Georgia Commercial Driver License Practice Test

When is it safe to use high beams while driving?

1. When there are no oncoming vehicles within 500 feet

2. Only at night

3. When it's foggy

4. During rainstorms

The correct answer is: When there are no oncoming vehicles within 500 feet

Using high beams while driving is safest when there are no oncoming vehicles within a certain distance, typically 500 feet. This is because high beams provide a greater range of visibility but can blinding to other drivers. Keeping high beams off when facing oncoming traffic helps to ensure the safety of everyone on the road, as it allows for better visibility and reduces the risk of accidents. While it might seem practical to use high beams only at night, the primary consideration is more about the presence of oncoming vehicles rather than the time of day. Using high beams in foggy conditions can be hazardous, as the light reflects off the fog, reducing visibility. Similarly, during rainstorms, high beams can cause glare and impair visibility for both the driver and other road users, making it unsafe to use them in these situations. Hence, the use of high beams should be carefully considered based on surrounding traffic conditions rather than just the time of day or weather alone.
