Tips for the fourth subject of the small car driving test are as follows: Light usage: Turning on the high beam is always wrong, turning on the hazard warning flashers is always correct, turn on the left turn signal when entering the highway, turn on the right turn signal when exiting the highway, "do not turn on any signal when entering a roundabout, turn on the right turn signal when exiting a roundabout". Wheels: If the front wheels skid, turn the steering wheel in the opposite direction; if the rear wheels skid, turn the steering wheel in the same direction. In summary, it's opposite for the front and same for the rear. If the question does not specify front or rear wheels, assume it's the rear wheels skidding. ABS anti-lock braking system: It maintains steering capability, and you can press the brake pedal firmly. Emergency braking while steering may cause skidding. The braking distance will not be shortened or lengthened. For vehicles without ABS, press the brake pedal lightly or intermittently. If there is a problem with the power steering system, you cannot continue driving and need to stop to check the cause.
