General provisions. The operation of vehicles that are vehicles of increased danger requires the implementation of the basic rules for preparing vehicles for work and traffic safety. Among the numerous factors affecting the safety and trouble-free operation of the car, the main ones should be highlighted: the technical condition of the car; the physical and mental state of the driver; a clear knowledge of the Rules of the Road, their unconditional implementation, as well as: the category and condition of the road; traffic intensity; driver's ability to evaluate the continuously changing traffic situation and make the right decisions in choosing the speed and direction of movement, skillfully coordinate their actions with the actions of other road users. The experience of the driver and the ability to properly use the technical capabilities of the car also affect traffic safety.

The designs of modern cars mostly meet the requirements safe operation. The preparation of vehicles of various types and purposes for operation and their maintenance in a normal technical condition are regulated. Particular attention is paid to the technical condition of systems that directly affect traffic safety. These include: the state of the working and parking brake systems; steering; external lighting devices; windshield wipers and washers; tires; engine and other elements provided for by the design of the car. It is forbidden to make changes to the design of the car that impair the safety of its operation.

The technical condition of the car. Brake system must act effectively without causing the vehicle to skid. The braking distance during road tests of the working brake system on a dry paved highway with a given initial speed should not exceed the established norms. The tightness of the hydraulic and pneumatic drives must not be broken. There must be no air in the hydraulic drive of the brakes. If free play pedal has increased or the control lamp of the signaling device has lit up, it is necessary to find out and eliminate the cause of the malfunction of the brakes and bleed the brake hydraulic drive, removing air from it. It is necessary to timely adjust and, if necessary, replace faulty parts or assemblies of the brake drive mechanism.

If the car is equipped with a pneumatic brake drive, then the car must not be started if the pressure in the pneumatic system of the drive is below 0.5 MPa, and it is necessary to prevent the pressure from dropping when driving below this value. At a pressure below 0.5 MPa, the control lamp on the instrument panel lights up. On long descents, the engine must not be turned off so as not to use up the entire supply of air from the pneumatic system cylinders. On vehicles with hydraulic brakes, the vacuum brake booster will not work when the engine is off.

Condensate from air cylinders is drained only when there is air pressure in the system. At high air humidity and in winter, condensate must be drained daily to prevent it from freezing in devices and pipelines. After draining, it is recommended to fill the system with air and stop the engine.

The trailer is coupled and uncoupled from the car only on a hard-surfaced horizontal platform. If the trailer is equipped with a combined brake drive, then only a two-wire system must be used when hitching.

The parking brake system must ensure a stationary standing: vehicles with a full load on a slope up to 16% inclusive; trucks and road trains in running order on a slope of 31% inclusive; cars and buses in running order on a slope up to 23% inclusive.

Steering must be in good technical condition. The total play in the steering must not exceed the allowable values. The rules of the road established that for cars and trucks created on their basis, the total play, measured by the angle of rotation of the steering wheel, should not be more than 10 °; for buses - 20°; for trucks - 25°.

For trucks with power steering, the steering wheel play with the engine running at low speeds should also not exceed 25 °, for a new car - no more than 15 °. Systematically check the play in the steering rod joints and drive parts. If there is a backlash, it is eliminated by adjustment, in necessary cases replace worn parts.

For vehicles equipped with power steering, prolonged towing of the vehicle with the engine off is prohibited. Do not turn off the engine on long descents and when coasting, as the hydraulic pump stops working and driving becomes difficult. You should not move for a long time with inverted in extreme position wheels, for example, when leaving the track, as the hydraulic pump of the hydraulic system may fail due to overheating of the oil. Short-term movement at low speed with a faulty hydraulic booster to the garage is allowed. The power steering system is factory filled with multigrade oil brand Div during the operation of its replacement is not required. During the operation of the car, the oil level in the hydraulic booster is monitored and topped up to the set level.

Tires. The condition of the tires affects their grip on the road. Passenger car tires must have a residual tread depth of at least 1.6 mm, trucks and their trailers - at least 1.0 mm, buses - at least 2.0 mm. Vehicles must be fitted with tires recommended by the manufacturer, according to type, size and permissible load. It is not allowed to install tires of different dimensions, different types (diagonal and radial) and with different tread patterns on one axle, as the vehicle's handling deteriorates. Tire pressure should be maintained in accordance with specifications on their operation and check when the tires are completely cool. Reducing tire pressure by 25% reduces their service life by 2 times. In addition, the condition of the tire tread and air pressure in them affect the stability and handling of the car. In cars high cross equipped with tires with a small number of cord layers and a system of centralized pressure change in them, it is allowed to reduce the air pressure only to improve the patency when overcoming difficult sections of the track. Reducing the pressure in tires below 0.05 MPa can lead to their failure.

External lighting fixtures. Their number, type and location must comply with the requirements of the vehicle design. They must be in good condition and adjusted so as not to interfere with other road users, and signal the start of movement and a change in direction of movement, stopping or maneuvering. It is not allowed to install and use external electric lighting devices that are not permitted by the Rules of the Road.

Windshield wipers and washers must be in good condition.

Engine. In the exhaust gases, there should not be an emission of toxic substances (CO, CH, NO x) more than prescribed by law. Before work, the car engine should be warmed up until it runs steadily for idling and do not start driving if the warning lights with red filters are on on the instrument panel. It is forbidden to warm up the engine in an enclosed area with poor ventilation in order to avoid poisoning by exhaust gases. There should be no violations of the tightness of the power supply system.
