When driving on inter-urban roads...
This distance helps prevent collisions and facilitates safe overtaking at higher speeds.
If you are following another vehicle and it brakes suddenly...
This emergency distance gives you enough reaction time to avoid a rear-end collision.
When you are driving a vehicle over 10 meters long or over 3500 kg in weight...
Heavier and longer vehicles require more braking distance and visibility.
If road or weather conditions are poor (e.g., rain, fog, ice)...
Slippery or low-visibility conditions lengthen stopping distances and reduce reaction time.
When driving behind a motorcycle, bicycle, or other vulnerable user...
These users are more at risk, and sudden movements are more likely.
If traffic is dense or stop-and-go...
Even at low speeds, rear-end collisions can occur if you follow too closely.
