Summarize this article:

You are not likely to be pulled over by the police, but there are laws regarding operating a motor vehicle in a public parking lot, just as there are on the highway. Here are some things to watch for.  Posted speed limits. Many large parking lots do have posted speed limits or road markings, which are for the safety of pedestrians and other road users, please abide by them.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/c0\/Use-Parking-Lot-Etiquette-Step-8Bullet1.jpg\/v4-460px-Use-Parking-Lot-Etiquette-Step-8Bullet1.jpg","bigUrl":"\/images\/thumb\/c\/c0\/Use-Parking-Lot-Etiquette-Step-8Bullet1.jpg\/aid370867-v4-728px-Use-Parking-Lot-Etiquette-Step-8Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  One-way signs and markings. In parking lots with diagonal spaces, individual lanes may be one way, most often marked with a directional arrow painted on the pavement at the end of each lane. Even if the lane is not marked, you may be safe to assume the lane is one way if the diagonal spaces are oriented in the same direction on both sides.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/b\/b6\/Use-Parking-Lot-Etiquette-Step-8Bullet2.jpg\/v4-460px-Use-Parking-Lot-Etiquette-Step-8Bullet2.jpg","bigUrl":"\/images\/thumb\/b\/b6\/Use-Parking-Lot-Etiquette-Step-8Bullet2.jpg\/aid370867-v4-728px-Use-Parking-Lot-Etiquette-Step-8Bullet2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Stop and Yield signs.  These serve the same purpose in parking lots they serve on city streets, allowing the right-of-way to a vehicle driving in a certain lane or direction, and should be obeyed.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/6\/63\/Use-Parking-Lot-Etiquette-Step-8Bullet4.jpg\/v4-460px-Use-Parking-Lot-Etiquette-Step-8Bullet4.jpg","bigUrl":"\/images\/thumb\/6\/63\/Use-Parking-Lot-Etiquette-Step-8Bullet4.jpg\/aid370867-v4-728px-Use-Parking-Lot-Etiquette-Step-8Bullet4.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Disabled and elderly spaces. Disabled parking spaces are generally clearly marked with signs and special striping, and are wider than regular spaces to accommodate wheelchairs. They are located near disabled ramps, usually very close to the entrance of the shop. If you do not require the use of these spaces, and do not have a permit, park somewhere else as parking there would be an inconvenience to them, and it is illegal in many places.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7c\/Use-Parking-Lot-Etiquette-Step-8Bullet3.jpg\/v4-460px-Use-Parking-Lot-Etiquette-Step-8Bullet3.jpg","bigUrl":"\/images\/thumb\/7\/7c\/Use-Parking-Lot-Etiquette-Step-8Bullet3.jpg\/aid370867-v4-728px-Use-Parking-Lot-Etiquette-Step-8Bullet3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Pedestrian crosswalks. These are common near the main entrances and exits of most large businesses, for the safety of pedestrians returning to their cars. They are usually marked with diagonal white or yellow stripes, and often also are marked with a pedestrian crossing or stop sign.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/6\/60\/Use-Parking-Lot-Etiquette-Step-8Bullet5.jpg\/v4-460px-Use-Parking-Lot-Etiquette-Step-8Bullet5.jpg","bigUrl":"\/images\/thumb\/6\/60\/Use-Parking-Lot-Etiquette-Step-8Bullet5.jpg\/aid370867-v4-728px-Use-Parking-Lot-Etiquette-Step-8Bullet5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Indicators/Turn signals. Using indicators gives other road users an idea of what your intentions are, use them in a timely manner to show what you are doing.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/d\/d5\/Use-Parking-Lot-Etiquette-Step-8Bullet6.jpg\/v4-460px-Use-Parking-Lot-Etiquette-Step-8Bullet6.jpg","bigUrl":"\/images\/thumb\/d\/d5\/Use-Parking-Lot-Etiquette-Step-8Bullet6.jpg\/aid370867-v4-728px-Use-Parking-Lot-Etiquette-Step-8Bullet6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}
