This achievement is worth 20G and can be achieved on mission 10, Violence and Timing.
There are six different types of vehicles. Only five are required to attain the achievement.
This will be easiest to achieve on regular or recruit difficulty.

1) Once you load this mission, you will belay from a moving helicopter onto a moving truck. Shoot the enemies riding in the truck and jump into it. This is the first vehicle you will hijack.

2) As you are driving this vehicle, lean out of the vehicle and hijack a moving cargo truck with a tarp on the back.

3) Once again do the same trick, but this time commandeer a moving cargo truck with open supplies in the back.

4) And again... but this time you want to repossess an armoured truck.

5) Finally, drive along the road until you pass a civilian car or van on the side of the road. Pull up and steal one of these vehicles. Either will do.



Tip: If you want to acquire the 'Keeping This One' achievement that is also available on this map, restart the mission once you have the 'Test Drive' achievement. It should only take 2-3 minutes from spawning to acquire.
