Which statement about blind spots is true?

The statement that large trucks have bigger blind spots than most passenger vehicles is accurate. This is due to the size and shape of the trucks, which inherently creates larger areas around them that may not be visible to the driver. These larger blind spots can hinder the driver's ability to detect nearby vehicles or pedestrians, posing safety risks.

Understanding the dimensions of a vehicle and its blind spots is crucial for safe driving, especially for larger vehicles like trucks and buses. This knowledge allows all drivers to take additional precautions, such as avoiding lingering in these areas and using proper signaling when changing lanes or merging.

The other options are misleading in their assumptions. Not all vehicles share the same blind spot size; it varies by vehicle type. Blind spots are not exclusive to turning; they exist whenever a vehicle is in motion. Additionally, while motorcycles do have blind spots, they are not the only vehicles with this characteristic. Knowing which vehicles have larger blind spots helps all drivers navigate safely on the roads.
