Night Ops

I was looking on google maps of some nearby places I wanted to visit, and I found what looks like some construction site/quarry. I was going to go check it out, but I remembered that one of the challenges was to take a picture from inside a construction vehicle (I think). What sort of security measures are on construction vehicles; locks, alarms, etc?

In my area at least there's no sort of alarm system on them. Heck, sometimes they leave them unlocked with the keys in the ignition.
