Traffic accident: what to do? Advice from the lawyer

traffic accident

When there is a crash in a traffic accident and their beloved car is over, many do not know what to do. However, correct behavior after a traffic accident is extremely important for successful claims settlement.

We help you avoid mistakes with simple behavioral tips. Then you can effectively enforce your claims and get your rights.

9 golden rules of conduct in the event of a traffic accident

  1. Secure the accident site: Switch on the hazard warning lights after a traffic accident. Put on the safety vest. Set up the warning triangle approx. 50 to 100 meters away from the scene of the accident.
  2. Take photos of the accident : Take photos of the scene of the accident with your mobile phone or camera after a traffic accident. These pictures will be beneficial for you whe you’ll need to visit personal injury lawyer. Also take photos of the damage caused to the vehicles. Only then do you move the cars! Only then can the exact location of the vehicles involved in the accident at the time of the accident be proven retrospectively. Difficulties in providing evidence in later disputes about the course of the accident can be effectively avoided.
  3. Note the license plate number and name of the other party involved in the accident: You should make a note of the license plate number and the name of the other party involved in the accident. With the license plate, the insurer of the opposing vehicle can easily be found out. He has to pay for the damage you suffered. At the central call of the car insurer, the corresponding motor vehicle liability insurer can be found out via the license plate number.
  4. Write down witnesses: Make a note of the names, addresses, and telephone numbers of witnesses. As a neutral observer of the traffic accident, they can be the decisive factor in your direction in disputes with the opposing insurance company.
  5. Call the police: you should always call the police after a traffic accident. Only in this way will the accident be documented by the police on site. Do not trust the statement of the other party involved in the accident that the matter can be settled “in secret”. Experience has shown that the goodwill of the other party involved in the accident usually ends with one’s own wallet.
  6. No admission of guilt at the scene of the accident: If you are (partially) at fault in a traffic accident, never give an oral or even written admission of guilt to the other party or the police. Such a declaration can nullify your claims.
  7. Have an appraisal made: Have a cost estimate made for vehicle damage of less than 800 euros. In the case of higher damage, an expert opinion should be drawn up by a vehicle expert selected and commissioned by you. The cost of a cost estimate or an expert opinion must be paid by the opposing insurance company if the other party to the accident was responsible for the traffic accident. Do not allow the assessment by an expert offered by the opposing insurance company! This expert works primarily for the opposing insurance company. The opposing insurance company, however, has a vehement interest in the least possible damage!
  8. Consult a doctor: If you have been injured, do not hesitate to consult a doctor immediately after the traffic accident. Only in this way can personal injury be documented and a claim for compensation for pain and suffering later successfully enforced. Keep all receipts for medical bills, prescription costs, travel expenses, etc. in a safe place.
  9. Contact a lawyer: Find a traffic lawyer quickly and get advice. Then your claims will actually be enforced and you will get your money. If the other party in the accident was at fault, the legal fees are paid in full by the opposing insurance company. Otherwise, the lawyer receives his fee through an existing traffic legal protection insurance. If you do not yet have traffic legal protection insurance, you should immediately conclude a corresponding legal protection insurance contract (without excess) in order to protect yourself effectively in the future. Such insurance often only costs a few euros a month.

Concrete is a composite material, comprising a matrix of combination and a binder, which holds the matrix collectively. Many forms of concrete are available, decided by the formulations of binders and the forms of the mixture used to suit the application of the material. These variables determine energy and density, in addition to the chemical and thermal resistance of the finished product.

Any mixture of these elements and others may result in a combination that is simply too harsh, i.e., which does not circulate or unfold out smoothly, is difficult to get into the formwork, and which is difficult to floor end.

Water runs by way of the voids in the pavement to the soil underneath. Air entrainment admixtures are often used in freeze-thaw climates to reduce the possibility of frost injury. Pervious concrete also permits rainwater to filter by way of roads and parking lots, to recharge aquifers, as an alternative to contributing to runoff and flooding. Asphalt mixtures have been utilized in pavement building for explanation at the beginning of the twentieth century. It consists of mineral aggregate certain along with asphalt, laid in layers, and compacted.

Workability is the power of fresh concrete combined to fill the form/mold correctly with the desired work and without decreasing the concrete’s quality. Workability is dependent upon water content, mixture, cementitious content material, and age and can be modified by adding chemical admixtures, like superplasticizers. Raising the water content or including chemical admixtures increases concrete workability. Excessive water results in increased bleeding or segregation of aggregates, with the resulting concrete having reduced high quality. The use of a combination blend with an undesirable gradation can end result in a really harsh combined design with a very low droop, which can’t readily be made more workable by the addition of reasonable amounts of water.

The configuration of the entrance and rear molds dictates the minimum and most paving widths and the quantity of total width variation.

Superplasticizers (also called high-range water-reducers) are a class of plasticizers that have fewer deleterious results and can be used to extend workability more than is practical with conventional plasticizers.

Concrete is a comparatively brittle material that is sturdy under compression but less in rigidity. Plain, unreinforced concrete is unsuitable for so much of buildings as it’s comparatively poor at withstanding stresses induced by vibrations, wind loading, and so forth. Hence, to extend its total power, metal rods, wires, mesh or cables could be embedded in concrete earlier than it’s set. This reinforcement, typically often recognized as rebar, resists tensile forces. Very low-strength—14 MPa or less—concrete may be used when the concrete must be lightweight. Lightweight concrete is usually achieved by including air, foams, or lightweight aggregates, with the aspect effect that the strength is reduced.
