In Norwegian road safety and vehicle operation, why must many electric vehicles (EVs) not be towed with their driven wheels rolling on the road during a breakdown?
Answer and explanation
Correct answer: C. Spinning motor acts as generator, risking inverter fire
- Step 1: Permanent magnet synchronous EV motors generate electric current when rotated; towing on driven wheels can overload the power inverter and damage electrical components unless transported on a flatbed. Answer: Spinning motor acts as generator, risking inverter fire. Why not the others: the alternative options do not accurately reflect vehicle safety standards, statutory requirements, or physical mechanics under Norwegian road regulations.
