Is it acceptable to not move the steering wheel while driving straight?

[DelRebecca]

It is acceptable to not move the steering wheel while driving straight. Here is relevant information: 1. Throttle control: Flexible throttle control is required during straight-line driving to avoid sudden speed changes that may affect normal operation. Inconsistent speed control may also cause steering deviation. 2. Posture adjustment: Incorrect sitting posture may affect visual judgment. For trainees with poor vehicle sensitivity, deviation is likely to occur. During straight-line driving, it's necessary to look farther ahead - from the road center in front of the cab to the distant view - and make timely adjustments when detecting vehicle deviation.
