Traffic signal lights are part and parcel of what is utilized to make the roads safer and also more efficient for drivers. The thing is, though, the visibility of those traffic lights can be adversely affected by the height of vehicles, such as we see in semitrucks and, to a lesser extent, SUVs, for those who are driving in a sedan or other type of vehicle that is relatively low to the ground. So too, not all streets are perfectly level, which signifies that those streets that have traffic lights in which the driver is driving on an incline are going to be harder to see whenever they are behind vehicles that have a high footprint, and what needs to be taken into account, is that those that are unable to visually read the traffic light but take their clue that the light must still be green because tall vehicles in front of them are going through the traffic signal, are taking it by faith, that the light is still green, even though it may have turned red by the time that they have reached the intersection but because they have made that fateful decision they continue onward.
While critics could state that if a driver can’t see the signal then they need to leave more room between them and the vehicle(s) that is obstructing them, they don’t seem to recognize that semitrucks are so high, that the amount of room thus necessary to see the traffic light is going to leave a very large gap and hence will mean less traffic will get through the light than what would be anticipated. The better solution would be to engineer traffic lights so they are more visible, and the easiest way to do so is to make them higher than is typically the case in situations in which there is a preponderance of high vehicles, such as semitrucks, known to travel those roads.
No doubt, a higher traffic signal light would cost more money and would make that light conceivably more susceptible to high winds, but these are all engineering problems that would seem to have engineering solutions that are available to take advantage of. Indeed, any time that there is an accident at a traffic intersection, the reasons behind such an accident should be studied to see if anything could be done to reduce or prevent such accidents in the future. The bottom line is that traffic lights need to be visible and the more visible they are, by their illumination, by their height, or by their width, the safer it will be for those that travel those streets which should always be a serious consideration of communities that desire to see that traffic not only moves efficiently but is done so in a manner in which safety is taken into serious consideration, which is why especially on those streets in which semitrucks and other tall vehicles effectively block traffic lights from being readily read by sedans and the like, should be adjusted to take this into account.
