Summer is officially in full swing, and with it comes rising temperatures, hotter pavement, and longer daylight hours on the road. While it might not be the first thing on your mind during a hot shift, idle time is one of the most important things to monitor this time of year.

At Carter Express, we know how hard you work—and how much the summer heat can take a toll. That’s why we want to talk about why limiting idle time matters more than ever, and how you can help protect your equipment, improve fuel efficiency, and keep your cab comfortable without unnecessary engine strain.

The Real Cost of Summer Idling

Let’s break down what extended idling in the summer really means for your truck and for Carter Express as a whole:

1. Fuel Use Adds Up Fast

An idling engine burns about half a gallon to a gallon of diesel per hour. That may not sound like much, but over the course of a week or a month, especially in hot weather when the A/C is running, it adds up quickly. Multiply that across our entire fleet, and we’re talking tens of thousands of dollars in lost fuel—fuel that could be used more effectively keeping freight moving.

2. Heat Accelerates Wear and Tear

Engines are made to run, but they’re also made to move. Sitting idle for long periods—especially in 90+ degree heat—puts stress on cooling systems, turbochargers, batteries, and other components. Idling also leads to more carbon buildup, which affects performance and can lead to more frequent maintenance needs and unexpected downtime.

3. Reduced Lifespan of Key Equipment

A truck that idles several hours a day will hit maintenance milestones faster and require earlier repairs. That includes everything from oil change sand filter replacements to exhaust system maintenance. The more efficiently we run, the longer your equipment stays in top shape—which means fewer shop visits and more time on the road.

4. Environmental Impact Matters

Excessive idling creates unnecessary emissions—plain and simple. As a responsible carrier, Carter Express is committed to reducing our environmental footprint. Every minute you cut back on idle time helps us meet sustainability goals and remain a forward-thinking, environmentally conscious fleet.

But What About Staying Comfortable?

We get it—summer can be brutal, and your comfort is a priority. You’re working hard to deliver freight safely and on time, and it’s important to rest and recharge during downtime. Here’s how you can stay cool and minimize idle time:

Carter Tips for Smarter Idling:

• Use APUs: If your truck is equipped with an Auxiliary Power Unit (APU), take advantage of it. APUs are designed to provide climate control without burning as much fuel.
• Plan Smart Breaks: Look for shaded parking when possible or take breaks during cooler parts of the day. Even a little shade can go a long way.
• Watch the Shutdown Settings: Be mindful of automatic idle shutdown features—don’t override them unless necessary.
• Perform Pre-Trip Checks: A properly functioning A/C system and cooling system are key. Report any issues ASAP so we can keep your truck comfortable without over-relying on idle time.
• Keep Windows Covered: Use sunshades or thermal curtains to block heat buildup in the cab during breaks.

Our Commitment to You

At Carter Express, we’re always looking for ways to support you better—and that includes keeping our fleet running efficiently and comfortably through the summer months. Reducing idle time helps all of us by:

• Saving fuel
• Reducing maintenance downtime
• Supporting a cleaner environment
• Extending the life of our fleet

It’s a team effort, and your awareness and attention to idle habits make a real difference.
