When your line of sight is interrupted, a change in speed and position are necessary for re-establishing a clear line of sight to the driver’s path of travel.
To properly absorb information and steer a motor vehicle, a driver needs a wide range of view. The distance we can see ahead and to the sides will determine how well we can see. Our line of sight and field of view make up this area.
The line of sight is the fictitious path that connects our eyes and the place of concentration. A bend, slope, tree limb, structure, big car, etc. might obscure the line of sight. We must adjust our speed and position in order to keep a clear line of sight. Until the region is visible or the sightline is restored, a speed adjustment is required when sightlines are obstructed. For instance, in blind junctions are high-risk locations, therefore we should change our speed and lane position before entering the intersection.
