“Ever been on the freeway, cruising along, when suddenly you see brake lights ahead? Your instinct? Hit the brakes. But what if I told you that reaction—one we’ve all had—could be part of the problem, not the solution?
Hey everyone, I’m Randy Keith, and welcome back to Mastering the Commute. Today, we’re tackling something every driver experiences: brake lights, red lights, and traffic flow. This podcast is all about seeing traffic differently—not just reacting to it, but understanding how it works so you can drive smarter.
The key? Traffic moves in waves. But most drivers don’t think about that when they slam the brakes or hit the gas. Today, we’ll break down what’s happening on the road beyond just your car—because once you start seeing the bigger picture, you’ll realize just how much control you actually have over your own commute.”

Key Point 1: The Ripple Effect of Sudden Braking
“When you see brake lights ahead, your natural instinct is to slow down. That’s fine—but how you slow down makes all the difference.
One sharp brake can cause a chain reaction. Even if you stop in time, the person behind you might slam their brakes harder, and then the person behind them even more. This creates what traffic engineers call shockwaves—a ripple effect that can last for miles.
I saw this all the time when I was reporting from the air over LA’s freeways. One car would tap the brakes, and within seconds, a domino effect would spread five, ten, twenty cars back. This is why traffic can come to a stop with no accident in sight.
So how do you avoid contributing to the problem?
• Look beyond just the car in front of you. Scan at least 5-10 cars ahead to anticipate slowdowns.
• Ease off the gas early instead of waiting until the last second to brake.
• Leave space so you can adjust your speed smoothly—this keeps traffic moving instead of stopping and starting.”

Key Point 2: The Fast Lane vs. The Constant Speed Lane
“Here’s where things get interesting. You might think the fast lane moves the quickest, right? But have you ever noticed that when traffic gets bad, some lanes stop and start, while others keep moving?
It’s all about constant speed driving.
• The stop-and-go lane looks faster because cars dart forward when there’s a gap—but then they slam on the brakes again.
• The constant speed lane might seem slower at first, but it actually flows more smoothly over time.
Think of it like a river. If you pour water into a bottle too fast, it splashes back. But if you pour steadily, the flow remains constant. Traffic works the same way.
And I get it—sometimes, keeping a steady speed frustrates people behind you or even in your passenger seat. But here’s the thing: When traffic starts moving again, the steady speed lane wins. Every time.
This is something we’ll break down even further in a future episode, but for now, just try this out:
• Instead of rushing into gaps, keep a steady pace and see how it feels.
• Watch the traffic waves ahead and avoid needless braking.

Key Point 3: Green Light Anticipation – Why It Matters
“We’ve spent a lot of time talking about brake lights, but let’s talk about green lights for a second—because this is where drivers waste a ton of time.
How many times have you been stuck behind someone who wasn’t paying attention when the light turned green?
This is a problem because:
1. Every second at a green light adds up. Even a one-second delay per car can waste minutes across an entire intersection.
2. Hesitation slows everyone down. The more people creep forward instead of accelerating smoothly, the longer the backup stays in place.
3. Phone distractions make it worse. When someone checks their phone at a red light, they’re late to accelerate—which compounds delays.
Now, I’m not saying you should floor it the second the light turns green, but being ready to move is a major key to keeping traffic flowing.”

Final Thought & Call to Action
“So here’s the takeaway:
• Traffic moves in waves.
• Sudden braking creates unnecessary slowdowns.
• Keeping a constant speed is more effective than chasing gaps.
• And being ready when the light turns green saves time for everyone.
Next time you’re on the road, try this out:
• Notice how traffic reacts when someone brakes suddenly versus when they slow down gradually.
• Try keeping a steady speed, even if it feels counterintuitive.
• And when you’re at a red light, be ready to go the second it turns green.
