What is the recommended minimum passing distance when overtaking a cyclist in speed zones over 50 km/h?

In speed zones over 50 km/h, the recommended minimum passing distance when overtaking a cyclist is 1.5 metres. This distance is crucial for ensuring the safety of cyclists as they are more vulnerable road users. When a vehicle passes a cyclist with adequate clearance, it significantly reduces the risk of collisions and provides a buffer zone that accounts for factors such as wind turbulence from the vehicle, the cyclist’s balance, and any sudden movements that might occur.

The rationale behind this specific distance of 1.5 metres is to create enough space so that even if the cyclist swerves slightly or if the vehicle drifts, there is still a safe gap preventing contact. Given higher speeds, the margin for error diminishes, making it even more critical to maintain this passing distance.
