What is the maximum speed limit in residential areas in Alberta?

Answer: B — 50 km/h unless otherwise posted

In Alberta, the maximum speed limit in residential areas is set at 50 km/h unless otherwise posted. This regulation is designed to enhance safety in neighborhoods where children, pedestrians, and cyclists are likely to be present. The 50 km/h speed limit encourages drivers to maintain a pace that allows for quick reaction times in case of unexpected events, such as a child running into the street or a cyclist emerging from a driveway. While the other speeds listed could theoretically apply in different contexts or locations, they are not the standard limit for residential areas. Thus, the 50 km/h limit provides a clear and established guideline that helps ensure the safety of all road users in these typically more populated settings.
