We are glad to send you the 27th INFO MANEJO's issue. Today you will learn about the dangerous modifications to heavy vehicles and on how to cross joints safely.

We also invite you to visit our new web site where you will find previous INFO MANEJO issues, in their Spanish and English versions.

    Driving and distraction
Using cell phones

Distraction represents between 30 and 40 percentage of the accidents, according to different studies done in Holland, England and Spain. One of the most common ways of distraction is by using cell phones while driving, and the driver might show it through two ways:

+ Physical distraction: for example, when the driver has to dial a number, answer a phone call and hang up, and at the same time, drive the vehicle.

+ Cognitive distraction: when we divert part of our attention in order to talk on a phone conversation, when our attention must be focused on driving.

We must know that our skills are limited when we divide our attention between different simultaneous tasks, and using cell phones when driving produce a negative effect on the driver's performance, with a hidden risk -checked by the RACC Automóvil Club de España- talking over cell phones while driving increases up to four times the chances of being involved in an accident.

Investigations performed in a driving simulator at the Utah University Applied Cognition Laboratory prove that talking over the cell phones affects in a significant manner the driver's performance. Talking over the phone produces an attentional blindness, causing negative consequences over common driving reactions: braking and decelerating the vehicle. While we talk over the cell phone, our reactions will be much slower than when we are not in a phone conversation.

In fact, conversing diverts our attention and conditions the perceptual information process skills. This type of distractions make drivers miss or misunderstand a traffic sign, because their capacity of detecting, distinguishing and answering to different visual stimuli, even when we -wrongly- think that talking over the phone only affects our ears-.

It is argued against the prohibition of using cell phones while driving, that having a conversation with other passengers in the vehicle produces the same effect as talking over the phone. Actually, a simple conversation with other passengers just demands a low level of concentration, and it does not produce a significant interference. But, a conversation over the phone is a more complex situation, because it makes us "go out of the scene" and it influences on the attentional level, leading to distraction. So we can infer that using a hands free device is as dangerous as using the actual cell phone. In this last situation, there are added tasks: answering the phone, holding it, and hanging up -physical distraction- which diminishes our attention performance, vital part of a driving safely.

The intelligent driver respects the law as regards phone usage while driving, due to the understanding of the dangerous distractions.

    Common transmission failures
Transmission systems are designed to supports big loads and high torsion resistance. The current quality levels cause that the failures are only related to a bad usage or an inadequate maintenance, and can be summarized in a common factor: excessive or uneven wear of the surfaces in contact.

As they are "silent" mechanisms, the first symptom appears when the gears start making noises.

Training drivers properly will allow them to detect the area that is failing because as soon as they hear it, they can identify the type of sound and prevent expensive breakages and vehicle breaking down in routes.

If we follow these simple recommendations, we will help prevent and avoid future problems:

+   Start the vehicle and accelerate with the straight wheels, brake and turn in a non sudden way.
+   Do not overload the vehicle.
+   Apply rigorously a preventive maintenance plan.
+   Use only the manufacturer indicated lubricant. If not obtained, use another also authorized, but superior.
+   Periodically control the levels, even when there are not visible leaks. Levels can descend due to other causes, such as evaporation or passing to another compartment due to broken parts.
+   For periodic changes, check thoroughly the lubricating oil which was used, in order to detect contamination or metal parts that might cause premature wear or breakages.
