2) you should slow down in villages .
you mustn't consult a map when driving .
you must wear your seatbelt in the front and back .
you mustn't drive at night when you feel tired.
you mustn't take your car if you've had a drink .
3) can't - mustn't - can- must .
4) - you'd better go home and take rest .
- you'd better stay at home . :)
