What is the primary danger when driving alongside a large heavy articulated truck that is signaling to make a tight right-hand turn at an urban intersection?

1. The truck may swing out wide to the left first before turning, and the rear trailer cut-in (trajetória de corte) will crush any vehicle on its inside right flank
2. The truck will blow air into your fuel tank
3. The truck's headlights will blind you from behind
4. The truck will decrease the road surface friction
