What is the speed requirement for straight-line driving?

[McGarrett]

Straight-line driving requires a speed of no less than 30km/h and no more than 40km/h, with the optimal speed controlled at 36km. The following are relevant details: 1. Steering wheel issue in straight-line driving: Straight-line driving means maintaining the vehicle's straight-line movement, not keeping the steering wheel motionless. However, there are techniques for operating the steering wheel. Generally, the right hand performs actions like acceleration and gear shifting, making it especially important for the left hand to hold and stabilize the steering wheel. Additionally, slight adjustments can be made to the steering wheel during driving, but sudden and forceful movements should be avoided. 2. Vision issue in straight-line driving: Adhere to the principle of "looking far while taking care of the near." This means looking ahead to spot situations early and react in advance, while also paying attention to the immediate surroundings and the rear of the vehicle. Since the speed in the third section of the driving test is fast, looking far ahead helps in early detection of situations and making preemptive responses. At the same time, the vehicle is more likely to maintain a straight path.
