If you’re among the millions of Americans packing their vocation bags for summer trips, don’t forget, however, that as soon as you step off the plane, you’re expected to follow that country’s laws. We took a look at one of the top countries Americans are most likely to visit and what might happen if you got caught.

Mexico

Smoking marijuana(大麻): If police find you smoking a cigarette which contains marijuana, they will most likely detain you overnight and you will get a fine.

Carrying a firearm: You might be able to walk around with a gun in Texas, but that isn’t so in Mexico, so leave your gun behind. If you wish to go hunting in Mexico, you can apply for a gun permit but are expected to be charged $5,000. If you are caught bringing a firearm, Mexican policeman may take away your car and arrest you. An arrested American may spend months in prison while his or her case is being looked into.

Driving 70 mph on the highway: Speed limits are on the lower side. Depending on what type of highway you’re driving on, you shouldn’t go faster than 60mph. The police enforce (执行) the speed limit, but most local police don’t have radars(无线电探测器). The maximum fine for speeding is about $40. To scare (吓得某人做……) tourists into paying the fine “on the spot”, sometimes police will threaten to keep your driver’s license (驾照). This is illegal.
