Check your lights!

Assume, for the moment, that you are one of those rare drivers who actually uses their turn signals (I’ll have more to say about that later). There’s not much point using them if they aren’t working, right? But how will you ever know if your lights are malfunctioning? You can’t see them from inside the car. Or can you?

In fact, most drivers have plenty of opportunities to check their lights, if they could be bothered to notice. Next time you park, pull up close to whatever is in front of you and check your headlights. Even if it’s daylight, you should be able to see clearly if they’re both working. Then do the same thing for your turn signals.

Checking your rear lights is a bit trickier, but still doable. Next time you’re stuck in bumper-to-bumper traffic, take the car out of gear and tap the brake pedal a few times. You should be able to see them in the rear view mirror, lighting up (or reflecting off) the vehicle behind you. Your results will vary, depending on the positioning of your lights and the type and colour of the vehicle behind you. Do the same thing for the rear signal lights, but be careful: you don’t want to give the impression that you want to change lanes.

It’s best to do these checks in your driveway or in stopped traffic. Don’t fiddle with your signal lights in moving traffic. That’s dangerous.

There are sensors under the pavement, dummy!

In my home town, and probably many others in North America, there are now sensors under the pavement at an increasing number of intersections. The sensors detect the presence of vehicles and affect the traffic light cycle at that intersection. You can often see where the sensors have been embedded, as the process leaves circular or rectangular patterns where the cuts are made. The sensors are commonly used where less-traveled roads intersect a major road. This effectively creates an on-demand system, where the light cycle shortens to give a green light to the less-used road when vehicles are waiting there. This makes a lot of sense: there’s no point interrupting flow on a major road when there are no cars waiting on the other road. The sensors are used in plenty of other situations. In left turn lanes, they trigger an advanced green. At busy intersections, they can help to optimize modify the light cycle throughout the day. They can be placed farther from the intersection to kick in when more than a certain number of cars are waiting. And so on.

Surprisingly, many drivers either aren’t aware of these sensors or they are just too dumb to cope with them properly. A few months ago I was at an intersection equipped with on-demand sensors. I was the second car waiting at a red. I noticed immediately that the first car was too far back to trigger the sensor, and sure enough, a complete light cycle went by and we never got a green light. The opposite side got an advance and a regular green, but we never did. I got out of the car, tapped on the driver’s window and explained to the driver that she needed to pull up. She did so and we got the next light. Of course, I’ll never know if she really believed me. She might have thought I was a nutcase and we got the green because it was (eventually) our due. Sigh.

If you’re observant enough to notice the sensors, you can even tweak them to your advantage, with a little experimentation. Near my home there are sensors in a left turn lane that I use regularly. I recently noticed that there are sensors at the front of the lane, and about three cars back. I discovered that the advance green doesn’t kick in unless there is a car sitting on the sensor that’s farther back, so I played around with it. I found that if I triggered the front sensor, then backed up and sat on the other sensor, it would trigger the advance. That’s not usually practical and it could be dangerous, so I don’t try that unless the road is fairly clear in my direction. But if I’m the second car in the turn lane, I don’t pull up behind the first car, I stay back and sit on the back sensor, triggering the advance. Fun, and useful!

Driving me crazy. This is how I feel about the drivers I share the road with every day. What makes me crazy is that much of their poor driving is completely avoidable. Assuming that they give a crap about anyone other than themselves, all they need to do is pay attention… be aware of what’s happening around them. Realize and admit their failings and learn from their mistakes. It’s what I do, and I think it’s made me a better driver.
