628.1. The Minister may, for the period the Minister determines, enter into an agreement with any municipality to exempt it from the requirement to submit to the Minister, as the case may be, a by-law, resolution or ordinance made pursuant to section 627 regarding speed. The agreement must specify which public highways are maintained by the municipality and establish the conditions and procedures for establishing a speed limit other than that provided for in this Code. In addition, the agreement must specify the conditions for the consultation of other municipalities concerned.
This section shall not operate to prohibit the Minister from disallowing any by-law, resolution or ordinance respecting speed, made under an agreement referred to in this section, if such by-law, resolution or ordinance may endanger the safety or impair the mobility of persons or goods. The Minister may remove, where expedient, any sign or signal the Minister considers inappropriate where the municipality does not remove it within the time indicated by the Minister.
