The 'LOCK' position is the switch to immobilize the vehicle. When the car key is turned to this position, it locks the steering wheel, preventing significant movement. 'AUTO' represents automatic four-wheel drive. In automatic mode, the system will automatically adjust whether to engage the front drive, while the 'LOCK' position disables the front-wheel drive mode.

To use the four-wheel drive hub lock, first park the vehicle, shift into neutral, and engage the parking brake, then exit the vehicle to operate. Manually turn the knob at the center of each front wheel from the FREE position to the LOCK position. This action effectively creates a rigid connection between the front wheel hub and the axle, preventing power loss during off-road slippage. After locking, get back in the vehicle, engage low-range four-wheel drive, and you can tackle steep climbs or mud pits. Once you've cleared the obstacle, remember to park, disengage four-wheel drive mode, and then exit the vehicle to turn the knobs back to the FREE position. A quick note: some older models may produce slight metallic clanking sounds after locking, which is normal. Never attempt to turn the knobs while driving to save time—this can cause gear teeth to clash and fail. Regularly spray some WD-40 into the knobs to prevent rust, especially after driving through mud or water.

Can points still be deducted after the driver's license has already accumulated 12 points?

You cannot drive after accumulating 12 points. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," if a motor vehicle driver accumulates 12 points within a scoring cycle, the driver's license will be confiscated by the traffic management department of the public security authority. Driving while the license is confiscated is considered unlicensed driving, and if caught, you will be fined. How to handle a driver's license with 12 points: The motor vehicle driver must report to the traffic management department of the public security authority in the jurisdiction where the driver's license was issued or where the violation occurred within 15 days to attend a seven-day study session on road traffic safety laws, regulations, and related knowledge. After passing the exam, the points will be cleared, and the driver's license will be returned. How to handle an expired driver's license: If the driver's license has not been reviewed for over one year but less than two years, you must retake the subject one exam and pass it to renew the license. If the license has not been reviewed for over two years, you must return to driving school, retake all three subject exams, and obtain a new driver's license.

How Many Points Lead to Driver's License Revocation?

Revocation of the "Driver's License" is not related to the number of points deducted. Individuals who are penalized for driving under the influence of alcohol and then drive under the influence again will face detention of up to ten days, a fine, and revocation of their "Motor Vehicle Driver's License". Those who drive under the influence of alcohol to the point of intoxication will be restrained by the traffic management department of the public security authorities until sober, have their "Motor Vehicle Driver's License" revoked, and be held criminally liable; they will not be allowed to re-obtain a "Motor Vehicle Driver's License" for five years. Driver's License Point Accumulation Cycle: The driver's license point accumulation cycle is 12 months, with a full score of 12 points, calculated from the date of initial issuance of the motor vehicle driver's license. Points deducted from the driver's license are categorized based on the severity of traffic violations, with five levels of point deductions: 12 points, 6 points, 3 points, 2 points, and 1 point. Reasons for Driver's License Revocation: Revocation refers to the situation where, after legally obtaining a driver's license, statutory reasons lead to its revocation by law. For example, those who bear more than half the responsibility in major traffic accidents should have their driver's license revoked according to regulations. These are all administrative actions.

Can I drive if I left my driver's license at home?

If you frequently drive outside, you need to carry your driver's license and vehicle registration. Occasionally forgetting it once is acceptable. If checked on the road, you can provide your ID number for online verification, but this should not be a regular occurrence. If it happens frequently, it will be treated as driving without a license, leading to detention, fines, and point deductions. Validity period of driving school enrollment: It starts from the date of passing the subject one test. After completing the subject one test, you must pass the subject two and subject three tests within three years. If you fail to do so, all passed subjects will become invalid, and you will need to re-enroll for the subject one test. Driver's license classification: Driver's licenses are divided into 16 categories: A1, A2, A3, B1, B2, C1, C2, C3, C4, C5, D, E, F, M, N, P.
