How to Beat the Heat and Safeguard Your Summer Road Trip

Climate Change Extreme Heat Can Ruin Your Road Trip. Here’s How to Prepare

Introduction

As the hottest summer of what is expected to be the hottest year on record winds down, millions of American families are preparing to hit the road for a brief respite. However, extreme heat fueled by climate change poses challenges for road travelers. From buckling highways to roadside fires, tire failures, and soaring gas prices, the impact of heat on road trips cannot be ignored. In this report, we will discuss the effects of extreme heat on road travel and provide advice on how to prepare for a safe and enjoyable journey.

Buckled Roads: A Hazard on Highways

Highway engineers refer to the phenomenon of overheated segments of concrete expanding and colliding as “buckling.” Buckling can create a bulge on the road surface or even lead to a road rupture that can damage a vehicle’s axle. Asphalt, on the other hand, can become soft in triple-digit temperatures, and continuous traffic can cause tire-track depressions and lead to cracking, potholes, and erosion.

While statistics on buckling and potholes are not readily available, experts suggest that regions experiencing dramatic swings between winter and summer temperatures, known as a freeze-thaw cycle, are more prone to such issues. However, extreme heat alone can cause roads to buckle by expanding concrete beyond its pressure tolerance. Without measures to address climate warming, the cost of road surface repairs is expected to increase significantly by 2050. Therefore, it is crucial to consider the effects of extreme heat on roads when planning a road trip.

Smoke and Fire: Hazards Along the Way

Roadside fires caused by extreme heat and dry conditions are becoming larger, denser, and more challenging to manage. Smoke plumes from these fires can impair visibility and pose risks to drivers. The American Association of State Highway and Transportation Officials states that roadside fires are increasing across the United States, partially due to climate change and increased traffic volumes.

Simple measures can help prevent roadside fires, such as avoiding parking vehicles on dry vegetation and securing tow chains to prevent sparks. Being aware of the risks of roadside fires and taking necessary precautions can ensure a safer road trip.

Tire Failures: A Hot Road Hazard

Extreme heat can have a detrimental impact on tires, making them more susceptible to failures. Hot air expands, and when combined with friction against the road surface, tire failures can occur. Underinflated tires are particularly dangerous in extreme heat because softer tires make more contact with hot pavement, increasing the risk of blowouts. It is also important to avoid using winter tires on hot roads, as their rubber compounds are softer and more prone to heat-induced blowouts.

Regularly checking tire pressure, especially before embarking on long trips, and ensuring tires are properly inflated can help prevent tire failures in extreme heat. By adhering to these measures, road travelers can reduce the risk of accidents and ensure a smoother journey.

Rising Gas Prices: The Impact of Climate Disasters

Extreme heat, hurricanes, and storms can disrupt fuel infrastructure, leading to higher gas prices. Power outages and damage to terminals, refineries, and pipelines can limit the supply of fuel, while reduced refinery capacity for safety reasons can further exacerbate the situation. Additionally, extreme heat can reduce fuel efficiency, resulting in increased fuel consumption and expenses.

Climate policy decisions can also influence fuel prices, as seen in Washington state, where a new carbon “cap-and-invest” program raised gas prices. Managing existing resources and prioritizing supply can be challenging, especially during climate disasters. Being mindful of rising gas prices and considering fuel costs when planning a road trip can help avoid budgetary strain.

Conclusion

Extreme heat poses significant challenges for road travelers by affecting road conditions, increasing the risk of tire failures, and impacting gas prices. However, by being aware of these challenges and taking appropriate measures, road trips can still be enjoyable and safe. Checking road conditions, planning breaks in shaded areas, ensuring proper tire inflation, and budgeting for potential gas price fluctuations are key considerations. Ultimately, adapting to the effects of climate change is essential for road travelers to make the most of their summer adventures while prioritizing safety and sustainability.
