White and yellow lines are used along pavement edges and between lanes to keep vehicles in line. These lines may be solid or broken (long dashes), single or double.

At many highway-rail crossings, the crossbuck has flashing red lights and bells. When the lights begin to flash, stop! A train is approaching. DO NOT STOP ON THE TRACKS OR WITHIN SIX FEET OF EITHER RAIL. Do not move forward until you can do so safely. If there is more than one track, make sure all tracks are clear before crossing. In heavy traffic make sure there is room for your vehicle on the other side before starting to cross.

OCTAGON: Exclusively for stop signs. HORIZONTAL RECTANGLE: Generally for guide signs. TRIANGLE: Exclusively for yield signs. PENNANT: Advance warning of no passing zones.

The lane marking arrow, in the center lane in the diagram below, indicates that traffic in this lane can be reversed in accordance with local traffic controls due to "rush hour" traffic or other special traffic conditions.

Any pedestrian or person driving a vehicle and approaching a railroad highway grade crossing must stop within 50 feet but not less than 15 feet from the nearest rail of the the railroad when the electrical or mechanical warning devices are flashing, the crossing gate is lowered, a human flagger is warning of an approaching train, or an approaching train is clearly visible and is in close proximity to the railroad highway grade crossing. Do not proceed until you can do so safely.

This sign is used on multiple lane highways to advise slower driving traffic to stay in the right hand lane; and also to do so when approached from behind by other traffic even if you are doing the speed limit.

A diamond-shaped marking shows that a lane is reserved for certain purposes or certain vehicles. The lanes are usually reserved for buses or car-pool vehicles during rush hour traffic. Other diamond signs are used to designate bicycle lanes.

If there is no marked stop line, stop before entering the crosswalk on the near side of the intersection. If there is no crosswalk, stop at a point nearest the intersecting roadway where you have a clear view of approaching traffic on the intersecting roadway before entering the intersection.

This sign lists the maximum recommended safe speed for an entrance or exit on an expressway. Slow down to whatever speed is shown.

Many people wonder if police drones measure speed. The answer to this question may be surprising - although in theory it would be possible by using high-resolution cameras and taking image-based measurements, in practice, a police drone is rarely used for this purpose. However, this does not mean that such devices are not used in traffic control. The police drone can be used to identify various offenses, such as unsafe maneuvers, overtaking on bans or running red lights. The tasks carried out by drones therefore focus more on providing evidence - which in turn can be used for further investigation or sanctions.

Go — but only if the intersection is clear. Yield to pedestrians and vehicles still in the intersection. If turning left, wait for gap in oncoming traffic to complete turn.

Flashing arrow panels are used both during the day and at night to give advance warning and directional information to drivers where it is necessary to move to the right or to the left into another lane.

There are eight shapes and eight colors of traffic signs. Each shape and each color has an exact meaning, so you must acquaint yourself with all of them.

What a police drone looks like? Most devices of this type present themselves similar to commercial drones, however, they are noticeably larger. The type of camera used is also an important differentiator - a police drone must be able to record events from a distance, which is why wy use lenses with up to 30x optical zoom and 180x digital zoom. Selected models may also be equipped with specialized GPS systems or additional propellers to ensure stable flight in difficult weather conditions.

Drones are now used in many fields - including law enforcement operations. They are used by m.in. police, both in Poland and in other countries. What a police drone is used for, what capabilities it provides and what you should know about it?

Trains cannot stop quickly. An average freight train traveling at 30 MPH needs a stopping distance of more than half a mile. Longer trains moving at faster speeds can take one and a half miles or more to stop.

Come to a complete stop at the marked stop line or before moving into the crosswalk or intersection. After stopping, you may turn right on red arrow at most intersections if the way is clear. Some intersections display a "NO TURN ON RED" sign, which you must obey. Left turns on red arrow from a one-way street into a one-way street are also allowed.

There are several signs, signals and pavement markings that indicate highway railroad crossings. When you see one of them, slow down and be ready to stop.

Blue and white signs direct you to services, such as gas, food, motels and hospitals. Brown and white signs point out scenic areas and parks.

Grooved pavementsignmeaning

Due to its ability to move quickly through the air, the police drone can provide images from any location, monitoring large areas in a short period of time. Services can also use such data m.in. for patrolling dangerous areas where the risk to officers is too high. All of this means that the police drone provides a range of new capabilities for the police, mainly centered around supporting operations in challenging conditions.

A green arrow, pointing right or left, means you may make a turn in the direction of the arrow. If the red light is burning at the same time, you must be in the proper lane for such a turn, and you must yield the right-of-way to vehicles and pedestrians within the intersection.

The advance warning sign is usually the first sign you see when approaching a highway-rail intersection. The advance warning sign advises you to slow down, look, and listen for a train, and be prepared to stop if a train is approaching.

It is worth noting that a police drone is a device equipped with advanced cameras, often with much better performance than in commercial drones. This allows the devices to capture high-quality images in real time - both during the day and at night. Importantly, a number of special technical solutions are also used in the area of service support. For example, a police drone at night can be equipped with night vision and thermal imaging technology, allowing effective monitoring even in conditions of limited visibility.

What doesthissign mean

Barricades, vertical panels, drums, and cones are the most commonly used devices to alert drivers of unusual or potentially dangerous conditions in highway and street work zones. These devices are used to guide the drivers safely through the work area, and at night, they may be equipped with warning lights. When a Road Closed sign is displayed, do not drive on this road. Look for a detour or another route.

Stop if you can. The light will soon be red. The yellow arrow means the same as the yellow light, but applies only to movement in the direction of the arrow.

As you approach this sign, slow down, watch for children crossing the road. Stop if necessary. Obey signals from any crossing guards.

