There are camels grazing on the roadsides all along the coastal road either side of Salalah. They have absolutely no fear of cars and will wander onto the road without any hesitation. It is cutomary when you see them to put on your hazard warning lights in order to warn oncoming vehicles as well as those behind you that there are camels on the road. So, if you see a car flashing its warning lights, slow right down, as you don't want to hit a camel.
The country is pretty safe. Remember they haven't been drive very long so be care while driving. Make sure that you take some kind of course before you drive on there driving habits. They like to speed and pass when it is not safe. Also they have cows/camels that will just walk right in the middle of the road.
