You’ve seen it before—a car cutting off a semi-truck, slamming the brakes, or hanging out in a truck’s blind spot. Maybe you’ve even done it yourself without realizing the danger. But here’s the reality: sharing the road with an 80,000-pound truck isn’t the same as driving next to another car, and small mistakes can have life-altering consequences.
Every year, thousands of accidents occur because passenger vehicle drivers don’t fully understand how trucks move, brake, and react. According to the Federal Motor Carrier Safety Administration (FMCSA) from 2010 to 2020, the number of large trucks involved in fatal crashes jumped by nearly 39%, reaching an astonishing 4,842 incidents.
Most drivers assume truckers are the ones causing accidents. But here’s the shocking truth: in fatal crashes between a passenger vehicle and a semi-truck, the car’s driver was at fault 72.7% of the time. That means most of these deadly collisions could have been avoided if passenger vehicle drivers understood the basic rules of driving near trucks.
So, how do you stay safe? You’ve probably heard the usual advice—avoid blind spots, give trucks space, don’t cut them off. But truckers, who spend thousands of hours on the road, have insights most drivers never think about—simple, game-changing habits that could prevent accidents and save lives.
At Alcoa® Wheels, we know that safer trucks mean safer roads for everyone. That’s why we engineer high-performance aluminum wheels designed to improve truck handling, reduce heat buildup, and enhance braking performance. However, even with the best equipment, safety ultimately comes down to the driver. That’s where defensive driving makes all the difference.
Truckers vs. Everyday Drivers: The Defensive Driving Training Gap
Defensive driving is more than just a concept—it’s the foundation of safe driving, especially when sharing the road with massive semi-trucks. It means staying alert, anticipating potential hazards, and making proactive choices that keep you and others on the road safe. While all drivers are encouraged to use defensive driving techniques, semi-truck drivers receive extensive training that goes far beyond what’s required for everyday motorists.
Truckers don’t just hop in and start driving—before they ever hit the road, they complete intensive Commercial Driver’s License (CDL) training, which far exceeds what’s required for everyday drivers. This includes defensive driving courses that go far beyond what the average driver learns in driver’s ed.
In states like Ohio, Class A CDL programs require a minimum of 80 hours of classroom, range, and road training, though many programs extend to 160 hours or more to ensure comprehensive skill development. Truck drivers are trained to expect the unexpected and adjust their driving accordingly.
In contrast, new drivers under 18 typically complete 24 hours of classroom instruction and 8 hours of behind-the-wheel training. This significant difference in training means truckers learn advanced skills like managing blind spots, handling large vehicle weight shifts, anticipating braking distances, and responding to unpredictable traffic conditions—areas that everyday drivers receive little to no training on.
By recognizing the rigorous training truckers undergo, everyday drivers can better appreciate the need for defensive driving. This awareness helps close the gap between professional and non-professional drivers, leading to safer roads for everyone.
With that in mind, let’s dive into four essential defensive driving rules truckers want every driver to know. These aren’t just common-sense tips—they’re crucial strategies that can help you avoid disaster and make the roads safer for everyone.
Rule #1: Stay Clear of ‘Dirty Air
Ever felt your car sway unexpectedly when passing a truck? That’s not just wind—it’s something truckers call ‘dirty air’—a powerful turbulence that can destabilize smaller vehicles.
When a truck moves at highway speeds, it displaces massive amounts of air, creating a wake of unpredictable forces behind and beside it. If you’re too close, this invisible force can pull your vehicle toward the truck or push it away, making it harder to control—especially for motorcycles and lightweight cars.
Why It Matters:
With more freight on the roads than ever, highways are getting more congested, and the risk of wind turbulence affecting passenger vehicles is increasing. Add in high-speed traffic and sudden lane changes, and you have a recipe for disaster.
How to Stay Safe:
✅ Don’t linger beside a truck. When passing, do so quickly but safely, and avoid staying in a truck’s side wake.
✅ Keep a safe following distance. The worst place to be? Right behind a truck, where you’re not only invisible to the driver but also trapped in the unstable air.
✅ Be cautious in high winds. Crosswinds can amplify a truck’s turbulence, making it even harder to maintain control.
At Alcoa® Wheels, we’re all about making the roads safer—because when trucks run smoothly, everyone benefits. As a leader in wheel innovation, we know that safer trucks mean fewer accidents, lower maintenance costs, and a more efficient transportation industry.
But safety isn’t just about strength and durability—it’s also about aerodynamics. Reducing drag and turbulence behind a truck doesn’t just improve fuel efficiency; it also enhances vehicle stability, helping drivers maintain better control on the road.
That’s why we develop aerodynamic wheel solutions that help direct airflow more efficiently, reducing turbulence and improving handling. Combined with lightweight aluminum wheels, which decrease overall vehicle weight and improve responsiveness, our innovations contribute to safer, more efficient fleets.
What’s the Lesson?
