Along the Spanish roads there is a lot signaling, objects, beacons and more instruments that help us have a safe driving at all times.
One of them is the lines that delimit your lane. And is that, In addition to separating the senses or the number of lanes in the same direction, they have an application that you did not know and that helps in driving.
These are sound bands or sound guides. According to the General Directorate of Traffic “a sound guide arranged in the longitudinal direction of the road is constituted by a series of fresh elements destined to alert (through vibration and sound), to drivers who suffer a distractionthat your vehicle is deviating from the trajectory of the lane.
Why do the white lines sound on the road when you step on them?
A team professional @Motorpasión Explain that “Sound bands serve to let you know when you’re getting out of the lane. But the best thing is that they were invented for something else. They are called sound bands and when you step on them make the wheels of the car vibrate and make a very characteristic noise“
In addition, he adds that “this has to do with how they are done. There are two types: Some are some plastic bars that stick very strong to the road; And there is Other soundtracks that are directly frequent on the asphalt With a milling machine. “
“Initially the idea was that they served to improve the night visibility of the roads when it rains. So that these reflective bars were above the water when it rains and that way the limits of the road perfectly are seen. “
“After trying them they discovered that when they tread them they made a certain sound and emitted a vibration behind the wheel. And that is why, today they are used on many roads due to how good it is at the security level, both for visibility when it rains, as well as the warning when you are going out of the lane. “
Are they really reliable?
According to various investigations cited by the General Directorate of Trafficsoundtracks They reduce between 38% and 50% accidents with victims on unique and double direction roads.
Thanks to the sound and vibratory alert, it helps drivers perceive quickly to the situation of danger or that he can fall asleep and get out of the lane itself.
You have to remember that Being asleep at the wheel is a significant cause of traffic accidents, representing between 15% and 30% of the accidents in Spain. Drowsiness negatively affects driving capacity, reducing reflexes and reaction capacity, which can lead to dangerous situations such as getting out of the road but that with the help of these bands is minimized as much as possible.
