Today I want to talk about a change in driver’s habits that I’ve seen changing over the last five years. The change is in drivers helping other drivers make lane changes.
You are driving on a four-lane highway. The truck ahead of you is running slower than you. You signal and pull over into the “hammer lane.” As you pull ahead of the slower truck, the driver of the slower truck briefly turns off his headlights when it is safe to make the lane change back to the right lane.
Then, as you move over or after you are back in the right lane, you either put on the four-ways or blink your running lights as a way of saying, “thanks for your help.”
At night the “standard” was for the slower driver to briefly turn his headlights off. During the day, the slower driver would turn his headlights on, if they were off. If they were running with the headlights on, they would either briefly turn them off or flash the high beams.
In 2005, this happened 98% of the time one truck passed another. It was just one of the standard courtesies of the road that professional drivers extended to other professional drivers.
Changes on the Highway
Over the past couple of years, I see fewer and fewer drivers using the headlights and running lights to help other drivers. If I had to venture a guess, this only happens 60% to 65% of the time.
The other negative change I’m seeing is at night. In 2005, I would never see the slower driver flash the high beams at night to signal the faster driver it was now safe to change lanes. Sure, some four-wheelers would do it out of ignorance, not knowing they should flick the headlights off. Or, if they did, were afraid of not being able to see that brief moment the headlights were off.
But, professional drivers never used their high beams to signal at night because they knew the faster driver would be looking at the mirrors. And they knew that using a high-beam signal was unpleasant (at best), or dangerous (at worst) as it diminishes night vision.
The first time I passed a Big Truck at night and the driver flashed his high-beams to signal that it was OK to change lanes I was surprised and angered that a professional driver would to that to another professional driver! My reaction is still surprise and anger when it happens now. Some of my anger comes from the temporary night blindness that always follows afterwards.
If you are a driver who does this, please don’t use your high beams at night to signal it is safe for me to change lanes. If you don’t feel safe turning your headlights off briefly to signal, either don’t signal or flash your running lights. The purpose of signaling is to help the faster driver make a SAFE lane change. During the day, sure, go ahead and flash the high beams. I don’t mind a bit.
Why?
I asked myself why the change in the way professional drivers use their lights to signal lane changes. So, I decided to do some research to see if I could come up with reasons for why these changes are occurring.
It’s Taught in Driving Schools.
I found out that some driving schools are teaching students to signal with high beams! This caught me off guard because I couldn't believe that a school would actually be teaching an unsafe practice! The instructors teaching this probably haven’t actually driven and are teaching out of textbooks instead of from actual experience on the road!
Perhaps this is an example of, “Those who can, do. Those who can’t, teach?” If you are an instructor teaching foolishness like this, please spend a couple of nights on Donner passing some of your students. One or two nights like that will change you forever. Assuming you survive, of course.
Cell Phones
Some states now have laws making it illegal to use a cell phone while driving. Or, they require drivers using cell phones to use a headset or other “hands-free” device. I’ve noticed more professional drivers using cell phones in these states than before the law was passed! Maybe they figure they are “above it all?”
The odds of getting a “safe to change lane” signal from a driver holding a cell phone to their ear after passing them is pretty low. Are you trying to reach that light switch with your knee?
A recent study shows that head set or not, using a cell phone while driving significantly increases response time in emergencies. It’s not about having both hands free; it’s more about what's going on inside the head that is controlling the hands. It’s like having twenty programs open on your computer and wondering why it is running slowly.
I Didn’t Know.
More drivers are going straight from school to the road with no Mentor Program. Driving schools do a great job at one thing. Getting the student ready to pass the state CDL exam. If it is not on the exam, it isn’t taught. As a result, new drivers with fresh a CDL are given keys to a tractor and let loose in the highway without the benefit of driving with an experienced driver.
More foreign nationals who bring their culture with them are now driving commercial vehicles. Many of them were professional drivers and bring the driving culture from home as well as language, diet and clothing preferences.
I Don’t Care Anymore.
I’m convinced that many seasoned drivers are frustrated. I know that I’m tempted not to signal at times when I pass and the driver doesn’t signal a safe lane change.
I made a decision, to flash the running lights even when I don’t see the driver signal a safe lane change. Why? First, I might have missed the signal. I’m not perfect and may have missed seeing the signal. Second, I don’t want to get in the habit of not flashing. Third, I hope that flashing will encourage the “I didn’t know” drivers to pick up the habit of courtesy. Monkey see, monkey do.
If you are one of the “I Don’t Care Anymore,” drivers, I encourage you to get back in the habit of signaling safe lane change to drivers passing you and flashing a “thank you” to drivers you are passing. If you are opting out because some other drivers aren’t reciprocating, you are actively contributing to this problem.
Be a Teacher.
The best way to lead or to teach is by example. Make sure that what you do “out there” is the best it can be because someone is always watching and learning from your examples.