Next time you pass a truck on the highway, notice how your car reacts. If you feel it pulling or swaying, that’s your cue to give the truck more space. A little extra distance can mean the difference between a smooth ride and a sudden loss of control.
Rule #2: Air Brakes Aren’t Instant Brakes
Ever seen a car squeeze into a tight gap in front of a semi, then hit the brakes? That’s a disaster waiting to happen. Unlike passenger cars, trucks don’t use hydraulic brakes—they use air brakes, which take longer to engage. And when a fully loaded truck is rolling down the highway at 65 mph, it can take the length of two football fields to come to a complete stop.
According to the Federal Motor Carrier Safety Administration (FMCSA), this reaction time can add up to half a second before braking even begins. At highway speeds, that means a truck will travel an extra 47 feet before the brakes even engage.
Why It Matters:
With highways more congested than ever and stop-and-go traffic becoming the norm, giving trucks extra space isn’t just polite—it’s critical. Cutting too close in front of a truck reduces the driver’s reaction time, increasing the risk of a serious rear-end collision.
How to Stay Safe:
✅ Never cut off a truck. If you need to merge, make sure there’s ample space before moving over.
✅ Be mindful in traffic. If you see a slowdown ahead, start braking early so the truck behind you has time to react.
✅ Avoid brake-checking. Slamming your brakes in front of a semi can be deadly. Trucks simply can’t stop as quickly as you can.
At Alcoa® Wheels, we know that braking isn’t just about stopping power—it’s also about heat management. Excess heat buildup can reduce braking efficiency, leading to brake fade, longer stopping distances, and increased wear.
That’s where forged aluminum wheels make a difference. Unlike steel wheels, aluminum dissipates heat more efficiently, helping to keep brakes cooler under heavy loads and frequent stops. That means better performance, less risk of overheating, and longer brake life—critical for safety in stop-and-go traffic and high-speed braking situations.
This heat management advantage isn’t just about improving brake longevity—it directly impacts safety on the road, especially in high-traffic situations where every second counts.
What’s the Lesson?
The next time you’re on the highway, take a look in your rearview mirror before merging in front of a truck. If you wouldn’t feel comfortable with a truck that size tailgating you, don’t force the truck driver into that position. Give them the space they need to keep everyone safe.
Rule #3: Don’t Trust Your Eyes—Trucks Are Closer Than They Appear
At night, it’s easy to misjudge the speed and distance of a semi-truck. Truck headlights sit higher than those on a car, creating an optical illusion that makes them seem farther away and moving slower than they actually are.
Why It Matters:
According to the FMCSA, 40% of fatal crashes involving trucks happen at night. Many of these accidents occur when drivers pull out in front of a truck, misjudging how much time they have. Poor visibility, glare, and fatigue only make things worse.
How to Stay Safe:
✅ Double-check distances before merging. If you’re unsure, wait a few extra seconds.
✅ Be mindful of truck lighting. Reflective tape and marker lights are designed to improve visibility—use them to judge distance accurately.
✅ Avoid flashing high beams. Bright lights can momentarily blind a truck driver, reducing their ability to react quickly.
At Alcoa® Wheels, we don’t make headlights—we make wheels. But we do care about keeping every driver safer on the road. That’s why we’re shining a light on these critical driving tips (see what we did there?).

What’s the Lesson?
Next time you drive at night, take an extra moment to judge the speed of an approaching truck. A small miscalculation could mean the difference between a smooth merge and a deadly collision.
Rule #4: Rushing a Truck Pass Can Lead to a Crash
We get it—getting stuck behind a truck can be frustrating. But trying to speed past one recklessly can put you in serious danger. When two trucks pass each other, they create a slow-moving roadblock, and impatient drivers often try to squeeze through tight gaps or make last-minute lane changes. That’s a recipe for disaster.
Why It Matters:
Aggressive driving and sudden lane changes are leading causes of highway accidents. And with more trucks on the road, risky passing maneuvers are becoming increasingly dangerous. A little patience can go a long way.
How to Stay Safe:
✅ Wait for a clear opening. If you’re passing, do it safely and give yourself plenty of space.
✅ Don’t weave between trucks. Squeezing into a small gap increases your chances of a collision.
✅ Be mindful of speed differences. Trucks take longer to accelerate and decelerate—rushing a pass can leave you in a bad position.
We’re helping to solve this problem through lighter, more efficient wheels that keep traffic flowing safely and smoothly. Lighter trucks (equipped with Alcoa® Wheels) accelerate more quickly after lane changes and hill climbs, helping them get up to speed faster and reducing the time spent blocking lanes. This isn’t just good for truckers—it keeps traffic moving smoothly and lowers the risk of dangerous passing maneuvers. Plus, lighter wheels improve fuel economy and increase load capacity, making every mile safer and more efficient – that’s a win for everybody!
What’s the Lesson?
Next time you’re stuck behind a truck, take a deep breath and wait for the right moment to pass. A few extra seconds of patience can keep you—and everyone else on the road—safer.
