Animals. When passing animals, drive slowly. Give them plenty of room and be ready to stop. Do not scare animals by sounding your horn, revving your engine or accelerating rapidly once you have passed them. Look out for animals being led, driven or ridden on the road and take extra care. Keep your speed down at bends and on narrow country roads. If a road is blocked by a herd of animals, stop and switch off your engine until they have left the road. Watch out for animals on unfenced roads.
