Police use radar, laser and spotter planes to catch speeding cars and they can be located anywhere, and, the fines are very expensive. The extra speed is not worth it. More importantly wild animals and stock can wander over the roads during the night, jumping in front of your car, especially close to dusk and dawn and, if you are not careful, you will hit them and cause a bad accident possibly in a remote location which will mean that assistance can take a long time to come to the rescue. Drive more slowly at night as you will not be able to see wild animals or wandering stock until you are very close. When looking for animals, look for the reflection of the headlights on the eyes.
Animal eyes are very reflective and easy to spot at night.
Always have the front seat passenger stay awake with the driver to keep the driver awake and help spot animals. It is easy to get bored and fall asleep at the wheel, especially while driving at night. Expect more animals on the road the further north you travel , especially over the last 217kms after the Minilya turnoff from the main highway up the North West Cape into Exmouth. Kangaroos are the most unpredictable animals as they become blinded and panicked by car headlights and can jump in any direction, often straight into oncoming cars. You will also see foxes, emus, goats, rabbits, sheep and cattle.
