There are two main reasons for steering wheel vibration when braking at high speeds of 120 km/h. Below are the relevant explanations: 1. Uneven brake disc wear: When brake discs wear unevenly, steering wheel vibration may occur during high-speed braking. When the vehicle reaches a certain speed and brakes, the left and right wheels on the same axle may experience asynchronous braking force moments within a rotation cycle, creating an uneven braking pattern. When this imbalance reaches a certain degree, it causes unequal rolling speeds between the left and right wheels, resulting in lateral wheel oscillation that transmits to the steering wheel. 2. Drivetrain malfunction: Steering wheel vibration during high-speed braking could also indicate issues with the vehicle's drivetrain. In such cases, it's advisable to inspect components like the tie rods and ball joints for signs of corrosion or looseness.

What to Do If You Fail the Driver's License Test 5 Times?

Here are the solutions for failing the driver's license test 5 times: 1. There is no limit on scheduling the Subject 4 test, so you can continue taking it even after failing five times. 2. For the driver's license test, the number of scheduled attempts for Subject 2 (Parking) and Subject 3 (Road Driving Skills) cannot exceed five. If you fail the fifth attempt, all previously passed subjects will be invalidated, and you will need to restart from Subject 1. 3. Each subject in the driver's license test allows one initial attempt and one retake if failed. If you do not take the retake or fail it again, the current test session ends, and you must reschedule. However, for Subject 2 and Subject 3, rescheduling must be done at least ten days later.

What grade of gasoline should a Cadillac XTS use?

Cadillac XTS requires 95-octane gasoline. Below are some important notes regarding gasoline usage for the Cadillac XTS: Avoid prolonged idling or low-speed driving: When waiting by the roadside or temporarily parking, if the vehicle remains idling, the engine continues to operate, leading to a significant increase in fuel consumption. In idle or low-speed conditions, due to relatively low engine RPM, combustion within the engine cylinders may be incomplete, which can lead to carbon buildup and further increase fuel consumption. Avoid using high-viscosity engine oil: Under the same environmental conditions, using engine oils with different viscosities can result in varying fuel consumption. If a higher viscosity oil than recommended in the maintenance manual is used, the vehicle's fuel consumption may change. Regular vehicle maintenance: It is essential to strictly follow the recommendations in the vehicle's owner’s manual for regular maintenance or servicing at specified mileage intervals. If the vehicle goes too long without maintenance, the engine oil may degrade, leading to increased fuel consumption. Additionally, a clogged air filter due to dust accumulation can affect engine air intake. Furthermore, owners should regularly check their vehicle's tires to ensure the tire pressure is within the standard range. Overly worn or aged tires not only impact fuel consumption but also compromise driving safety. Maintaining the vehicle in optimal condition is crucial for achieving the lowest possible fuel consumption.

Is it better to drive with polarized or non-polarized sunglasses?

It is better to drive with polarized sunglasses. Below is an introduction to the functions of polarized and non-polarized sunglasses: 1. Regular sunglasses: They primarily reduce the intensity of glare and ultraviolet light by dimming, but since their lenses cannot filter light, they cannot completely block these harmful rays. Their main function is to lessen eye strain. 2. Polarized sunglasses: Due to their polarized nature, they can completely block glare caused by scattering, refraction, reflection, and other factors. They fully block ultraviolet rays harmful to human eyes, making it less tiring for the eyes during prolonged activities in bright light, thus providing true eye protection. Additionally, they enhance clarity and depth perception of what you see.

What to Do When 6 Points Are Deducted from a Class B Driver's License?

If 6 points are deducted from a Class B driver's license, the driver must undergo an annual review within the same year and participate in a learning session during the review. If the deduction occurs during the probationary period, the probationary period will be extended by one year. Below is an introduction to the driving point system: 1. Drivers holding licenses for large buses, tractors, urban buses, medium-sized buses, or large trucks must report to the traffic management department of the public security authority for review within thirty days after the end of each scoring cycle. However, if there are no point deductions within a scoring cycle, the review for that cycle is exempted. 2. For drivers holding licenses for large buses, tractors, urban buses, medium-sized buses, or large trucks, if 6 or more points (but less than 12) are deducted during the one-year probationary period, the probationary period is extended by one year. If another 6 or more points (but less than 12) are deducted during the extended probationary period, the driver's qualification for the probationary vehicle class will be revoked.
