If a vehicle travelling ahead of you in the same direction is close, may you use the main beam?

Question image: If a vehicle travelling ahead of you in the same direction is close, may you use
  • A Yes, as long as they also have it on
  • No, it could dazzle them through their mirrors
  • C Yes, it does not affect the vehicle ahead
  • D Yes, but only on motorways

Why this is the correct answer

No. The main beam must also be switched off so as not to dazzle the driver ahead through their rear-view mirrors, not only oncoming drivers.
