Summer might mean longer days and scenic drives, but for truck drivers, it also brings a unique set of challenges. From sweltering heat in the cab to unpredictable road conditions, staying safe and comfortable during the hottest months of the year takes planning and awareness.
Whether you’re hauling through the desert southwest or stuck in traffic on the I-95, here are some straightforward, driver-tested tips to help you stay cool and drive smart all summer long.
1. Beat the Heat in the Cab
Your truck is your office, and in the summer, it can feel more like a sauna. Here’s how to keep your cab cool and comfortable:
- Use Reflective Sunshades: A simple sunshade can drop your cab temperature by 10–15 degrees. Use them on your windshield and side windows when parked.
- Park Smart: Whenever possible, park in the shade. Even partial shade can make a big difference.
- Ventilate: Crack your windows or use vent visors to allow airflow without letting in rain or too much heat.
- Invest in a Fan or Portable AC: If your truck doesn’t have an APU or built-in climate control, a 12V fan or portable AC unit can be a game-changer.
- Dress for the Weather: Lightweight, moisture-wicking clothing helps regulate body temperature and keeps you dry.
2. Stay Hydrated
Dehydration can sneak up on you, especially in the cab with the AC blasting. You may not feel thirsty, but that doesn’t mean your body isn’t losing fluids through sweat and breathing. Dehydration can cause fatigue, headaches, and slower reaction times, so keep these tips in mind:
- Drink Water Regularly: Aim for at least 8 cups a day, more if you’re sweating a lot. Keep a refillable water bottle within reach.
- Avoid Sugary and Caffeinated Drinks: They might give you a quick boost, but they can also dehydrate you.
- Snack on Hydrating Foods: Fruits like watermelon, oranges, and cucumbers are great for hydration and energy.
3. Watch for Heat-Related Illness
Heat exhaustion and heat stroke are serious risks, especially if you’re loading, unloading, or doing inspections in direct sun. When you’re working outside or even sitting in a sunlit cab, your body can heat up faster than you think.
Know the signs of heat exhaustion:
- Heavy sweating
- Weakness or dizziness
- Nausea or headache
- Muscle cramps
- Pale or clammy skin
If you feel any of these symptoms, don’t try to power through. Get to a cool, shaded or air-conditioned area, hydrate with water or electrolyte drinks, and take time to rest. If symptoms worsen or don’t improve, seek medical help immediately.
4. Summer Road Hazards to Watch For
Safe summer driving isn’t just about staying cool; this season also brings unique road conditions that can catch even experienced drivers off guard.
- Tire Blowouts: Hot pavement increases tire pressure. Check your tires daily for wear and proper inflation.
- Construction Zones: Summer is peak season for road work. Slow down, stay alert, and follow posted signs carefully.
- Glare: Bright sun can reduce visibility. Keep sunglasses handy and clean your windshield regularly to reduce streaks and smudges.
- Sudden Storms: Summer thunderstorms can roll in fast. Reduce speed, increase following distance, and pull over if visibility drops too low.
5. Keep Your Truck in Top Shape
Your truck works hard in the summer, too. Prevent breakdowns and overheating with regular maintenance:
- Inspect coolant levels: Your engine will be working harder, and coolant helps prevent overheating.
- Test your AC: Don’t wait until you’re miles down the highway to realize it’s blowing hot air.
Look at belts and hoses: High temps can wear them down faster, so be sure to watch for cracks, leaks, or signs of aging.
- Clean your air filters: Dust and pollen levels rise in summer, so clogged filters can reduce airflow and performance.
6. Take Care of Yourself
Long hours in the heat can wear you down fast, both mentally and physically. Make time for rest, eat light meals, and listen to your body. A healthy driver is a safe driver.
And, as always, don’t forget sunscreen! Even through a windshield, UV rays can cause sunburn and long-term skin damage. Keep a bottle of SPF 30+ in the cab and reapply as needed. A sun sleeve or driving glove on your left arm can also help, as well as additional protection, such as SPF lip balm or a sun hat.
