Here's our walkthrough for Designated Driver, the second mission in "The First Dose" series from GTA Online's Los Santos Drug Wars update. This mission involves retrieving party supplies and then retaliating against the Lost MC. You can start this mission, and subsequent First Dose missions, from The Freakshop ('D' on the map).

In the second first dose mission, you must first make your way to the Jetsam Terminal and steal a truck cab. There are plenty of truck cabs around the terminal. Approach any one of them, and they will be highlighted on your mini-map.

Enter the truck cab and go to the front of the Jetsam Terminal to collect the party supplies. Reverse into the trailer and attach it to the cab.

Now deliver these supplies to The Freakshop. However, as you exit the Jetsam Terminal, you will be ambushed by a number of Lost MC biker gang members.

The supplies will catch on fire, and you must detach the truck cab from the trailer with the party supplies before it explodes. You can see how much health you have at the bottom-right corner of the screen. You must detach before the bar drops all the way down to zero.

You can detach the trailer by holding the 'H' key if you're on PC or the right d-pad on your controllers if you're on a console (PlayStation or Xbox).

Once detached, you'll be instructed to get revenge on the Lost MC members by infiltrating their clubhouse, which is surprisingly close to The Freakshop.

Make your way to the Lost MC clubhouse, and eliminate all the enemies before you can enter the house.

When you're inside, eliminate the remaining members, and look for their plans.

They are documents attached on a pinboard on one of the walls. We found ours inside one of the rooms by the bar.

After taking the picture, look for a duffle bag in the house. Ours was on the bar counter.

Pick it up and go to the drugs that are on the table inside the house. Pick them all up.

Leave the clubhouse and fight the incoming Lost MC members. Deliver the looted drugs to The Freakshop to complete the mission.

These missions do not have any timer, so you can stay in cover and take your time when eliminating these enemies.

With the Lost MC's plans in hand, you're ready to escalate things in the next mission: Fatal Incursion.
