Recently, the frequent accidents of vehicle tire blowouts caused by brake pad fragments left on the road surface due to crushing on highways have attracted high attention from traffic police departments. According to the traffic police department, these brake pad fragments often come from the worn and detached parts of the front vehicle's brake system. Once crushed by the rear vehicle, they can easily cause tire damage or even blowouts. Therefore, the traffic police department reminds drivers to conduct a comprehensive inspection of their vehicles before driving at high speeds to ensure that key components such as tires and brake systems are in good condition; During driving, if foreign objects or suspected brake pad fragments are found on the road surface, they should be avoided in a timely manner and reported to the police for handling.
