How can you avoid the risk of the rear wheels dropping off the pavement when going around a right curve?
- Keep the front wheels close to the left side of the lane ✓
- Weave back and forth within your lane
- Move into the left lane
- Keep the front wheels close to the right side of the lane
Answer: A. Keep the front wheels close to the left side of the lane
Keep the front wheels near the left edge of your lane when going around a right curve.
Why this is the answer
The handbook explains that rear wheels do not steer with the front wheels and follow a tighter path, so a truck cuts inside a curve. On a right-hand curve, you lead the turn by holding the front wheels toward the left side of your lane. That leaves room for the rear wheels to stay on the pavement instead of dropping off the right edge. This is why the answer about the left side of the lane fits the handbook.
Why the other answers are wrong
- B. Weave back and forth within your lane — Weaving back and forth within your lane does not account for the rear wheels' tighter path and is not the handbook's method for a right curve.
- C. Move into the left lane — Moving into the left lane is not the guidance; the handbook says if possible do not change lanes to turn, and you should stay in your lane while leading the arc.
- D. Keep the front wheels close to the right side of the lane — Keeping the front wheels near the right side suits a left curve to stop the rear crossing into the other lane, not a right curve where the rear can drop off the pavement.
Remember it
Think 'right curve, left lead' because the rear wheels follow a tighter path.
