Which statement regarding blind spots is true?

Answer: B — Large trucks have bigger blind spots than most passenger vehicles

Blind spots are areas around a vehicle that cannot be directly observed by the driver while driving or checking mirrors. It's true that large trucks have bigger blind spots than most passenger vehicles due to their size and shape. Trucks have a more significant cabin height and larger dimensions, which create larger blind spots. These areas can extend several lanes to the sides and rear of the vehicle, making it essential for other drivers to be aware of their presence and exercise caution around larger vehicles. Regarding the other options, simply having outside mirrors on each side does not completely eliminate blind spots, as they are still present; checking a rear-view mirror will only provide visibility directly behind and not the sides; and not all vehicles have the same size blind spots, as different vehicle designs and sizes result in varying blind spot dimensions. Understanding the specific characteristics of blind spots is crucial for safe driving, especially around larger vehicles.
