Slow Is Fast

By About a 7-minute read

One of the accomplishments I am most proud of during my 25-year career in trucking and logistics is my safety record. During that time, I have been involved in only two accidents, and I was not at fault in either one.

I do not believe that record is simply the result of luck. It comes from habits I have practiced consistently—controlling my speed, maintaining space, looking far ahead, and refusing to let traffic pressure determine how I operate the truck.

I normally drive at or below the speed limit. Some drivers may consider that too cautious. Others believe that every available minute must be recovered by driving faster.

My experience has taught me the opposite.

When you operate a commercial vehicle smoothly, patiently, and at a controlled speed, slow becomes fast.

What “Slow” Really Means

Driving slowly does not mean obstructing traffic, traveling unnecessarily far below the speed limit, or ignoring the normal flow of the road.

It means selecting a legal speed that is appropriate for the truck, its weight, traffic, weather, visibility, road conditions, and available stopping distance. It also means maintaining that speed as consistently as conditions allow.

The speed limit is the maximum under favorable conditions. It is not a promise that the posted speed is always safe. Rain, fog, curves, work zones, congestion, heavy loads, and limited visibility may require a lower speed.

FMCSA reminds commercial drivers that higher speeds increase perception-reaction distance, braking distance, and total stopping distance. A loaded commercial vehicle already requires substantially more room to stop than a passenger vehicle.

Driving a little slower gives me something extremely valuable: time.

Time to see a developing problem. Time to understand it. Time to decide what to do. Time to slow down without making an emergency maneuver.

The Smith System Changed How I Drive

I learned about the Smith System more than 20 years ago while training to obtain my CDL. I thought it was an intelligent and practical system, and I began applying it to my everyday driving.

I still use it today.

The Smith System is organized around five principles: aim high in steering, get the big picture, keep your eyes moving, leave yourself an out, and make sure other road users see you. Together, they emphasize visibility, space, awareness, and time.

For me, these principles are not phrases that belong only in a training classroom. They influence how I approach every intersection, lane change, curve, construction zone, and traffic slowdown.

Looking far ahead helps me see brake lights and traffic signals before I reach them. Getting the big picture helps me recognize what vehicles beside and behind me may do. Keeping my eyes moving prevents me from concentrating on only one hazard. Leaving myself an out keeps me from becoming trapped. Making sure others see me helps reduce surprises.

Speed control supports every one of those principles.

I Do Not Race Toward Red Lights

One of the best examples happens when I approach a traffic signal.

Many drivers maintain their speed until they are close to a red light and then brake hard. After stopping, they accelerate again to move thousands of pounds from a standstill.

I prefer to look far ahead. When I see stopped traffic or a red light, I release the accelerator early and allow the truck to slow gradually when it is safe to do so.

Frequently, the light changes before I arrive. Traffic begins moving, and I can continue without bringing the truck to a complete stop.

That does not happen every time. I never delay other vehicles or assume that a light will change. I remain prepared to stop.

The advantage is that I am responding to what I can see ahead instead of racing toward a condition that already requires me to slow down.

Starting a heavy truck from a complete stop requires considerably more energy than maintaining controlled momentum. Frequent acceleration, braking, speeding, and unnecessary shifting reduce fuel economy. The U.S. Department of Energy recommends smooth acceleration and braking as fuel-conservation practices.

Every unnecessary hard stop wastes momentum. Every aggressive restart consumes additional fuel and adds wear to the equipment.

Let the Traffic Move Ahead

When I drive slightly below the maximum speed, faster traffic normally moves ahead of me.

I consider that an advantage.

Instead of constantly fighting for position, changing lanes, passing vehicles, and traveling inside groups of traffic, I allow those groups to move away. The space that develops in front of my truck becomes a safety cushion.

That cushion gives me better visibility and more room to respond when somebody brakes suddenly, changes lanes without enough space, misses an exit, or makes an unpredictable decision.

This does not mean remaining in an inappropriate lane or forcing other motorists to pass dangerously. A professional driver should use the correct lane, respect minimum-speed laws where applicable, and avoid creating an unnecessary obstruction.

The purpose is not to control everybody else. The purpose is to protect the space around the truck.

Smooth Driving Protects Fuel and Equipment

A commercial vehicle consumes a great deal of energy when accelerating. Speed also increases aerodynamic resistance, meaning the engine must work harder to maintain higher highway speeds.

Government fuel-efficiency guidance identifies speeding, aggressive acceleration, and frequent braking as behaviors that reduce fuel economy.

A smooth driver can reduce unnecessary fuel consumption, hard-braking events, tire and brake wear, repeated gear changes, sudden cargo movement, stress on the engine and drivetrain, and risks created by abrupt maneuvers.

One aggressive acceleration may not seem important. Repeating it at every traffic signal, entrance ramp, slowdown, and lane change throughout an entire career is different.

Professionalism is built through thousands of small decisions.

Driving Faster Does Not Guarantee Arriving Sooner

We need to be honest: reducing speed can add some driving time over a long, uninterrupted distance. “Slow is fast” should not be interpreted as a mathematical claim that a lower speed always produces a shorter trip.

The real lesson is that speed alone does not determine whether a driver arrives on time.

Trip planning, departure time, traffic, construction, parking, fuel stops, loading delays, weather, and hours of service can affect a schedule more than a few additional miles per hour.

A driver who leaves late cannot safely repair the schedule with the accelerator.

Speeding may recover a few minutes, but a traffic stop, preventable collision, missed exit, mechanical problem, hard-braking event, or additional fuel stop can eliminate those minutes immediately.

My objective is not to win every mile. It is to complete the entire trip safely and predictably.

Controlled Driving Reduces Stress

When I stopped treating traffic like a competition, driving became less stressful.

I do not need to defend every space. I do not need to accelerate because another driver passes me. I do not need to follow closely because someone entered my lane. I can restore the space and continue working.

That mindset changes the job.

Driving calmly allows me to observe instead of reacting emotionally. It reduces unnecessary braking, lane changes, frustration, and confrontations with other motorists.

I cannot control traffic. I can control the speed, space, and decisions inside my truck.

My Record Was Created One Trip at a Time

I am proud of my safety record: only two accidents during a 25-year career, with neither one being my fault. However, I do not treat that record as a guarantee.

The next trip still requires my full attention.

Experience does not make a driver immune to mistakes. In fact, becoming overconfident can destroy a good safety record very quickly.

That is why I continue applying the same principles I learned more than two decades ago.

Look far ahead. Maintain space. Keep your eyes moving. Protect an escape route. Make yourself visible. Control the speed before the situation controls you.

Slow is not weak, fearful, or unprofessional.

Slow is deliberate. Slow is prepared. Slow preserves fuel, equipment, energy, and reaction time.

The fastest trip is not the one completed at the highest speed. It is the one completed safely, without unnecessary stops, preventable incidents, or decisions that place the driver and everyone around the truck in danger. That is what “slow is fast” means to me.
