On the afternoon of April 8, 2024, a total solar eclipse will sweep across parts of the United States, offering a stunning spectacle. For professional drivers, understanding the phenomenon of a total eclipse and knowing how to navigate the roads safely during this extraordinary occurrence are paramount.
A total solar eclipse occurs when the moon passes between the sun and Earth, completely obscuring the face of the sun. Weather permitting, some form of the eclipse will be visible throughout all 48 contiguous states, but to what extent and for how long depends upon the location. People within the less than 150-mile wide path of totality—where the moon’s shadow completely covers the sun—will experience a total eclipse. The sky will temporarily darken, as if it were dawn or dusk. According to The National Aeronautics and Space Administration (NASA), the path of totality will start in Texas at 1:27 PM CDT and slide northeast, ending in Maine at 3:35 PM EDT. Most places along the path’s centerline can expect a totality duration between 3.5 and 4 minutes. However, the entire event from first contact—the moment when the moon first "touches" the sun—to the end of the eclipse will last just under three hours. People outside the path of totality will witness a partial eclipse, where only a portion of the sun will be covered, giving it a crescent shape.
Amidst the celestial wonder, drivers must remain vigilant and be prepared to navigate unique challenges. Here are some indispensable tips to help ensure a safe journey during the total eclipse:
Plan ahead. Familiarize yourself with the timing and path of the eclipse to anticipate potential congestion. Cities within the path of totality are expected to attract hordes of sky gazers not only on April 8th, but also the weekend preceding the eclipse. Before heading out, check weather forecasts and traffic updates. Map out your destination, plan alternate routes and allow for extra travel time. If you use a GPS device, be sure it’s designed for commercial vehicles and has the latest maps and software. Also, avoid peak traffic periods, if possible. The worst traffic jams during the nation’s last total eclipse in 2017 were reported immediately after the eclipse ended, as large numbers of vehicles attempted to leave the viewing areas simultaneously.
Ensure your vehicle's readiness. Conduct a thorough pre-trip inspection to make sure your vehicle operates at its best. Amidst heavy traffic, any mechanical issues could exacerbate safety risks. Also, top off your fuel tank, and have some essentials, such as food and water, on hand in case of delays.
Expect rapid changes in lighting and visibility as the eclipse progresses. Lower your vehicle’s visor to shield yourself from directly viewing the eclipse and help protect your eyes from serious damage. As daylight diminishes, switch on your headlights for improved visibility. Exercise caution during the darkest phase of the eclipse, which will be like driving at night. Also, be aware that streetlights may not turn on immediately. Increase your following distance, and be prepared to react quickly to any potential hazards.
Stay alert and minimize distractions. Keep your focus on the task of driving by refraining from activities such as eating, changing radio stations or reaching for items in the vehicle. Watch for changes in traffic patterns ahead, and remain vigilant to potential hazards.
Be mindful of pedestrians. The eclipse will bring more people outdoors, especially in towns and cities along the path of totality. With their focus likely on the sky, pedestrians may not be fully attentive to traffic around them. Keep your eyes moving, and be prepared to stop.
Monitor fellow motorists. Watch for those drifting between lanes, rapidly accelerating or decelerating, braking abruptly, tailgating, or reacting slowly to traffic signals. These may be indicators that the driver's focus is elsewhere, such as observing the eclipse or snapping photos with their smartphone. Also, be cautious of motorists pulling over unexpectedly to view the eclipse, and maintain a safe distance from vehicles whose drivers may be wearing eclipse glasses, as these solar shades can greatly impair vision.
Beware of wildlife. Animals may behave unpredictably during the sudden darkness of the eclipse. Reduce your speed and remain alert, especially in rural areas where encounters are more likely.
Lastly, if you wish to observe the total eclipse on April 8th, plan ahead so you’re off the road and safely parked in a safe and legal location well before the eclipse begins, and remember to wear specialized eye protection for solar viewing to prevent the risk of serious eye damage.
While the total eclipse may be a captivating sight, it's essential to prioritize safety on the roads. By understanding the unique challenges presented by the eclipse and taking the appropriate precautionary measures, you can confidently navigate the roads amidst the awe-inspiring phenomenon unfolding in the sky above.
