How Many Points Are Deducted for Driving Against Traffic on a One-Way Street?

Driving against traffic on a one-way street results in a deduction of three points. One-way streets are designated for vehicles to travel in only one direction, and driving in the opposite direction is prohibited. One-way street signs include left one-way, right one-way, and straight one-way. Instances of motor vehicles driving against traffic: On roads with solid centerlines, motor vehicles must not cross into the opposite lane. This applies to roads with double solid lines or single solid lines, where crossing is prohibited under any circumstances. On roads with dashed centerlines, overtaking is allowed if it can be done safely. On roads marked with one-way signs, any motor vehicle entering in the opposite direction is considered to be driving against traffic. Regarding point deductions for driving against traffic, according to the "Scoring Standards for Road Traffic Safety Violations," motor vehicle drivers committing any of the following violations will be penalized with a 3-point deduction: 1. Driving a passenger vehicle (excluding buses) or school bus with more passengers than the approved capacity, but less than 20% over the limit. 2. Driving medium-sized or larger passenger or cargo vehicles, or hazardous material transport vehicles on roads other than highways or urban expressways, or driving other motor vehicles at speeds exceeding the limit by less than 20%. 3. Driving a truck with cargo exceeding the approved weight by less than 30%. 4. Driving a motor vehicle on a highway below the minimum speed limit. 5. Driving a motor vehicle prohibited from entering a highway onto a highway. 6. Driving a motor vehicle on a highway or urban expressway without using the designated lane. 7. Driving a motor vehicle through a crosswalk without slowing down, stopping, or yielding to pedestrians as required. 8. Driving a motor vehicle in violation of prohibitory signs or markings. 9. Driving a motor vehicle without properly overtaking or yielding, or driving against traffic.

Should I shift to N or P gear when waiting at a red light with an automatic transmission?

When waiting at a red light with an automatic transmission, you should shift to N gear. The reason is: the P gear in an automatic transmission vehicle is the parking gear, used for long-term parking, while the N gear is the neutral gear, used when the car is temporarily stopped and not moving. Automatic transmission refers to not requiring the driver to manually shift gears; the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions. The correct method for parking an automatic transmission vehicle is: 1. Press the foot brake to stop the car; 2. Shift the gear from D to N; 3. Pull the handbrake and turn off the engine; 4. Release the foot brake without turning off the power; 5. Press the foot brake again and shift the gear from N to P; 6. Release the foot brake and turn the key back; 7. Turn off the power and remove the key.

How to Check if the Battery is Leaking?

To check if the battery is leaking, follow these steps: 1. Turn off the car's ignition switch and wait for about 5 to 10 minutes with the car locked, allowing it to enter a dormant state; 2. Loosen the fastening nut on the negative terminal of the battery, use a screwdriver to pry open the fastening block, and remove the negative connector; 3. Set the multimeter to the DC 10A or 20A range, connect the red probe of the multimeter to the car body ground wire, and the black probe to the negative terminal of the battery; 4. Observe the reading on the multimeter. The battery is a type of cell, also known as a storage battery, which works by converting chemical energy into electrical energy.

What Does the Engine Symbol on the Dashboard Mean?

When the engine symbol appears on the dashboard, it indicates that the ignition switch is turned on, the control indicator light is illuminated, and it should turn off shortly after the engine starts. An engine is a machine that converts one form of energy into another, typically transforming chemical energy into mechanical energy. The reasons for the engine yellow light appearing on the dashboard include: 1. A clogged car air filter causing restricted airflow; 2. Faulty spark plugs, ignition coils, fuel pump, or blocked fuel lines leading to poor combustion of the engine's air-fuel mixture; 3. Improper maintenance increasing the engine's operational burden; 4. Poor fuel quality resulting in increased carbon deposits inside the engine cylinders.

When is it appropriate to use high beams?

High beams can be used in the following situations: 1. Roads with no street lighting or poor illumination; 2. When overtaking another vehicle; 3. When navigating corners or curves; 4. When driving in conditions of low visibility such as fog, rain, snow, dust, or hail; 5. When needing to read road signs. The method to activate high beams is to push the light control lever outward. Their purpose is to enhance visibility and expand the field of view. Vehicle lights and their functions can be categorized as: 1. Headlights: Illuminate the road and objects ahead to ensure driving safety; 2. Width indicators: Show the vehicle's width to alert oncoming and following vehicles; 3. Fog lights: Make the vehicle more noticeable to oncoming and following traffic; 4. Turn signals: Alert nearby vehicles and pedestrians.

What should be noted after replacing brake pads?

After replacing brake pads, the following precautions should be taken: 1. Press the brake pedal several times to eliminate the gap between the shoe and the brake disc; 2. Check the brake fluid; 3. Use a special tool to push the brake caliper piston back. Brake pads are composed of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and during the coating process, an SMT4 furnace temperature tracker is used to monitor the temperature distribution to ensure quality. Situations that require brake pad replacement include: 1. When the thickness reaches about 0.3 cm; 2. When the brake warning light is on; 3. When a hissing sound occurs during braking; 4. When the braking effect is significantly weakened.
