Should the penalty for traffic violations depend on the driver’s income?

In some countries, traffic fines are adjusted based on the offender’s income - a system known as "day fines" - to ensure that penalties are equally impactful regardless of wealth. This approach aims to create fairness by making fines proportionate to the driver’s ability to pay, rather than applying the same flat rate to everyone. Proponents argue that income-based fines make penalties more equitable, as flat fines may be insignificant to the wealthy but burdensome to low-income individuals. Opponents argue that penalties should be consistent for all drivers to maintain fairness under the law, and that income-based fines could create resentment or be difficult to enforce.
