What action must a driver take when an unaccompanied child or blind person with a cane is walking on the road?

Answer: D — Come to a complete stop

When an unaccompanied child or a blind person with a cane is present on the road, the safest and most responsible action for a driver is to come to a complete stop. This ensures that the vulnerable individuals have the time and space they need to navigate safely across the road. Stopping allows the driver to assess the situation and react appropriately, prioritizing the safety of pedestrians, particularly those who may not be fully aware of their surroundings. By coming to a complete stop, drivers not only reduce the risk of accidents but also demonstrate a commitment to road safety and the well-being of all road users, including those who might be less capable of ensuring their own safety due to age or disability.
