As the celestial stars align for a spectacular solar eclipse, scientists are issuing a different kind of starry-eyed warning: watch the road, not the sky! This grand astronomical event, where the moon photobombs the sun, is set to sweep across North America, turning day briefly into twilight and drawing thousands to its path of totality from Mazatlán to Indianapolis.

But before you pack your eclipse glasses and hit the road, there’s a cosmic caveat to consider. With the influx of eager sky gazers migrating towards the eclipse’s path, traffic jams are predicted to stretch longer than a Monday morning coffee line. Remember the 2017 eclipse? Some areas experienced a celestial-sized bottleneck, with congestion lasting up to 13 hours. It’s like Black Friday, but for solar enthusiasts.

Now, let’s talk science (and safety). A recent study has spotlighted a 31 percent spike in fatal car accidents during the 2017 total eclipse. It’s not the temporary darkness that’s the hazard—it’s the sheer volume of vehicles, the unfamiliar routes, the rush to reach the perfect viewing spot, and perhaps the odd distracted driver trying to catch a glimpse of the sun’s disappearing act.

Donald Redelmeier, the Sherlock Holmes of this traffic conundrum, points out that this isn’t just about cars and celestial bodies. It’s about the peculiar human behavior when faced with a rare skyward spectacle. From speeding to arrive on time to potentially unsafe roadside eclipse-watching, the excitement can lead to risky decisions behind the wheel.

So, as the eclipse casts its shadow, starting in Mexico at 9.51am MT and cruising into Texas by 12.10pm CT, let’s remember John Staples’ sage advice: respect speed limits, minimize distractions (yes, that includes your awe at the cosmic dance above), and keep a safe distance from the car ahead.

As we gear up for this stellar show, let’s not eclipse our common sense. Enjoy the celestial ballet, but ensure your eclipse experience is memorable for the right reasons. After all, the best way to appreciate a solar eclipse isn’t from the side of the road after a fender bender. Stay safe, stay savvy, and let the moon and sun have their moment while you keep your eyes on the road.
