A speed camera flashes when you exceed the limit by a certain tolerance, often 10% plus 2 mph (or km/h), but this varies by region, camera type (some use infrared and don't flash visibly), and local rules, with school zones often having zero tolerance; for example, in a 40 mph zone, it might flash around 46 mph, while in a 100 km/h zone, it could be around 112 km/h, though some areas might be stricter (e.g., 10% + 3 km/h) or have no tolerance at all in school zones.
No, driving 10 km/h under the speed limit isn't inherently illegal, but it can become an offense if it unreasonably obstructs traffic, meaning you're causing congestion or disrupting the flow, especially if you're in the wrong lane or on a fast road without good reason. There's no set minimum speed, but police can fine you under laws like Australia's Rule 125 for impeding other drivers, making the legality dependent on road conditions and your actions.
Mobile Speed Cameras in NSW can either be equipped with a visible flash or an invisible infrared flash, depending on the specific camera model being used. Whether a mobile speed camera flashes during the day or night will depend on the type of flash it is using.
A Band A speeding fine would be appropriate if you were caught speeding between 31-40 mph in a 30-mph zone. Providing you accept responsibility for speeding, you will be required to pay a minimum £100 fine and receive three points on your licence.
You can't know instantly if a speed camera caught you, but you'll get a notice in the mail, or you can check online via your state's government or transport authority website using your vehicle details. A flash doesn't guarantee a ticket, as cameras can test or catch other cars, but official portals allow viewing photos if you are fined, so check them for updates.
Speed cameras trigger based on a set limit plus a tolerance, often around 10% + 2 mph (or ~3 km/h) over the posted limit, though this varies by region and camera type (fixed vs. average). While you can be caught at 1 mph over, authorities typically enforce at higher thresholds, like 4-10 mph over in a 30-40 mph zone, with some systems subtracting minor equipment error, effectively giving you a buffer.
Speed and red-light camera penalties typically arrive within two weeks, although NSW can take up to 28 days. In Tasmania, fines may appear electronically in as little as four days.
Most police forces have a tolerance of 10% plus 2mph above the limit before a speed camera 'flashes'.
The "best" excuse for a speeding ticket appeal is usually a legally recognized defense, like a medical emergency, an unavoidable situation (e.g., vehicle breakdown), or proving the speed detection equipment was faulty, as these address the circumstances of the offense, not just an excuse. Common, though less reliable, excuses involve "I didn't see the sign" or "keeping up with traffic," but these often fail in court; being respectful and challenging the evidence (like radar calibration) offers a better chance.
The minimum speeding fine varies significantly by location (state/territory in Australia, for example) and how much you exceed the limit, but generally starts around $100 AUD for exceeding the limit by the smallest margin (e.g., less than 10 km/h), with some areas like Western Australia having no demerit points for this smallest infraction, while NSW might have a $93 fine for similar minor speeding, and South Australia starts at $187 with points.
Flash but no ticket? It's possible (though not common) that you might see a flash and never receive a ticket. Older cameras using film can run out, and some flashes are test flashes. That said, most modern cameras are digital and always ready.
No, you cannot legally go 5 km/h over the speed limit; any amount over is technically speeding and can result in fines, demerit points, or other penalties, though some sources suggest a slight "tolerance" for minor infringements with speed cameras, and police might give warnings for small excesses like 5-10 km/h, but it's never guaranteed.
The mobile speed cameras using radar can detect your speed from several hundred metres away. However, for an accurate, prosecutable reading, the operator typically needs to be within a few hundred metres. The key point is they will have your speed locked in well before you get close enough to spot them.
You can get a speeding ticket for going any amount over the limit, but most places have a small tolerance (like 10% + 2 mph or a few km/h) before enforcement cameras consistently catch you; however, a police officer can ticket you for even 1 km/h over, especially in school zones or for higher speeds, leading to fines, demerit points, or license suspension.
Exceeding the speed limit by more than 15 mph (24 km/h) with a speed of greater than 55 mph (89 km/h) or travelling faster than 80 mph (129 km/h) results in a minimum 30-day license suspension.
Yes, it is illegal to block someone overtaking you by speeding up under Road Rule 145 – driver being overtaken not to increase speed.
The best defense for a speeding ticket often involves challenging the accuracy of the speed measurement, questioning the clarity and visibility of speed limit signs, disputing the officer's observations, or proving a necessity or mistake of fact.
The most believable excuses are short, specific, and tied to legitimate responsibilities or unavoidable situations. Examples include sudden illness, a medical appointment that couldn't be scheduled outside work hours, urgent family needs, or car/transportation issues.
You can:
Speeding between 31 and 40 mph in a 30 mph zone constitutes three penalty points on your driving license. In addition to penalty points, a fine amounting to a proportion of your weekly income will also be imposed. More severe speeding offences can attract larger fines.
Speed camera tolerance refers to the margin of error or buffer added to a vehicle's detected speed before a fine is issued, typically around 10% plus a small fixed number (e.g., 2-3 mph/km/h) for guidance, though this varies by region and police force, with some locations having specific rules (like 2 km/h for fixed cameras in Victoria) or no official tolerance at all (like WA). This buffer accounts for speed camera inaccuracies and vehicle speedometer variations, but it's only guidance, and police can choose stricter enforcement.
They don't capture your speed in a single flash. Instead, they'll monitor your speed over a length of road. This is so people don't slow down just before they see a camera and then speed up again afterwards.
The minimum speeding fine varies significantly by location (state/territory in Australia, for example) and how much you exceed the limit, but generally starts around $100 AUD for exceeding the limit by the smallest margin (e.g., less than 10 km/h), with some areas like Western Australia having no demerit points for this smallest infraction, while NSW might have a $93 fine for similar minor speeding, and South Australia starts at $187 with points.
This means that the minimum reading on a speed camera which can result in a fine is 3 km over the limit. But yes, you could be fined for doing 3km over the limit.
Traffic Fine Discounts
While these fines must be paid, the AARTO system offers an incentive for early settlement—allowing drivers to pay only 50% of the fine amount if they clear it within 32 days of receiving the infringement notice. This discount system is currently applicable in: Johannesburg.
