Safety belt checkpoints are not allowed to enforce which of the following?

Safety belt checkpoints are primarily established to ensure compliance with seat belt laws. However, these checkpoints cannot be used to enforce speeding laws, driving under the influence, or checking the validity of licenses directly.

The focus of safety belt checkpoints is specifically on whether occupants of vehicles are wearing their seat belts. Consequently, while these checkpoints can result in the issuance of citations for individuals not wearing seat belts, it does not extend to enforcement of other traffic laws, such as speeding or driving under the influence, unless those infractions are discovered incidentally during the checkpoint procedure. Therefore, the nature of safety belt checkpoints restricts their enforcement capabilities primarily to seat belt compliance.

This is an important aspect of traffic law enforcement, as it protects the rights of drivers and passengers while ensuring that the primary aim of the checkpoint – to promote seat belt use – remains clear and effective.
