Will traffic police check vehicles on highways?

[Daryl]

Traffic police do not check vehicles on highways, but they may set up checkpoints at toll stations and ramp entrances. Relevant regulations: The "Road Traffic Safety Law" has strict regulations on traffic police enforcement on highways. Except for emergency duties, traffic police are not allowed to intercept and inspect vehicles on highways. On highways, sudden braking due to high speeds may cause traffic accidents, so traffic police cannot check vehicles on highways. If it is necessary to intercept and inspect vehicles on highways due to "emergency duties," checkpoints should be set up at toll stations or ramp entrances, with conspicuous temporary inspection signs set up in advance to inform drivers ahead to slow down and avoid accidents. Legal basis: Article 69 of the "Road Traffic Safety Law of the People's Republic of China": No unit or individual may intercept and inspect moving vehicles on highways, except for public security officers performing emergency official duties in accordance with the law.
