In the field checking of large transportation vehicles permission, the problems of false declaration of vehicle owners, inconsistent large and small certificates, inconsistent vehicle certificates and the like occur, the large transportation market order is disturbed, the transportation carrier environment is deteriorated, highway facilities are damaged, and even major public safety accidents are caused. On the one hand, some truck owners and drivers innocently indicate that the weighing and approval procedures are not intended, but suffer from the failure to transact the weighing and approval procedures according to the normal procedures; on the one hand, the method also promotes high return brought by certain carriers for pursuing illegal transportation, is in danger, continuously challenges traffic law enforcement authorities, has great hidden dangers for traffic transportation safety production, road construction maintenance and people property protection, and has very little effect if being carried by management means such as oral propaganda and education to drivers.
