It depends on the land and how often they drive on it. If they are on it often the deer are a bit used to the vehicles being there and will be alert when the truck is there, but once it has gone will go right back to their business.
If the land has very little use they may shut down for the evening.
I think you did the right thing. You never know when/where a deer will come thru and prime time is not the time to move.
