simultaneous left turns from opposing approaches, it may be necessary to laterally offset
the double left turn lanes on one approach from the left turn lane(s) on the opposing
approach to avoid conflicts in turning paths. Figure 2.38 provides an example. All
turning paths of double left turn lanes should be checked with truck turning templates
allowing 2 ft (0.6 m) between the tire path and edge of each lane. Expanded throat
widths are necessary for double left turn lanes as illustrated in Fig. 2.39.
