What are Speed Camera missions?

These are optional side missions that you can do. Around the city, you will see yellow lines across the road. These missions can also be identified on the Mini-Map by looking for yellow car icons.

As you approach this mission, you will see a speedometer at the top of the screen along with some text below it. Whilst in a vehicle, you need to be going faster than the specified speed in the text.

If you achieve this, you will gain some Cash.
