As the solar eclipse approaches, the RAC has issued a safety advisory for motorists, specifically targeting those whose vehicles lack automatic headlight systems. The organization warns that the sudden reduction in natural light could create hazardous driving conditions, making it difficult for other road users to see vehicles that are not illuminated.

While modern vehicles equipped with automatic sensors may detect the change in ambient light and engage their lights independently, the RAC emphasizes that drivers of older models or those with manual systems should be prepared to turn their headlights on manually. The goal of this guidance is to ensure vehicle visibility throughout the duration of the eclipse, reducing the risk of accidents caused by the temporary dimming of the sun. There is no disagreement regarding the safety recommendation, though the extent of the visibility drop may vary depending on the specific geographic location and the percentage of totality experienced by the driver.
