Documents required for renting a car in the country - a valid international driver's license.

The driver must be over 21 years old.

Traffic is right-hand. 

It is absolutely necessary to buckle up in the car, and for everyone who is there.

The speed of movement is limited:

– in a locality-40-60 km / h;

– outside the locality-90-100 km / h;

– on the Highway-110 km/h.

The presence of alcohol in the blood is not allowed at all. The fine is 600 dollar and revocation of the driver's license for 1 year.

Since there are a lot of cars in the country, the situation with congestion of highways in Brazil is solved in a very original way. During the period from 7:00 to 10:00 and from 17:00 to 20:00, only cars can travel on the roads whose sign ends with the allowed number can use the roads.

1. If you want to withdraw a large amount of money from a Brazilian ATM, you should always do so before 10 pm. Not only is it safer to withdraw money during daylight hours, but after 10 pm the withdrawal limit drops to 500 reais.

2. The Brazilian bus system is surprisingly good if you know what you're doing. While it can be difficult to find bus schedules and price information online (especially in English), it's best to go to the bus station in person and ask at the ticket office. The metro lines in Rio de Janeiro and São Paulo are small, but ideal for getting around the main attractions without spending too much money. Taxis are also quite cheap in the northeast of Brazil. In national parks or on coastal routes, you can even rent a cheap car so that you don't have to depend on expensive travel companies.

3. In Brazil, the hand symbol "OK" is the equivalent of giving someone the middle finger. This is considered very rude and even offensive to some people. 

4. Favelas are crowded, very poor neighborhoods usually built on the hillsides of Rio de Janeiro. All favelas are controlled by gangs or the mafia, where people sell drugs and openly carry machine guns. 

Although a favela tour is absolutely safe, and favelas in general can be relatively safe during daylight hours, it is still best to avoid them if you are not with a group.

5. In general, don't walk the streets after dark (which is around 6pm all year round). As an international tourist, if you need to go somewhere after dark, use Uber or a taxi, or take the subway if you need to walk less than a block to/from the station to your destination. 

Beware of pickpockets (or thieves snatching your phone out of your hand), especially in places like Copacabana, markets, and other touristy places. If you're riding in a taxi or uber with the window down, be aware that passersby, bikers, or people selling on the street when the cars are stopped sometimes snatch phones right out of your hands in the car.

6. There are two types of plugs used in Brazil: type C and type N. The type C plug has two round pins, and it is also widely used in many European countries. The N type plug has two round pins and a grounding pin.

7. The main working hours of most shops and businesses are Monday through Friday from 9:00 to 18:00 and on Saturday from 9:00 to noon, with an extended lunch break from about noon to 2:00. Shops in shopping centers are open until late at night on Saturday. Banks open at 10 am and are open all day, but usually stop changing money at 2 pm or 3 pm; with the exception of banks at major airports, they are closed on weekends and holidays. Museums and monuments more or less follow the opening hours, but many are closed on Mondays.

8. In the subway in the main cities, the cars are reserved for women only, but this rule applies only during peak hours from 6 to 9 am and from 5 to 8 pm from Monday to Friday.

If a man enters one of these cars, he faces a fine of up to 1,000 reais, which is equivalent to $320. Outside of rush hours, both women and men are allowed to use these cars.

Safety in this subway does not tolerate any excuses, especially since there are warnings in the cars that are written in Portuguese and English and are intended only for women.

9. When you arrive at the airport in Brazil, book a taxi through one of the agencies or call uber, rather than using unofficial taxi services. Although it costs more, you will not be charged extra when you arrive at your destination.
