Smart Summer Driving Tips to Beat the Heat & Stay Safe

While the longer days of summer certainly have their perks, extreme heat can take a real toll on drivers and fleets. Higher temperatures over an extended period can lead to a host of issues including dehydration and fatigue that make an already demanding job even tougher.

Staying cool isn’t just about comfortable. Heat-related discomfort can impact alertness and productivity, so it’s important to make a few small adjustments to ensure you’re prepared to handle the heat all summer long.

Stay ahead of dehydration

Staying hydrated is always a good idea but needs to be a top priority in hot weather. You lose fluids faster than you realize, particularly during long hauls or when working outside the cab.

Have plenty of water available and create a habit for yourself of refilling whenever you stop. Sports drinks or juice can help replenish electrolytes but avoid caffeine when possible. Although tempting on long hauls, it acts as a diuretic and can worsen dehydration.

Remember, if you wait to drink until you feel thirsty, you’ve already waited too long. Drink consistently throughout the day instead.

Adjust your routine when you can

Just like you’d adapt how you drive for rain, snow, or fog, extreme heat calls for its own adjustments. While you can’t adjust your route, sometimes you can make small changes in your day. When possible, avoid strenuous activity during the hottest parts of the day. Take regular breaks to cool down and step out of direct sunlight.

FoodPRO, a wholesale restaurant supplier and food-service distributor of fresh cut steaks, fish, and produce, as well as non-perishable groceries and food service supplies for over 80 years throughout Maryland, Northern Virginia, West Virginia, D.C., and Pennsylvania, knows something about managing comfort with routine. Their newest unit, a Mack Pioneer sleeper, features an APU that the driver loves, according to Director of Transportation Christopher Ziegler. Most of their 31 units, however, are day cabs.

Ziegler says the drivers’ behavior is the key to running safely and efficiently in all types of weather. “Being in food distribution, the routes must make logistical sense,” Ziegler says. “We do our best to spread out the workload as much as possible.”

Make the cab work for you

Your cab environment plays a big role in how well you handle summer conditions. Adhering to simple habits like choosing shaded parking spots can make a noticeable difference when you climb back in.

Make sure vents are clear and cabin air filters are clean so your A/C can do its job efficiently. Breathable seat covers can also help reduce heat buildup on long stretches behind the wheel.

Keep an eye on your equipment

Extreme heat can also impact your trucks. High temperatures increase the risk of engine overheating, tire blowouts, and brake fade. Regular inspections are especially important in summer.

Check tire pressure frequently, monitor coolant and antifreeze levels, and pay attention to any warning signs before small issues become big problems. A few minutes of PM can save hours of downtime later.

Plan and stay prepared

Checking the forecast before each run helps you anticipate extreme conditions instead of reacting to them. Keep summer‑specific gear on hand, like cooling towels, extra water, sunscreen, and electrolyte drinks.

What you wear can be a big help. Lightweight, loose‑fitting, or moisture‑wicking clothing helps regulate body temperature, while hats and sunglasses provide extra protection when you’re outside the cab.

Summer heat is predictable, so use that knowledge to stay comfortable and safe no matter the number on the thermometer.
