The sight distance rule is a guideline used in road design to ensure that drivers have adequate visibility to react to obstacles or changes in the road ahead. It typically involves calculating the minimum distance a driver should be able to see, which allows for safe stopping or maneuvering. This distance is influenced by factors such as vehicle speed, road conditions, and the driver's reaction time. Proper adherence to this rule helps enhance safety and reduce the likelihood of accidents on roadways.

:parallax error occurs when the line of sight or measure is not at right angles ( perpendicular ) to the objects being measured. Any distance between the object and the measuring reference ( for example a rule ) will cause a misreading. This error will increase as the distance between the object and the reference increases.
An indicated distance, usually within sight.
Factors affecting sight distance include driver reaction time, vehicle speed, road alignment and curvature, vertical and horizontal curves, weather conditions, obstructions in the roadway or along the roadside, and the presence of signage and pavement markings. Additionally, vehicle characteristics such as headlight visibility and windshield condition can also impact sight distance.

One "Click" is not a measurement of distance; it is a rifle sight adjustment. By moving the trajectory or elevation adjustments of the rear sight of the M1 or M16, the sight picture is moved by one inch at twenty-five meters, right or left, up or down.One "Klick" is military shorthand for the distance of one kilometer.
100 yards is the most effective distance to sight in primarily. However, if you know the distance your rifle will be performing at, then sight in as close to that as you can. For instance, if you are going to be hunting open land i.e Wyoming, then youll most likely want to be set in at 200 considering typically, you will be shooting longer distances. For regular white tail hunting, 100 yards is perfect.
