But did you know just how many different speed cameras there are operating on our roads? From average speed cameras to overhead cameras, mobile cameras, speedguns and night cameras, it's easy to get confused. Here's a guide to the most common camera types on our roads.

1. Motorway Average Speed Cameras
On motorways, these tend to be used during roadworks rather than all the time. They are different to normal motorway cameras. They record your speed between two points and calculate an AVERAGE of your speed overall.

2. Overhead Smart Motorway cameras
Can be overhead or on the floor. They ONLY trigger when you speed past them - different to average speed cameras. They used to only be switched on when the overhead signs are on, but the new Smart ones can catch anyone at any time

3. Handheld speedguns
These are used by police or volunteers at the side of the residential roads. The RADAR speed devices capture the speed of any passing car. They are highly visible patrols and anyone caught speeding can be issued a ticket.

4. Floor-based motorway speed cameras
These work in the same way as overhead cameras, but are positioned on the floor. They don't tend to be used these days but they trigger when driven past at speed.
