When driving at highway speeds, how far ahead should a driver look?

Answer: A — Quarter of a mile

When driving at highway speeds, a driver should look at least a quarter of a mile ahead. This allows the driver enough time to react to potential hazards or changes in traffic flow. Looking too far ahead, such as two miles (choice D), can cause the driver to lose focus on the immediate surroundings. On the other hand, looking too short of a distance, such as just half a mile (choice B), can limit the driver's reaction time and lead to unexpected braking or swerving. Therefore, a quarter of a mile is a safe and effective distance to look ahead when driving at high speeds.
