The State of Yucatán has done a very wise thing by merging the wearing of masks with the operation of motor vehicles. This act allows for enforcement by traffic cops. All drivers must wear a mask while operating a vehicle. Men, especially, are widely known to resist wearing masks. But how many would risk a traffic infraction for the “liberty” of not wearing one? — the liberty to infect others. Yucatecos should be proud of this law. It is one of the wiser policies enacted anywhere. (eg: The effectiveness of wearing masks is established as reasonable for reducing the spread of cv-19.)
