You're Responsible for Your Own Driving Capacity
The law puts the burden on you as the driver. If you're too stressed, too upset, too distracted or too overconfident — you should not drive. Knowing the rules by heart isn't enough if you lose the ability to apply them. During the 2-year probation that follows your first licence, even minor violations can revoke it. Revocation means redoing both the practical and theory tests from scratch.
