123.15(A) Sight triangles. Sight triangles are required and shall include the area on each

or property lines of intersecting
or accessways. Sight triangles shall be depicted on all planting plans.
123.15(B) Sight triangle dimensions.
123.15(B)(1) Sight triangle requirements for the intersections of all
and accessways shall conform with the criteria outlined in the following standards:
123.15(B)(1)(a) AASHTO’s A Policy on Geometric Design of
and Streets.
123.15(B)(1)(b) FDOT

123.15(B)(2) If an individual private driveway intersects with any
, no sight distance obstruction will be permitted within the ten-foot by 50-foot triangular area formed by the intersection of each side of the driveway and the
or property lines with the driveway side of the triangle being ten feet in length, the
side of the triangle being 50 feet in length, and the third side of the triangle being the line connecting the ends of the two other sides.
123.15(B)(3) These requirements may be reduced to ten-foot by 35-foot, subject to
approval, if the public
is a
with a posted speed limit of 25 mph or less.
123.15(B)(4) For all
intersections of private internal accessways, driveways, and/or private drive aisles, a minimum ten-foot by 25-foot sight triangle must be maintained from the intersecting edges of the travel way, with the ten-foot side of the triangle being along the minor drive aisle and the 25-foot side of the triangle being along the major drive aisle.
123.15(C) Clear visibility requirements. No
or planting (at mature growth) that exceeds two and one-half feet in height above
grade shall be permitted within required sight triangles. Exceptions are permitted if the lower canopies of
allow a clear line of sight between two and one-half feet and eight feet above adjacent
grade and the trunks of such
are sufficiently spaced or located so as to be unlikely to interrupt the line of sight.
