The principle highlights a critical safety consideration when sharing roadways with large commercial vehicles. It asserts that if a passenger vehicle driver’s visibility is compromised, a truck driver’s visibility is likely compromised to an even greater extent due to the size and configuration of the truck. For example, if heavy rain significantly reduces visibility for a car, the larger blind spots inherent in trucks mean the truck driver likely has even less visual information about surrounding vehicles.
Adhering to this principle promotes safer driving practices and reduces the risk of accidents. Understanding the limitations of a truck driver’s field of vision, especially in adverse conditions, is crucial for all drivers. Historically, many collisions between passenger vehicles and large trucks occur due to passenger vehicle drivers positioning themselves in areas where the truck driver’s visibility is severely restricted or non-existent. Recognizing this fact allows drivers to make more informed decisions, such as avoiding prolonged driving in a truck’s blind spots and maintaining a safe following distance, which can prevent dangerous situations.
