When overtaking another vehicle with a long articulated truck on a two-lane national road, why does the maneuver require significantly more time and distance than with a passenger car?

1. The truck's greater length (up to 15.50 m articulated, 18 m as a road train), lower power-to-weight ratio and slower acceleration require hundreds of metres of clear oncoming roadway
2. Heavy trucks are legally required to stop in the oncoming lane before completing an overtake
3. The truck's speed limiter automatically shuts down the engine during overtaking
4. Overtaking with a heavy truck requires permission via satellite radio
