What is the consequence for a learner driver not displaying the appropriate 'L' plates?

The correct consequence for a learner driver not displaying the appropriate 'L' plates is 2 penalty points added to their driving record. In Ireland, it is a legal requirement for learner drivers to display 'L' plates prominently when behind the wheel. This regulation helps other road users recognize that the driver is a learner and may not have extensive driving experience.

Failing to display these plates not only disregards this safety measure but also reflects non-compliance with driving regulations. The addition of penalty points serves as a deterrent to ensure that learner drivers adhere to the rules of the road. Accumulating penalty points can also lead to further consequences, such as higher insurance costs or additional penalties, depending on the driver's record.

While other answers may seem plausible, such as a warning or a fine, they do not capture the specific regulatory framework surrounding learner drivers and their requirements. Mandatory retraining is typically involved in more severe violations, but not for the failure to display 'L' plates, making penalty points the most relevant and immediate consequence.
