When driving on a highway where the two directions have land in between them and often there are many trees in that area, it would be good Sea on the map where the entrances are for authorized Vehicles only that go from one side of the highway to the other side of the highway. This is often where maintenance Vehicles Park and also law enforcement vehicles. It is often hard to see if there are any vehicles parked there until you actually pass the area especially if there are a lot of trees there.
