How traffic ticket fines are calculated
The price tag on a traffic ticket is almost never what it appears. Every state sets its own base fine schedule — the starting point before any additional fees are applied. But in most states, mandatory surcharges, court fees, and administrative assessments can multiply that base fine by two to five times.
California is the most dramatic example. A speeding ticket for 1–15 mph over carries a $35 base fine, but California's 9–12 mandatory add-ons — including a state penalty assessment ($26), a county penalty assessment ($7), a court operations assessment ($40), a DNA identification fund fee ($4), and others — bring the typical total to $230 or more. That's a 6x multiplier over the base fine.
Other states are far more straightforward. In Iowa or North Dakota, the fine you see on the ticket is essentially what you pay, with minimal court costs. Understanding this distinction is why many drivers are shocked when they receive the actual court notice — the number on the ticket is not the number to bring to the courthouse.
