Questão jurídica principal
Whether a second light traffic offense during the probationary period triggers caducity of a probationary driving licence under Art. 15a para. 4 LCR.
Decisão extraída
Yes. A second offense that would entail a withdrawal under Art. 16a para. 2 LCR is sufficient, even if the offense is only light.
Fundamentação extraída
The wording, purpose, and case law show that caducity depends on the existence of a first withdrawal-triggering offense and a second offense also leading to withdrawal; the gravity of the second offense is not decisive.
