Section R. 247.232 - Clear vision and buffer areasRule 32.
(1) At an intersection or railroad crossing where the department owns limited access right-of-way to provide a clear vision area, a driveway shall not enter or cross that clear vision area. At an intersection or railroad crossing where the department has an easement for a clear vision area, a driveway shall not enter or cross that clear vision area if another reasonable access point is available.(2) Adjacent to and on both sides of a driveway, a buffer area between the right-of-way line and the pavement edge shall be used, as determined by the department, to provide a physical barrier between highway traffic and activity on private property. A buffer area is needed to provide an unobscured vision area and to prevent potentially hazardous movement of vehicles, especially at undesirable angles of approach, from and to the highway. The buffer area shall consist of a lawn area, a low shrub area, a ditch, or equivalent. Where encroachment of vehicle parking on the buffer area takes place or may take place, the department may require the buffer area to be established by guardrail, guard posts, curb, or equivalent.Mich.
