377. Where a municipality fixes by by-law a speed limit different from that prescribed in section 373, it must clearly indicate the different limit on traffic control devices, failing which section 373 applies.
A municipality that has not availed itself of the first paragraph shall, at the approaches to a built-up area in its territory, on a public highway or part of a public highway under its maintenance, have traffic control devices installed, indicating that the speed limit is 50 km/h.
