Are there situations where turn lanes are not recommended, such as when they may create temporary sight obstructions?
There may circumstances where a left-turn lane may not be recommended at an unsignalized intersection due to horizontal and/or vertical sight restrictions. Horizontal sight obstructions may be able to be cost-effectively alleviated with an offset left-turn lane if sufficient width exists and additional right-of-way is not required. Vertical sight restrictions would be more difficult to account for, and may lead to prohibiting left turns at the intersection and providing for them via u-turns downstream or via a jughandle configuration.
