How many centimeters is the maximum allowable deviation for straight-line driving?

[JadeAnn]

Straight-line driving should not deviate more than 30 centimeters to either side. The assessment requirements for straight-line driving are as follows: Requirement 1: The driver must start smoothly and maintain a basic sequence of driving operations. Requirement 2: The driver must correctly handle the steering wheel (primarily using the left hand) and utilize the steering wheel's free play to adjust the driving direction. Requirement 3: The driver must master the timing and methods of gear shifting, being adept at switching between high and low gears at various speeds (including sequential upshifting, sequential downshifting, or skip downshifting). Requirement 4: The driver must be capable of timely and effective use of the brake (anticipatory braking for deceleration).
