What are Time Trial missions?

These are optional side missions that you can do. Around the city, you will see start banners. These can also be identified on the Mini-Map by looking for checkered flag icons.

To start these missions, you first need to drive through the starting line from the correct side.

At this point, a timer will start, and new markers will appear. You will need to drive through all the markers that appear within the time limit.

 If you achieve this, you will gain some Cash.
