Road rules are essential regulations that govern how vehicles and pedestrians interact on the road. They are designed to ensure safety, promote orderly traffic flow, and reduce accidents. Common rules include obeying speed limits, yielding to pedestrians, and using turn signals when changing lanes. Understanding and following road rules is crucial for all road users, including drivers, cyclists, and pedestrians. These rules vary by region but generally include guidelines for safe driving practices, such as not driving under the influence of alcohol or drugs and maintaining a safe following distance from other vehicles.
