Part of learning to drive involves different types of road conditions. Different from driving around suburban streets, the country throws up a variety of challenges.
Country driving is often on winding roads with rough edges. Sharp corners, crests, hill climbs and steep descents. Rural areas can often mean slippery roads due to mud being brought on to the roads by farm vehicles. Also, when away from built up areas the chance of meeting wild animals increases, especially at dusk: kangaroos and wombat if hit, can cause extensive damage to vehicles.
In the country you might come across many unmade roads, which are very different to drive on than sealed roads, and they need to be treated as such. On unmade roads the surface is often loose and slippery, with ruts and potholes made by rain and lack of upkeep.
Weather conditions can cause fog in the winter to be more prevalent than in built up areas, and haze in the height of summer.
So, as you can see the more practice you get with a supervisor as a learner, the better you will be prepared, when you get your provisional licence.
