To avoid being in a truck or bus driver’s blind spot, you should:

  1. Never pass them.
  2. Avoid driving alongside them and avoid tailgating. ✓
  3. Flash your lights at them.
  4. Sound your horn.

Answer: B. Avoid driving alongside them and avoid tailgating.

Avoid driving alongside a truck or bus and avoid tailgating it.

Why this is the answer

The Texas handbook says to stay out of a truck's rear blind spot and not follow too closely. It tells you to place your car where the truck driver can see it in the side view mirror. That same mirror guidance is why you should not sit alongside a truck or bus in an area the driver cannot see. Keeping clear of those spaces and leaving following distance keeps you visible and gives you room to react.

Why the other answers are wrong

Remember it

Use the side mirror as your check: if you cannot see the truck driver there, ease back until you can.
