What is a sign of a potentially confused driver?

Answer: B — Hesitation and frequent lane changes

A sign of a potentially confused driver is hesitation and frequent lane changes, as this behavior may indicate that the driver is uncertain about their route or destination. Consistent speed and clear signaling do not necessarily indicate confusion, as some drivers may intentionally maintain a certain speed or use their signals accurately. While the presence or absence of luggage can be a factor in determining a driver's level of preparedness, it is not the most significant indicator of confusion on the road.
