How many degrees can the steering wheel not exceed when driving straight?

[HarperMarie]

When driving straight, the steering wheel should not exceed 5 degrees. Correct operation of the steering wheel: Place both hands with appropriate force at the nine o'clock and three o'clock positions on the steering wheel. The four fingers should naturally grip firmly, and the thumbs should naturally extend along the edge of the steering wheel. Steering wheel techniques: When driving straight on a flat road, use the "correction method" to control the steering wheel. The correction method involves making minor adjustments only when the direction deviates from the driving centerline. Each adjustment should be limited to within 30 degrees to ensure smooth vehicle movement. For gentle turns, steer early and slowly, and return early and slowly. For sharp turns, steer late and quickly, and return early and quickly. Develop predictive ability by preparing your hands for the turn before it begins.
