Subway Rules People Systems Eslpod Passengers Follow Clean

Many large "metropolitan" (city) areas have subways, but "commuters" (people who travel to and from work) have to agree to follow rules in order to ride the subways. Many of the rules are intended to keep the subway system clean and free of "rodents" (rats, mice, and other small mammals that are attracted by garbage) and insects. For example, subways "prohibit" (forbid; do not allow) smoking to "maintain" (keep at its current level) "air quality" (how clean the air is). Most subway systems also prohibit eating and drinking. Passengers may carry food in "closed" (unopened) containers, but they may not "consume" (eat or drink) it while they are in the subway system.

Other rules are "enforced" (with people being made to follow the rules) for passengers' safety. For example, subway systems prohibit guns, knives, and other weapons. Subways systems "reserve the right" (are allowed) to ask people to leave if they are "inebriated" (drunk; under the influence of alcohol) or obviously under the influence of drugs. People are asked to report "unattended items" (objects that do not appear to belong to a passenger) so that employees can determine whether they are "explosive devices" (bombs or similar objects that can catch on fire and cause damage and injuries or death).

"Still other" (Additional) rules are designed to "promote" (encourage) the passengers' comfort and enjoyment. People are asked or required to give up their seats for the "elderly" (older people, usually more than

65 years old), the "disabled" (people who do not have full use of part of their body), and pregnant women. Radios and other musical devices are prohibited unless the passenger is using "headphones" (small pieces that enter the ears and are attached to the source of music with wires, so that only one person hears the music).
