Why the penalty scales with how far over you were
The faster a vehicle is going beyond the posted limit, the longer it takes to stop and the more force is involved in any collision, so the potential harm rises sharply with speed. Tiered fines are built to reflect that β a small excess carries a modest penalty, while a large one is treated close to a serious safety violation.
The margin for error is not a target to aim for
Even where cameras carry a built-in tolerance, that margin exists purely to absorb measurement uncertainty in the equipment, not to give drivers a few extra km/h or mph of leeway. Treat the posted limit as the actual limit, and any tolerance as a safety net you never intend to use.
Frequently Asked Questions
Can I get ticketed for going just 1-2 km/h (or mph) over?
It's possible, though many systems build in a small tolerance for measurement error. Rather than relying on that margin, the safest approach is simply to stay at or under the posted limit from the start.
If I pay a camera fine, does that mean no points at all?
In many systems, yes β a fine billed to a vehicle's registered owner through automated enforcement often carries no points, while a ticket issued to an identified driver in person typically does. This varies by jurisdiction, so it's worth checking the specific rules where you drive.
