Which statement is true regarding towing?

Answer: B — Fuel efficiency is reduced by as much as fifty percent

When towing, it is factual that fuel efficiency can be significantly reduced, sometimes by as much as fifty percent. This decrease occurs because towing adds considerable weight to the vehicle, which requires more energy to move. The engine has to work harder to overcome the added resistance from both the weight of the trailer and any increased aerodynamic drag. The impact on fuel efficiency can vary based on factors like the vehicle type, the weight being towed, and driving conditions, but a substantial reduction in fuel efficiency is the most common outcome when towing. This understanding is essential for drivers to account for when planning trips or considering the costs associated with towing. It's important to note that when towing, braking distance is typically increased due to the added weight, making it necessary for drivers to adapt their driving behavior, including allowing for longer stopping distances. Similarly, acceleration does not increase; in fact, towing can lead to longer acceleration times as the vehicle struggles with the additional mass. Maneuvering distance may also be impacted, as the increased length and weight of the vehicle/trailer combination can affect how easily a driver can turn or change direction.
