How to Prepare Fleet Vehicles for Seasonal Changes (Spring, Summer, and Fall)

Managing a fleet of vehicles is more than keeping them fueled and on the road—it’s about planning ahead. Seasonal changes can quietly wear down fleet vehicles, leading to unexpected breakdowns, downtime, and costly repairs. For commercial customers and local businesses, even one disabled vehicle can disrupt operations, delay deliveries, and impact customer trust.

At Darrah’s Towing, we’ve spent years working alongside businesses that rely on dependable fleets every single day. From service vans and delivery trucks to construction vehicles and commercial fleets, we’ve seen firsthand how proactive seasonal preparation keeps businesses moving—and how skipping it can bring operations to a halt.

This guide is designed to help business owners and fleet managers prepare their vehicles for spring, summer, and fall, reducing risk, improving safety, and protecting long-term investments.

Why Seasonal Fleet Preparation Matters

Fleet vehicles operate under far more stress than personal vehicles. They rack up miles faster, carry heavier loads, and operate on strict schedules. Seasonal shifts—temperature swings, road conditions, humidity, and weather patterns—can accelerate wear and tear if fleets aren’t properly maintained.

According to industry data, preventive maintenance can reduce vehicle breakdowns by up to 30%, saving businesses thousands annually in repair costs and lost productivity. Seasonal preparation is a major part of that preventive strategy.

Darrah’s Towing has supported commercial fleets through every type of roadside emergency imaginable. The businesses that experience fewer disruptions are almost always the ones that plan ahead.

Spring Fleet Preparation: Recovering from Winter Wear

Spring is a transition season—and one of the most critical times to inspect fleet vehicles. Winter conditions can leave hidden damage that doesn’t always show immediate symptoms.

1. Inspect Tires Thoroughly

Winter cold causes tire pressure fluctuations, uneven wear, and sidewall stress.

Spring tire checklist:

• Check tread depth and look for uneven wear

• Inspect for cracks, bulges, or punctures

• Adjust tire pressure to manufacturer recommendations

• Rotate tires to extend lifespan

Fleet vehicles with neglected tires are far more likely to suffer blowouts once spring driving increases.

2. Check Suspension and Alignment

Potholes and rough winter roads can knock vehicles out of alignment and damage suspension components.

Signs to watch for:

• Pulling to one side

• Uneven tire wear

• Vibrations at highway speeds

Addressing alignment issues early prevents costly tire replacement later.

3. Replace Worn Wiper Blades and Check Fluids

Spring rain demands clear visibility.

Key checks include:

• Windshield wiper blades

• Washer fluid levels

• Brake fluid, transmission fluid, and coolant

Small items like wipers are often overlooked—but visibility issues can quickly turn into accidents or roadside calls.

Summer Fleet Preparation: Preventing Heat-Related Breakdowns

Summer heat is one of the leading causes of roadside failures for commercial vehicles. Engines, batteries, and cooling systems are under constant pressure in high temperatures.

1. Cooling System Inspection

Overheating is one of the most common summer breakdown causes we see at Darrah’s Towing.

Inspect:

• Radiator and hoses for leaks or cracks

• Coolant levels and condition

• Fans and belts for wear

A failing cooling system doesn’t just cause delays—it can destroy an engine.

2. Battery Testing

Heat shortens battery life more than cold. Many batteries that survived winter will fail in summer.

Fleet managers should:

• Test battery charge and output

• Clean corrosion from terminals

• Replace batteries nearing end of service life

Proactive battery replacement costs far less than emergency towing during peak business hours.

3. Air Conditioning System Maintenance

For fleet drivers, AC isn’t a luxury—it’s a safety and productivity tool.

Ensure:

• Refrigerant levels are correct

• Cabin filters are clean

• Compressors are functioning properly

Uncomfortable drivers fatigue faster, increasing the risk of accidents.

Fall Fleet Preparation: Getting Ahead of Winter

Fall is about preparation. Waiting until winter arrives is often too late.

1. Brake System Inspection

Increased moisture and falling leaves reduce traction, placing more demand on braking systems.

Check:

• Brake pads and rotors

• Brake fluid condition

• ABS warning indicators

Early brake service prevents emergency failures during winter conditions.

2. Tire Readiness for Cooler Temperatures

As temperatures drop, tire pressure decreases.

Fall tire prep includes:

• Adjusting pressure

• Checking tread depth for wet and slippery roads

• Planning winter tire installation if required

Proper traction is one of the most effective ways to prevent seasonal accidents.

3. Electrical and Lighting Systems

Shorter days mean more driving in low-light conditions.

Inspect:

• Headlights, brake lights, and turn signals

• Dashboard warning systems

• Backup and work lights for commercial vehicles

Visibility protects both drivers and other road users.

Building a Seasonal Fleet Maintenance Schedule

One of the most effective strategies we recommend to commercial clients is creating a seasonal fleet checklist.

A strong plan includes:

• Scheduled inspections at each seasonal change

• Driver reporting procedures for early warning signs

• Maintenance logs for every vehicle

• Emergency roadside response planning

At Darrah’s Towing, we often work with fleet managers after a breakdown occurs—but the most successful businesses are the ones that involve us as part of their preparedness strategy, not just their emergency response.

Real-World Experience from the Road

A local commercial client recently shared their experience after implementing seasonal fleet preparation:

“Before working closely with Darrah’s Towing, we dealt with constant breakdowns—especially during summer. Since putting seasonal maintenance checks in place, our roadside calls have dropped significantly, and when we do need help, Darrah’s Towing is fast, professional, and understands commercial fleets. They’ve become a partner we trust, not just a towing company.”

This kind of long-term relationship is what Darrah’s Towing has built over years of service—supporting businesses when they need it most.
