Final answer:
When scanning your driving environment, it is important to avoid fixating on one thing and scanning too quickly. However, constantly checking mirrors and adjusting speed while scanning are necessary.
Step-by-step explanation:
When scanning your driving environment, there are certain things that should be avoided. One of them is fixating for too long on one particular thing as you scan. It is important to continuously scan the environment to be aware of all potential hazards and changes in the road conditions.
Another thing to avoid is scanning too quickly and not thoroughly. This can cause you to miss important details and hazards on the road.
Adjusting your speed while scanning should not be avoided. It is important to adjust your speed as needed based on the conditions of the road and traffic.
Constantly checking your mirrors is also not something that should be avoided. Mirrors are important for monitoring the vehicles around you and staying aware of your surroundings.
