A more thorough explanation:

Definition: Proper lookout is the responsibility of a driver to be careful and aware of their surroundings to prevent accidents with other vehicles or pedestrians.

Example 1: A driver is approaching an intersection with a stop sign. They must come to a complete stop and look both ways before proceeding to ensure there are no other vehicles or pedestrians in the way.

Example 2: A driver is driving on a busy highway. They must constantly scan the road ahead and check their mirrors to be aware of other vehicles and potential hazards.

These examples illustrate how a driver must be vigilant and aware of their surroundings to prevent accidents. By exercising proper lookout, drivers can avoid collisions and keep themselves and others safe on the road.
