It is a checkpoint mission, but it has no time limit. It is essentially the reverse of Trial By Dirt, which is started by jumping on the Sanchez instead. To complete this mission, the player must clear each checkpoint without exiting or destroying the car. It is much easier than the previous Landstalker mission in Grand Theft Auto III, entitled A Ride in the Park.
The player can keep playing this mission once they've completed it. Each time the player beat their time record, they receive a higher prize (in money).
- Due to a bug in the game, the initial scores of both Trial By Dirt and Test Track will have the same time results once both scores are listed in the game's stats. Once both missions are played again and each time is beaten, the scores will be individual as they should be.
- If player completes Trial By Dirt before Test Track, the Test Track's time result will not show up in stats screen. So player should completes Test Track before Trial By Dirt for avoiding this bug but the same time results bug still can't fix.
