Final answer:
To help a truck or bus driver see you and avoid blind spots, stay to the side where you are visible in the side mirrors, and avoid lingering directly in front or behind these large vehicles.
Step-by-step explanation:
To avoid being in a truck or bus driver's blind spot and help them see, the safest option is 3) Stay to the side of the truck or bus where you can be seen. Large vehicles such as trucks and buses have significant blind spots, often referred to as "No-Zones," which are areas around the vehicles where your car is not visible to the driver.
To remain visible, it's important not to linger alongside a truck or bus and instead either stay ahead of the vehicle where you can be seen through the driver's side mirror, or safely behind it at a distance that allows the driver to see you in their side mirrors. Never stay directly in front or right behind large vehicles because these are areas where the driver has limited or no visibility.
Additionally, when passing, do so quickly and safely to minimize the time spent in the blind spot. Always signal your intentions early and ensure you can see the driver in their side mirror before making any moves around their vehicle.
