What is a common visibility issue associated with step vans and delivery trucks?

The correct answer highlights a significant safety concern regarding step vans and delivery trucks: they have poor rearward vision. These vehicles typically have larger blind spots and limited rear visibility, making it challenging for drivers to see directly behind them. This can pose serious risks when maneuvering in tight spaces or reversing, as the driver may not be able to spot pedestrians, cyclists, or smaller vehicles.

In contrast to the correct answer, the other options inaccurately suggest that visibility issues with these vehicles are minimal or mitigated by technology. For instance, while some vehicles might be equipped with advanced camera systems, it is not a universal feature for all step vans and delivery trucks, and many still rely primarily on mirrors, which do not offer a comprehensive view. This disparity emphasizes the need for greater awareness of surroundings when operating such large vehicles. Understanding these visibility challenges is crucial for safe driving practices, particularly in urban and congested areas where delivery trucks are common.
