How many points will be deducted for overloading a small car?

A regular 5-seater sedan, if overloaded by one person, will be penalized with 6 points at once. Here is the detailed explanation: 1. Regulations: Driving a commercial passenger vehicle with more than 20% over the approved number of passengers will result in 12 points deducted at once. Driving a commercial passenger vehicle with less than 20% over the approved number of passengers, or driving other passenger vehicles with more than 20% over the approved number of passengers, will result in 6 points deducted at once. Driving passenger vehicles other than commercial passenger vehicles or school buses with less than 20% over the approved number of passengers will result in 3 points deducted at once. 2. Safety issues: A 5-seater car carrying 6 people means 20% overloading, which will be penalized. This is because the safety facilities in the car are only designed for 5 people, such as airbags. When you hold a baby in your arms, the airbag may not deploy or may not function at all, increasing the risk of casualties in the event of a traffic accident.

Why Does the Steering Wheel Shake on the Highway?

There are several reasons why the steering wheel shakes when driving at high speeds: 1. Overheating of the brake discs or brake pads, which deform when cooled, causing the steering wheel to shake. This can occur due to excessive braking frequency or overly aggressive braking. It typically manifests as sudden shaking during high-speed driving. Solution: Replace the brake discs or brake pads. 2. Issues with the drivetrain. This usually appears as steering wheel shaking at speeds between 80 km/h and 90 km/h, with normal operation resuming above 90 km/h. Solution: Lift the front axle and test the wheels. If misaligned, adjust them. If the tires are severely deformed, replace them. 3. Inconsistent tire pressure or abnormal tire pressure among the four tires. Solution: Identify the cause and replace the tires if necessary. 4. Problems with wheel alignment. The most common issue is changes in alignment parameters such as toe angle, camber angle, kingpin inclination angle, and caster angle. Solution: Perform a four-wheel alignment. 5. Disrupted wheel balance. Changes in tire weight distribution, such as uneven tire wear or wheel hub deformation, can disrupt wheel balance. Solution: Rebalance the wheels.

The black wire needs to be connected to the ground wire, the white wire to the low beam wire, and the blue wire to the high beam wire; 3. If the ground wire is not connected, the bulb will not light up, so it is essential to follow the correct sequence when installing the bulb. Additional Information: 1. There are two types of H4 bulbs: the first is 12V 65/55 watts, and the second is 24V 75/70 watts. Ordinary small vehicles use the first type.
