Is it possible to give a warning signal by hand when driving along this path?
Allowed if the turn signal indicator is defective.✓Richtige Antwort
Allowed if the turn signal indicator is defective, during daylight hours.
Allowed in all cases.
Erklärung
The driver's outstretched arm can replace the electrical direction indicator when that indicator is defective, provided the gesture is clear to other road users. The rule is based on failure of the fitted signal, not on a daylight-only exception, so daylight is not an additional condition.
