The radar might pick you up from further away but the camera part wouldn't be effective over any more than about 200m. Vehicle mounted radars, on the other hand, are effective for as far as you can see.
The camera will photograph a speeding vehicle at an average distance of 12 metres.
We don't know what speed threshold will be set for prosecution. The cameras are accurate to +/- 2%, which means that you could receive a ticket in the mail for a speed infraction at little over the speed limit – so be warned.
Speed and red light cameras
Mobile cameras use radar to detect each vehicle's travel speed. If a vehicle is detected exceeding the speed limit or running a red light, the camera and flash are activated to take a photo and a fine is issued.
This tolerance deducts two km/hr from a vehicle's detected speed for fixed digital safety cameras. For mobile cameras, a tolerance of three km/hr or three per cent for speeds over 100km/hr is deducted. Police can also apply an additional tolerance at their discretion.
The maximum fine depends on how much faster than the speed limit you were driving. You can be fined: 10 penalty units for driving less than 35 km/hour over the speed limit. 15 penalty units for driving at 35 km/hour or more but less than 45 km/hour over the speed limit.
A driver will be charged with the offence of excessive speeding if they exceed the speed limit by more than 25km/h or drive faster than 130km/h. Guilt will depend on the facts and circumstances, with the prosecution having to prove that the person charged was driving the car and doing so over the speed limit.
Speed cameras will typically only flash when you've been caught speeding. However, there are multiple comments in online forums about speed cameras flashing when the motorist is adamant they were below the speed limit. As mentioned, some types of speed cameras don't flash at all.
You'll either be offered a speed awareness course, be issued a speeding ticket, or – in the most dangerous circumstances – you'll be sent to court, where you'll receive a fine, points on your licence or a driving ban.
Driving slowly
According to the NSW Road Rules you cannot drive so abnormally slowly that you cause an obstruction. An example of driving 'abnormally slowly' would be if you were travelling at a speed of 20 kilometres per hour on a road with a speed limit of 80 kilometres per hour.
If you're still concerned that you may have been caught, you might be able to check for any outstanding issued fines in some states. In NSW, you can use the Service NSW app, but most other states require a phone call to the relevant department if you don't have an infringement reference number.
Average speed enforcement works by measuring the amount of time it takes a heavy vehicle to drive between two points and then calculates the average speed of the vehicle. If the vehicle's average speed exceeds the speed limit for the length of road, the driver will receive a penalty for speeding.
If a vehicle is detected speeding, a digital image of the vehicle is recorded including the type and the number plate of the vehicle. Fixed digital speed cameras have the capacity to measure speed in both directions.
NSW Police can issue a licence suspension at the roadside if you are caught speeding by more than 45km/h over the speed limit. Police also have the right to impound your vehicle or confiscate your vehicle's number plates. These offences carry demerit points that will be added to your record.
? In NSW there is a 10% speed tolerance before the camera will snap a offending driver going over. Note: there is no leniency throughout school zone hours.
Contrary to popular belief, it's illegal to start accelerating when a speed sign becomes visible. It's also illegal to start accelerating when the numbers are readable. In short, you're supposed to wait until after you pass the sign; never before.
Unless you are pulled over by the police while driving, you will typically receive a penalty notice in the mail. The penalty notice will set out the fine owed and the demerit points incurred.
Immediate licence suspension will apply to: a person caught driving 45 km/h or more over the speed limit or 145 km/h or more in a 110 km/h zone (these motorists are also subject to vehicle impoundment)
Demerit points remain active for 3 years from the date that an offence occurred. If demerit points are accrued across multiple offences/dates, the demerit points will expire according to each offence date.
Police and other authorised people can give you a fine if they think you have broken the law. A fine means you must pay money as a penalty. You may not know you have a fine until you get an infringement notice in the mail.
Yes and no - it's not illegal to drive a bit under the speed limit, but if you drive abnormally slowly then you could be committing an offence.
