There are 3 types of sight distance: minimum stopping, minimum passing, and minimum at intersections. Refer to Development Standards Chapter 5, Section 505-H, and Drawing 505.H-1 for more information.

• Minimum Stopping Distance is the distance that a driver can see an object on the roadway and safely stop before making contact. It is based on the change in percent grade (slope) and design speed of the roadway.
• Minimum Passing Sight Distance is the distance that a driver can safely pass another vehicle and is based on the design speed of the roadway with consideration to roadway curves and intersections.
• Minimum Sight Distance at Intersections is a distance that a driver or pedestrian can see an approaching vehicle driving on the crossroad. It is based on the design speed of the crossroad. This is the sight distance used to evaluate driveway locations.
