Prince Edward Island has a typical maximum speed limit of 90 km/h on all provinical highways. This limit applies to major routes such as the Trans-Canada Highway and is designed to support safe and efficient travel across the island.

In the absence of specific posted signs, Prince Edward Islands default speed limit in residential zones is 50 kilometers per hour. This applies unless local municipalities have enacted bylaws to reduce the limit for enhanced safety.

In Prince Edward Island, school zones typically follow a speed limit of 60 kilometers per hour. These lower limits are crucial for protecting children during active school hours and when they are entering or leaving school grounds.

Reduced speed limits in school zones usually apply specifically on weekdays during designated school hours. This timeframe, typically from 8 in the morning to 5 in the evening, aims to maximize child safety when school is in session.

Children can suddenly enter the road without warning near schools, often without looking for traffic. Reduced speed improves a drivers reaction time and significantly lowers the chance of a serious collision, protecting vulnerable pedestrians.

Drivers are legally required to reduce their speed when road or weather conditions are poor, such as during rain, snow, or fog. Simply following the posted limits is insufficient if visibility or traction is adversely affected.

The default speed limit in most built-up areas within municipalities is 50 kilometers per hour. While this is the general rule, municipalities retain the authority to lower this limit in specific zones like school areas or residential neighborhoods.

This limit helps maintain safe speeds on rural and secondary highways, balancing travel efficiency with safety.

These roads are built for higher traffic volumes and better visibility, allowing for slightly faster yet controlled travel.

Lower urban speed limits reduce the risk of injury to pedestrians, especially near homes, schools, and parks.
