(1) When the left turn storage lane for the intersection (on the roadway abutting the generator) is longer than the lateral access requirement (above), left turn movements to and from the generator shall be prohibited. This will prevent delays for those vehicles making left turn movements at the intersection that are caused by vehicles turning left into the generator from the left turn storage lane. This will also prevent potential accidents and/or delays caused by vehicles turning left from the generator and crossing the left turn storage lane. | |||
(2) If the intersection includes two different roadway types, then the greater of the two distances shall be used. | |||
(3) Lateral access requirements do not apply to roadway types that are not listed above. | |||
