Final answer:
When driving on open highways, drivers should look ahead for changes in traffic flow, road conditions, and environmental factors to ensure safety and prevent accidents.
Step-by-step explanation:
On open highways, it's essential for drivers to be aware of their surroundings and search ahead for potential hazards. Three important things you should look for include:
- Changes in Traffic Flow: Look for brake lights, merging vehicles and changes in traffic patterns.
- Road Conditions: Be alert for any roadwork, obstacles in the road, or changes in road quality, which may affect your vehicle's handling.
- Environmental Factors: Watch for animals crossing, weather conditions, and poor visibility which could require additional braking time or alternate routes.
Being vigilant and proactive in identifying these factors early can prevent accidents and ensure a safe journey.
