We are glad to send you the 9th INFO MANEJO's issue. Here you will find recommendations on how to overtake vehicles, advices on how to maintain tires in light vehicles and you will learn why it's useful to have tachographs controlling your fleets.

Manejo
    The overtake manoeuvre       First part
Distances perception

The overtake manoeuvre in two way traffic routes and with no central separation is one of the hardest and most dangerous ones. That is why, before doing it, it's better to considerate if it's worth it. In long or even in medium distance trips, it's recommendable to ponder how much time we would save and think if that reward it's worth it, bearing in mind the risk this manoeuvre implies. Therefore, when it's not convenient, we will not overtake cars in route.

One of the riskiest factors of this manoeuvre is the difficulty people have to estimate distances with our sight. Our size perception influences on the distance consideration to evaluate how far an object is, for example, a car that approaches. When we see it small, we think it's far away. If we see it bigger, we believe is closer. In short, our brain associates like this:
                                 SMALL --> FAR AWAY             BIG --> NEAR

Visual exercise:


This is why considerable mistakes occur, especially in routes where normally there are no references like in urban places.

Warning: Even if you an experienced driver, if you never drove a route or if you are in a place where you don't know the roads, bear in mind that your difficulties to calculate distances will be magnified. This can lead you to perceive wrong information about depth, size and, finally, the estimation might be incorrect in the eventual overtake. For this reason, for yours and the others safety, it's recommended to be accompanied by somebody experienced the first times you drive these routes so he help us comprehend the distances.

    Tire maintenance        First part
The word tire comes from the Greek word Neumáticos, related to a lung for the air that carries. The main function in the car is to allow a proper adherence and friction with the road, making possible to start the vehicle, to brake and the steering.

Its origin it's from 1888, when a Scottish surgeon and inventor, John Boyd Dunlop, inflated a rubber tube with an air pump, held it with a wheel rim and protected it with some canvas threads. Nowadays, modern technologies applied to tire manufacture make them a fundamental part for a vehicle's active safety.

Correct maintenance recommendations:

+ The four wheels should be well aligned; if not, there would be difficulties with the steering, a premature and irregular tire worn out and the driver would get tired.

+ Balance the tires when firstly placed and when they are dismantled for repair. They should be checked; if not there could be a tires early worn out and irregularities on the tread pattern, and all these affect the steering and suspension elements.

+ Maintain tires' air pressure (the spare one included) as the manual indicates. For this use a good quality -if possible, own- manometer. It's better to check the air pressure before running the wheels. With the correct air pressure, the tires last longer, you will save fuel, driving would be more comfortable and you will avoid risks.

Manejo
    24hs driving safely recording
Throughout the processes of evaluating and training drivers, the riskiest ones in front of the steering wheel are detected. As any evaluation, they are sporadic and specific. Between one and another, daily activity goes on with improvements, but always with the possibility of the occurrence of new deviations.

How can we control these deviations permanently?

Using a driving activities recorder, a Tachograph (electronic device installed in each vehicle), will allow us to register all kind of events. Then, with any software help, we can analyze automatically each driver's performance about the:


+ kilometres covered
+ speed limit excesses
+ sudden braking/ accelerations
+ vehicle's position (GPS)
+ driving speed in relation to the type of road

Nowadays, with this and some other information that is capable to be registered by these devices, we can detect the deviations that we set before as a goal.

However, the job doesn't end with installing and automatizing the information. The right management must be complemented with a correct reading and interpretation of the results, where a specialist takes part to help not only to detect the potential risks, but also to suggest proper corrective actions so the deviation doesn't occur anymore.

When the fleet is numerous, the main challenge is to systematize the reading, analysis and improvement so that the tacograph doesn't turn into a mere data collector.
