  2. B
    By positioning the vehicle close enough to read the rear license plate clearly
  3. C
    By relying on the truck driver to spot your vehicle in their interior center rearview mirror
  4. D
    By matching the truck's speed while driving directly centered behind the trailer

Answer

By ensuring both of the truck's side mirrors are visible from the driver's seat
Large commercial trucks have large blind spots directly behind them known as rear No-Zones. A reliable safety rule of thumb is that if you can see both of the truck's side-view mirrors, the truck driver can see your vehicle.

Step-by-Step Solution

1
Identify how commercial truck drivers view traffic behind their vehicle
Large tractor-trailers rely entirely on wide side-view mirrors because the cargo trailer blocks direct rearward visibility.
Understanding driver sightlines helps determine where blind spots are located.
2
Apply the sightline rule of thumb for rear No-Zones
If you can see the truck's side-view mirrors, the truck driver can see your vehicle in those mirrors.
This simple visual check confirms that your vehicle is at a safe distance outside the rear blind spot.
