[DeMarcus]

For the S-curve in Category 2 of the Large Passenger Vehicle A1 license test, there are key points to observe before entering and after entering the curve. Before entering: Before entering the S-curve, position the vehicle slightly towards the outer side of the road. When entering, look straight ahead and align the vehicle with the center of the road (in practice, it's better for the vehicle body to enter slightly angled along the midline of the S-curve). Once the vehicle enters the S-curve, look down from the left front corner of the vehicle. When the left front corner of the vehicle aligns with the right edge line of the S-curve, turn the steering wheel one full turn to the left, then slowly continue turning left while watching the left front corner of the vehicle. After entering the curve: Enter the S-curve in 1st or 2nd gear, keeping the vehicle about 0.5m away from the right side of the road. Maintain the left wheels of the vehicle about 0.5m from the edge line of the road, making moderate directional adjustments. When driving into the curve, reduce speed in advance and keep to the right.