Crossbuck signs are found at highway-rail intersections. They are yield signs. You are legally required to yield the right of way to trains. Slow down, look and listen for a train, and stop if a train approaches. When the road crosses over more than one set of tracks, a sign below the crossbuck will indicate the number of tracks.

SLOW MOVING VEHICLE Vehicles going less than 25 miles per hour (such as farm equipment) must display this sign on the rear when using public highways.

The range offered by a police drone depends on several factors - the most important issues are the design of the device and the technical solutions used. In Poland, drones with a range of a few kilometers (usually approx. 2 km), allowing effective monitoring of different areas. In addition, police drones are often characterized by the ability to operate at fairly high altitudes (even up to several hundred meters), providing a better view of a given location. Also an important piece of equipment are night vision and thermal imaging cameras, that allow you to maintain visibility at night.

Construction and maintenance signs are used to notify drivers of unusual or potentially dangerous conditions in or near work areas. Most signs used in highway and street work areas are diamond shaped.

At the intersection ahead traffic in left lane must turn left and traffic in adjoining lane may turn left or continue straight ahead.

Slow down and give vehicles crossing your path the right-of-way. If the way is clear, you may move forward slowly without stopping. Yield signs are usually placed where auxiliary roads lead into major roads.

Pavement markings, consisting of an RXR followed by a stop line closer to the tracks, may be painted on the paved approach to a crossing. Any person walking or driving a vehicle must stop within 50 feet but not less than 15 feet of the crossing. Stay behind the stop line while waiting for a train to pass.

Importantly, the police drone can be connected to other speed control systems. It is also worth noting that police drones are subject to the same regulations as other recording devices, such as speed cameras. This means that the police drone and the data it collects (in particular - the recorded image) can be the basis for issuing a traffic ticket.

It's also worth knowing what a police drone looks like at night. How to spot a police drone at night? Such devices can be difficult to spot, especially when operating at a considerable height. Police drones at night, however, can be recognized by their the use of lighting to keep them safe while flying in low-visibility conditions. Mostly these are LEDs. Sometimes they can be turned off - this occurs during operations that require hiding the drone's presence. In addition to the light positioning lights, the police drone can also be recognized by the distinctive sound of spinning propellers, which can be heard from several meters away.

A flashing red light means the same thing as a stop sign. It is used at dangerous intersections. A flashing yellow light means you may move forward with caution. It is used at or just before dangerous intersections, or to alert you to a warning sign such as a school crossing or sharp curve.

Dipin the road meaning in urdu

Two-way roadway with a center lane for left turns in either direction of travel. The specially marked center turn lane is intended for slowing down and for sheltering of turning vehicles and may not be used for passing.

A four-way stop sign means that there are four stop signs at this intersection. Traffic from all four directions must stop. The first vehicle to reach the intersection should move forward first. If two vehicles reach the intersection at the same time, the driver on the left yields to the driver on the right.

Various traffic control devices are used in road construction and maintenance work areas to direct drivers and pedestrians safely through the work site and to provide for the safety of highway workers. Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger and/or police officer.

Police drones can be used for many different purposes - m.in. for monitor various situations from the air or to provide operational support. One of the most common areas of use of such devices is traffic control. But that's not all - a police drone is also an increasingly common sight when securing mass events or searching for missing persons. In addition, the police drone allows surveillance of hard-to-reach areas, such as forest and mountainous areas or dense urban areas, without involving a large number of officers. The police drone is particularly useful at events such as concerts, demonstrations or sports competitions, enabling rapid detection of threats and coordination from the air.

White lane lines separate lanes of traffic moving in the same direction. Single white lines may also mark the right edge of the pavement.

If your car stalls on the tracks don't hesitate. Get yourself and your passengers out and away from the car immediately. If a collision is imminent, the safest direction is toward the train but stay off the tracks. That way you will be least likely to be hit by your vehicle or any debris from the collision.

Always approach highway-railroad crossings at a reasonable speed — and be prepared to stop if you have to. Be especially alert when you are following buses or trucks which may have to stop at highway-railroad crossings even if any gates are up and the warning lights are not flashing.

A solid white line marks the edge of the pavement on most roads. Stop lines, crosswalks and parking spaces are also marked by white lines. Symbols such as arrows are in white also. A single yellow line marks the left edge of all divided or one-way roadways. Curbs are often marked yellow in no-parking zones near fire hydrants or intersections.

Stop signs are always octagonal (8 sided). A stop sign means that you must bring your vehicle to a complete halt at the marked stop line.

Some highways have reversible traffic lanes to help handle rush-hour traffic. The direction of traffic is normally reversed at set times each day. These pavement markings are used along with special lane signals and other signs and symbols.

Police drone is an increasingly important piece of equipment for Polish police. Already one in ten Poles has encountered fines for offenses recorded with a drone or has heard of such a situation, and 70% of people believe that a police drone is an effective way to improve road safety (for more information, see our report "What Poles think about the use of drones?"). The devices are used in a variety of ways, depending on the operational needs of the location - but the most common use of the devices is specifically focused on traffic. In recent months, a police drone is also a relatively common sight on the Polish-Ukrainian and Polish-Belarusian borders, where equipment of this kind supports both border guards and the military, as well as the police. There are many indications that the police drone is a solution that will stay with us for a long time - mainly because of the numerous possible applications of such devices. In addition to recording traffic violations, the police drone can also serve as a supporting rescue operations and assisting in the prosecution of criminals, which makes it an extremely useful tool for various services.

GREEN GUIDE SIGNS Green and white signs give information about directions and distances. Guide signs on expressways show you which lanes to use to get where you want to go. Routes that run generally East-West have even numbers and those running North-South have odd numbers.
