What should drivers always assume about large vehicles when navigating roundabouts?

Answer: B — They require a lot of space and do not pass them

When navigating roundabouts, it is important for drivers to always assume that large vehicles require a lot of space and that passing them can be hazardous. Large vehicles, such as trucks and buses, have wider turning radii and may need more room to maneuver than smaller vehicles. This is especially true in a roundabout, where the confined space and the need to navigate turns can pose challenges for larger vehicles. Acknowledging that large vehicles need extra space helps promote safety in roundabouts. For instance, they might swing wide or take longer to complete their turns, which could put smaller vehicles at risk if those drivers attempt to pass. By being aware of this, drivers can adjust their driving behavior to maintain a safe distance, allowing large vehicles the room they need to navigate the roundabout effectively and safely. This consideration for the dynamics of larger vehicles helps prevent accidents and contributes to smoother traffic flow.
