How many days can a new car go without temporary license plates?

[AngelinaDella]

Temporary license plates are generally valid for no more than thirty days, and new cars should not use temporary plates for more than 15 days. Here are some relevant precautions for using a new car: 1. Avoid overloading: Carrying too much weight in a new car during the break-in period can damage the mechanical components. Since the power transmission parts of a new car have not yet fully broken in, aggressive acceleration can cause irreversible damage to the vehicle. Therefore, during the break-in period, it is essential to follow the principle of "slow is better than fast." 2. Speed limits for new cars: Domestic cars generally have a speed limit of 40~70 km/h, while imported cars usually have a limit of 100 km/h. When the throttle is fully open, the speed should not exceed 80% of the maximum speed. The engine speed during the break-in period is recommended to be between 2000~4000 rpm.
