Saskatchewan Driver Education GDL Class 7 Learner Practice Test

How far ahead should drivers scan the road when on a highway?

1. At least 12-15 seconds ahead

2. At least 5-10 seconds ahead

3. Only as far as they can see

4. About 30 seconds ahead

The correct answer is: At least 12-15 seconds ahead

Scanning the road ahead on a highway is crucial for safe driving, as it allows you to anticipate potential hazards, changes in traffic flow, and other important events that may require your attention. The recommended scanning distance of at least 12-15 seconds ahead is based on the speed at which vehicles typically travel on highways. This distance gives you enough time to react appropriately to any situations that may arise, such as vehicles slowing down, merging traffic, or obstacles in the road. By scanning this far ahead, you can maintain a safe following distance, better assess the conditions of the road, and plan your maneuvers—whether that's changing lanes, merging, or slowing down. This proactive approach significantly enhances your ability to make informed decisions while driving, thereby increasing your safety and the safety of others on the road. While scanning closer—such as 5-10 seconds ahead—can be useful in certain situations, it may not provide sufficient time to react to more distant hazards typical on highways. Scanning only as far as one can see may limit the driver's awareness and ability to respond to potential dangers in a timely manner. Similarly, while scanning about 30 seconds ahead might seem beneficial, it can lead to information overload and distract from immediate concerns closer to
