We are accustomed to the fact that the topic of limited visibility comes up consciously only in the theoretical part of the traffic rules exam – traditionally in the difference between limited and insufficient visibility. In ordinary life, we do not attach much importance to this, well, it is not visible and not visible, what can we do? Let’s talk about the danger of limited visibility, what is it and what to do about it?
What is limited visibility?
We open the traffic rules, read. Limited visibility is any clipping of visibility created by physical obstacles, permanent (terrain, geometry of the road, houses, exits from yards, tunnels) or temporary, stopped by large vehicles, for example.
One way or another, the rules say that limited visibility depends primarily on objects that do not provide a high-quality view and who is trying to get this view within a radius of 100-150m. We, as drivers, simply state the fact that a certain object N blocks the view of the carriageway and do not react to the situation with the awareness “here I have entered a zone of limited visibility, I will be more attentive and slow down”, although we are fully aware of the zone of insufficient visibility: we have entered fog, rain, dusk. Because of this, the situation is trite underestimated.
What is the danger of an area with limited visibility?
I would not have touched a similar topic if it were not for the terrible and sometimes just stupid accidents. Just the other day, in my city, a driver in an old jikser hit a child to death. He saw people getting out on the zebra crossing, saw a car letting pedestrians pass ahead of him. The motorcyclist decided that the bike was faster and it would pass the pedestrian crossing even before people reached the passing car on the right side of the lane (the “jikser” itself was driving along the left edge of the same lane). The motorcyclist did not see that a six-year-old girl was already running in front of the car. The body blocked his view.
A huge number of accidents occur due to limited visibility, when another car obstructs the field of view, when they cannot see you or you cannot see. Traffic accidents are like in the day of a groundhog – they will repeat themselves according to the pattern, at intersections they demolish motorcyclists who drive straight out of the aisle, and the car finishes a turn maneuver and does not assume that a motorcycle is racing after another car. His view is limited. Like yours.
Departures from the courtyards – another Narnia on the streets of the city. How often are buildings or arches obstructing the view?
Limited visibility on steep bends results in collisions when one of the participants chose a trajectory too close to the center of the turn. Classic: Crash on a bend with oversized vehicles. The motorcycle turns around, but to the meeting the truck, the cabin of which turns smoothly, but the trailer does not. The trailer, by the way, also blows away on wet asphalt at sharp turns, deviates from the original trajectory in a crosswind, rearranging it to the adjacent lane. At a high turning speed, the trailer begins to move diagonally at all, especially noticeable in really long trailers and road trains. And at a sharp turn, you did not expect to see each other, although both knew that the turn limits visibility, which is equivalent to opening the Pandora’s box.
- Due to limited visibility, there is no correct assessment of the traffic situation.
- You may not see pedestrians or other vehicles.
- Other road users may not be aware of your presence as you are in a reduced visibility / blind spot.
- You risk getting into an accident due to the condition of the road after the blind spot, lack of time and space to react to the situation.
- If you leave your vehicle in a place with limited visibility, other road users may crash into it.
Remember to check if your motorcycle is obstructing other road users.
What to do in low visibility conditions?
- Reduce the speed to the minimum allowed.
- Break the distance.
- Reduce the number of maneuvers, do not overtake or turn around.
- Do not leave vehicles in the parking lot and do not make stops in the limited visibility zone.
As Professor Preobrazhensky used to say: she is in ruin in their heads. Problem solving is in them. If you know that the place is limited by a visual overview, then why maneuver there again? Traffic rules prohibit overtaking and turning in places where visibility is less than 100m. The highest point of the climbs is also considered to be an area with limited visibility.
Reducing speed and increasing distance, lateral spacing is recommended as a backup airbag for an emergency. Emergency clearance. Silly accidents, when, instead of stopping or slowing down, the motorcyclist decides to slip by, not thinking that he may not be seen, or he calculates the equation with unknown participants who are hiding in the blind spot.
Ripping lateral spacing and distance can save the rider. How often, when driving in the aisle, do you turn along the inner radius, and parallel to you, the car turns suspiciously close? He closes you, you do not see other cars and pedestrians behind him, you partially find yourself in the blind zone with him, and someone is sure to lose at this roulette at least once. Never make a parallel turn with other traffic in the stream, while in the inner radius, especially with a large trailer! They do not see you, you risk being overturned or squeezed. Diving inside a turn with the trailer of another car or truck is generally a desperate method of suicide.
In other words, with limited visibility inside the city, you should not accelerate or turn around. It is not necessary to make maneuvers when you are not sure of the circumstances.
