Driving at a speed considerably slower than the flow of traffic can frustrate other drivers. This may lead them to attempt risky passing maneuvers, increasing the potential for collisions.

The posted speed limit indicates the maximum speed for ideal conditions. Drivers must reduce their speed below this limit when conditions are poor, such as during rain, snow, or fog, to maintain safety.

Within urban areas, the default speed limit is 50 km/h unless otherwise posted. Drivers must adhere to this limit to ensure safety in densely populated and high-traffic environments.
