First of all, you need to pay attention to the spare tire, which must be present in every car. Sometimes some drivers, when installing LPG equipment that uses small toroidal cylinders, throw away the spare tire. And as a result, the car will be left on the road until a service vehicle arrives...
A jack should also be available. If earlier reliable but extremely heavy hydraulic jacks were widely used for lifting cars, now it's better to take lightweight and practical screw jacks.
Special attention should also be paid to the pump. Using hand pumps that require a lot of physical effort is not always convenient. For inflating tires, it's better to use either foot pumps or electric portable pumps. The latter are valuable because they can work from the standard cigarette lighter. The power of electric pumps is high enough to inflate all the car's tires quickly.
A tow rope is also considered an essential accessory for any modern car. If a serious breakdown occurs (for example, the engine 'knocks'), the broken car can be easily towed to a garage. Using seat belts, even if they are extra strong, will no longer be necessary.
A canister and a funnel are also considered essential attributes of any car – if you run out of fuel, you won't have to use a 'siphon' in the form of a rubber hose.
Special attention should also be paid to the fire extinguisher. It is not worth buying and installing it only to pass the technical inspection. A good fire extinguisher, if a fire occurs, will be useful in many cases. For example, if inside the cabin, due to a short circuit, the electrical wiring starts to smolder, when the doors are opened it will certainly flare up. And the cabin will burn out within a few minutes for sure. But the situation can be controlled if you have a small but properly working modern powder fire extinguisher at hand.
And be sure to keep a charged phone at hand, with the numbers of emergency services or a taxi saved in the address book. Even if your car is in perfect order, there may always be a need for outside help. For example, one of the transport companies offers its clients the service sober driver in Moscow, which may be needed if you are unable to drive yourself. And now clients of the company who are delayed at a business meeting or a friendly party do not have to worry about their car – it will be delivered by professionals in perfect condition!
