  2. have your hand near your horn
  3. drive below the speed limit
  4. take your right of way

Answer: A. leave plenty of room to stop or steer around vehicles

The best preparation is to leave plenty of room to stop or steer around vehicles.

Why this is the answer

The handbook's sharing-the-road section says that keeping well away from other road users lowers the chance of space conflicts. It explains that this space gives you room to stop or steer around when someone else starts moving into the space you are using. That matches leaving plenty of room to stop or steer around vehicles. The other choices do not create that buffer, and the passage points to space margins rather than horn readiness, slower speeds, or claiming right of way.

Why the other answers are wrong

Remember it

Think buffer first: space around your car gives you somewhere to go when someone else surprises you.
