A safe speed to drive your car:

  1. Is the posted speed limit
  2. Is less than the posted speed limit
  3. Depends on the weather and road conditions ✓
  4. Depends on the mechanical skill of the driver

Answer: C. Depends on the weather and road conditions

A safe speed depends on the weather and road conditions.

Why this is the answer

The manual treats weather and other special conditions as hazards that change how you drive. It says bad weather can be a problem and that in rain, fog, or snow you should reduce your speed. It also says special conditions or hazards make attention and judgment more important. So the right speed is not a fixed number; it is the speed that fits what is happening around you.

Why the other answers are wrong

Remember it

Before you pick a speed, ask what the weather and road are doing.
