Okay, so everyone hates getting caught on camera. However, safety cameras are good at reducing vehicle speeds and cutting down the number of crashes.

Only drivers breaking the speed limit, and therefore breaking the law, get caught.

Fixed safety cameras
All fixed site safety cameras are easy to see and are placed at locations where there's likely to be a safety benefit. Their main purpose is to slow the traffic down in areas where there have been a lot of road accidents.

Mobile safety cameras
As well as fixed sites there are mobile safety camera units. These are used to enforce speed limits in-between the fixed sites. They're particularly useful in reducing the 'halo effect' around the fixed site, where drivers slow down for the camera and speed up after it.
