Can You Drive on the Highway After Frame Repair?
2 Answers
You cannot drive on the highway after frame repair. Below are specific explanations regarding highway driving: 1. Precautions: There are two types of lanes at highway toll stations—ETC lanes and regular lanes. ETC refers to the bank card and card reader attached to the windshield. If you haven’t applied for ETC at the bank, you should take a regular lane to get a ticket. If you accidentally enter an ETC lane, you can reverse out safely, as ETC lanes have sufficient waiting distance for reversing. 2. Regulations: The majority opinion is that you should not drive on the highway during the break-in period. This is because the engine operates at high speeds, leading to maximum mechanical wear, and the first batch of oil contains the most metal shavings and impurities. Using this oil for high-speed driving significantly increases engine wear and may even cause abnormal wear. As a result, the vehicle may not be in optimal condition after the break-in period.
Can a repaired chassis be driven on highways? Over the years, I've seen many cases, and the key factor is the quality of the repair. If it's just a simple weld with misaligned structure or the use of substandard materials, the chassis is prone to deformation and cracking again due to high-speed vibrations, which is extremely dangerous. Especially on highways, where the vehicle speed is extremely high and the body is under tremendous pressure, structural weaknesses can be exposed during emergency braking or lane changes, leading to loss of control and accidents. It's recommended to have a comprehensive inspection by a professional organization after the repair, such as using laser scanning to check weld points and frame straightness, and conducting dynamic balance tests to assess driving stability. During test drives, start with low speeds in urban areas and gradually increase speed to check for abnormal noises or vibrations. Safety first—don't rush into long-distance highway driving until all details are confirmed to be correct.
