Why do large trucks require more space when turning?

• A. They weigh more and have longer wheelbases.
• B. They accelerate faster than cars.
• C. They can turn in tighter spaces.
• D. They are easier to steer.

Answer: (A)

Turning space is determined by the vehicle’s turning radius, which increases with wheelbase length and weight. A long wheelbase means the front and rear axles are farther apart, so when you steer, the rear wheels follow a wider arc. Add in the truck’s substantial weight, which adds momentum and makes the turn harder to control, and the overall arc you must clear during a turn becomes larger. That combination—more distance between axles and more mass—forces large trucks to need extra room to complete the turn safely without crossing into another lane or hitting obstacles. The other ideas don’t fit because heavier trucks don’t accelerate faster than cars, they don’t turn tighter, and steering a heavy truck is not easier.
