What can affect your ability to see other vehicles when passing?

The height and length of a combination vehicle can significantly impact your ability to see other vehicles when passing. Larger vehicles create bigger blind spots, which can obscure your view of vehicles approaching from either side or in adjacent lanes. This is particularly true when you're changing lanes or merging, as the longer the vehicle, the more space it occupies on the roadway, thereby affecting your visual range.

Drivers need to be particularly aware of their vehicle's size to ensure they have a clear line of sight before making any lane change or passing maneuver. Understanding the limitations posed by the dimensions of your vehicle allows for safer driving practices, as you can account for these factors by ensuring you check mirrors and blind spots thoroughly before acting.

While road conditions can impact visibility and weather factors, such as fog or rain, also play a critical role, the inherent physical characteristics of the vehicle itself—its height and length—most directly affect your ability to see potential hazards or other vehicles on the road when passing.
