What is an essential practice when you are behind the wheel at night?

Using high beam headlights when legal is an essential practice for nighttime driving because high beams illuminate a larger area and provide better visibility in dark conditions, allowing drivers to spot potential hazards more easily. High beams effectively enhance nighttime driving by improving the driver's ability to see further down the road, making it easier to identify obstacles, pedestrians, or other vehicles that might be obscured in low light.

However, it is vital to switch back to low beam headlights when other vehicles approach or when driving in well-lit areas to avoid blinding other drivers. This thoughtful use of headlights increases overall safety for everyone on the road. By using high beams when appropriate and legal, drivers can significantly enhance their visibility and reaction time, which is crucial for safe nighttime driving.
