BDifficulty 2/5

On a motorway, very dense fog requires reducing speed below 60 km/h to drive safely. May you do so?

Correct answer

Yes, when those conditions require it for safety.

Yes. Road conditions can justify driving below the minimum speed when necessary for safety. Adapt speed so you can stop within the visible distance; do not maintain 60 km/h if unsafe. The exception does not depend on other vehicles being ahead.
