Driver's observation.
As mentioned, you must be attentive to the different road signs. You must exhibit that you're able to focus on the road and know the different road signs. Aside from that, you should focus on your environment when driving.
For example, has it been constantly raining in your area? Then you must always look out for ‘slippery signs’ and reduce your speed. When weather conditions change, most of the time, road conditions are also affected. So make sure to be extra cautious and drive defensively. This way you'll be able to make the appropriate decisions when driving.
The practical driving test is designed to evaluate your general driving abilities. It will test your observation, attitude on the road, and your overall performance. Make sure you're well prepared by taking driving lessons and practice to pass your driving test.

In a nutshell, you need to make the driving examiner, sitting next to you, feel safe. When you demonstrate to the examiner that you are a safe and courteous driver on the road and you know about all the road rules, you will finish your driving test with flying colours.
