{{@|Allowing median U-turns}}: testing
To allow a double-left or double-right turn through the median segment, break any one of the [[#Preventing median U-turns|above conditions]]. For example:
* To allow median U-turns in both directions, break condition #2 by making the median segment (B) {{#expr: {{padleft:|2|{{:Routing_penalties/U-turn_minimum|greater}}}} + 1}} meters ({{#expr: {{#expr: {{padleft:|2|{{:Routing_penalties/U-turn_minimum|less}}}} + 1}} * 3.2808 round 2}} feet) or ''longer''
* To allow a U-turn from only one direction, first set up U-turn prevention for both directions. Break condition #3 on the side where U-turns are allowed. Increase or decrease the angles so that the in and out segments (A and C) are [[#Checking for parallel incoming and outgoing segments|not parallel]]. A [[Glossary#mDL|micro-dogleg]] can be used to change the angle without changing the appearance of segment.
