Driving near big game
The only animals which are likely to pose a threat to vehicles are elephants – and generally only elephants which are familiar with vehicles. So, treat them with the greatest respect and don't 'push' them by trying to move ever closer. Letting them approach you is much safer, and they will feel far less threatened and more relaxed. Then, if the animals are calm, you can safely turn the engine off, sit quietly, and watch as they pass you by.
If you are unlucky, or foolish, enough to unexpectedly drive into the middle of a herd, then don't panic. Keep your movements, and those of the vehicle, slow and measured. Back off steadily. Don't be panicked, or overly intimidated, by a mock charge – this is just their way of frightening you away. Professionals will sometimes switch their engines off, but this is not for the faint-hearted.
