Can traffic police stop vehicles on highways?

[MacGiselle]

Traffic police do not stop vehicles on highways. However, they may set up checkpoints at toll stations, ramp entrances, and other locations. Here is the relevant information: 1. Where highway traffic police can conduct checks: Highway traffic police can patrol the roads or set up checkpoints at highway entrances, exits, and toll stations. 2. Relevant laws: Article 69 of the Road Traffic Safety Law of the People's Republic of China stipulates: No unit or individual may intercept or inspect moving vehicles on highways, except for public security officers performing urgent official duties in accordance with the law. 3. Reasons why vehicles cannot be stopped on highways: On highways, sudden braking due to high speeds can cause traffic accidents. Therefore, traffic police cannot stop vehicles on highways. If vehicles must be intercepted and inspected due to "urgent duties," checkpoints should be set up at toll stations, ramp entrances, etc., with prominent temporary inspection signs displayed in advance to inform drivers ahead to slow down and avoid accidents.
