What Causes the Exclamation Mark to Appear on the Car Dashboard?

Why can't the newly replaced driver's license be registered on 12123?

The newly replaced driver's license cannot be registered on 12123 because there is a delay in system information updates. The vehicle management office's database has not been synchronized and updated in time, making it impossible to check online. You need to wait until the system data synchronization is completed before you can view it. It may also be because the correct issuing address of the driver's license was not selected during registration, causing some data to not display or be delayed. You need to select the driver's license transfer and transfer it to the issuing address of the driver's license for it to be displayed. Below is additional information: 1.

What does 84t on a tire mean?

84t on a tire refers to the tire's load index and speed rating. The number 84 indicates that each tire can bear a maximum weight of 500kg, while the letter t signifies that the tire can withstand speeds of up to 190 kilometers per hour. The functions of tires include: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting the vehicle's load; 3. Reducing and absorbing vibrations and impacts during driving to prevent severe vibrations from damaging vehicle components. As one of the crucial components of a vehicle, tires directly contact the road surface and work in conjunction with the vehicle's suspension to mitigate shocks during driving. This ensures good ride comfort and smooth driving, maintains excellent adhesion between the wheels and the road surface, enhances the vehicle's traction, braking, and off-road capabilities, and supports the vehicle's weight.
