Always Pull Over for Police
If one member is pulled over by the cops, it is customary for the rest of the gang to pull over in solidarity. This shows that the club acts as a unit, in addition to being an intimidation tactic if the police start to get a little handsy.
Newbies Do the Dirty Work
In order to get noticed by the gang, you need to stick your neck out a little bit. They call these individuals "prospects." These are people who are not affiliated with the gang but decided that they wanted to be part of it somehow, so they help commit crimes.
