Sarcastic Secret: Signal Lights

By Chad Upton

Tickers, blinkers, indicators and flashers. They have many names, but only one purpose: to let people know your car is about to change course.

In most vehicles, a lever on the steering column moves up or down to activate flashing lights on either side of the car.

I suspect a lot of people don’t even know their car has such lights, but they’ve been standard on cars since cars.

Maybe it’s a confusing concept, so I’ll try to explain it in a straight forward manner: if you’re about to turn your steering wheel, put these lights on first.

I find that some people use signal lights like the horn. They know they’re there, but they only use them when they need you to move.

Most vehicles also have a way to put all four blinkers on at the same time. The vehicle manual may refer to these as “four way flashers” or “hazard lights” but a lot of people know these as “park anywhere lights.” Their understanding of this feature is, when you want to double park, park in a fire lane or any other no parking zone, these flashing lights give you temporary immunity from parking regulations.

In all seriousness, signal lights first appeared on cars in 1907, but weren’t patented until 1938. Some cars from the 1920s to 1950s used solid (non-blinking) retractable lights on the sides of the car, called a trafficators.

Understanding Trucker Signals

By Chad Upton | Editor

You can’t go far on the highway without seeing a semi-truck. While they may be intimidating to some, in many cases they are the most careful drivers on the road — their life and livelihood is on the line.

Truckers usually communicate with each other using citizen’s band (CB) radios, but they communicate with you using headlights, turn signals and trailer lights. In a lot of cases, you probably don’t realize they’re doing it.

Trucks have a lot of advantages over the average driver. For example, they sit a lot higher, so they see past other cars when you can’t. Also, from their CB radio, they know about things that are around the next corner.

The most common signal is used by cars and trucks in oncoming lanes. They will double-flash their headlights when they just passed a police speed trap that you’re heading toward. While this is very helpful, be sure you know your local laws about this, in some places it is against the law.

More than two consecutive flashes from oncoming traffic signals that there is another type of danger ahead, such as a foreign object on the road and drivers should proceed with caution. These two signals are often confused, but the appropriate action is the same, slow down. (more…)
