What is the primary danger when an oncoming small car or motorcycle attempts to squeeze past a turning heavy truck at a narrow intersection?

1. The truck's wide sweep and off-tracking rear trailer wheels can crush the smaller vehicle against the curb or road barrier
2. The truck's radio will cause the motorcycle's engine to shut down
3. The truck's headlights will instantly short-circuit
4. The small vehicle will be blown 50 metres into the air by engine exhaust
