When is it acceptable to drive with your lights on high-beam?

Answer: D — When driving open country without other cars near

High-beam lights are used for visibility in dark and poorly lit areas, particularly on open highways or roads. In heavy traffic, it is not acceptable to use high-beam lights as it can blind other drivers and increase the risk of accidents. Similarly, when approaching an intersection, it is important to switch to low-beam lights to avoid distracting or blinding other drivers. Driving behind another vehicle also requires the use of low-beam lights in order to prevent blinding the driver in front. Therefore, the only acceptable scenario to drive with high-beam lights is when driving in open country without other nearby cars.
