If the fine amount you remember from a few years ago feels wrong, that's because it probably is — the Road Transport Act meaningfully raised penalties for a range of common violations compared to the ordinance it replaced.
Fines generally scale with the severity and repeat nature of the violation — a first-time paperwork lapse is treated very differently from a violation involving injury or repeat offenses. Documentation issues (license, registration, fitness certificate) sit at the lower end; reckless driving and violations causing harm sit at the much higher end, and can carry non-monetary consequences too.
One detail people are frequently surprised by: some violations attach to the vehicle's registered owner, not just whoever was driving at the time — relevant if you lend your car or ride a family member's motorcycle.
This guide is a general orientation, not a citation of the exact current fine schedule — amounts are adjusted periodically, so treat any specific number you hear as something to verify before you rely on it.
