Read the following passage about driving laws around the world, and then tick the correct answers: true (T), or false (F). • Keep your car clean and shiny if you are in Russia, because driving a dirty car can get you fined up to 2,000 rubles (about $57). • In Costa Rica, you can drink beer while driving if you don’t get drunk. You can drink beer with one hand and drive your car through the winding roads of Costa Rica. • Make sure that you have enough fuel in your car tank when you drive in the famous high street in Germany - Autobahn. If you run out of gas, you will break the law. • Drivers in France are required to carry a breathalyzer kit in their cars. Originally, drivers who didn’t have one were required to pay a fine of €11, but this has been delayed. • If you are not drunk, don’t get in a car with a drunk driver. In Japan, sober passengers with a drunk driver can be punished under the law. • In Cyprus, eating or drinking (even water) while driving is illegal. Eating a quick snack or taking a sip of soda will make you pay an €85 fine. • Luxembourg is serious about security, and cars are not allowed to drive if they are not equipped with working windshield wipers. • In Manila, the Philippines, you cannot drive your car on Monday if the number plate ends with 1 or 2.
