen |date = August 2014 |title = Diverging Diamond Interchange Informational Guide |url = https://rosap.ntl.bts.gov/view/dot/29474/dot_29474_DS1.pdf?download-document-submit=Download |location = Washington, DC |publisher = Federal Highway Administration Office of Safety }}</ref>
