Why: Marijuana impairs your ability to drive safely by slowing down your body's responses and cognitive functions. It does not make you react faster; instead, it significantly delays your decision-making and physical movements.
Why: Marijuana is the most frequently detected drug other than alcohol in the systems of drivers involved in crashes. It significantly impairs judgment, motor coordination, and reaction time.
Why: At an uncontrolled intersection where no signs or signals exist, the vehicle on the right has the right-of-way. This rule helps maintain order and prevents collisions when drivers arrive simultaneously.
Why: According to the South Carolina driver's manual, you must park your vehicle within 18 inches of the curb. This ensures your car doesn't stick out into the lane of travel and obstruct other drivers.
Why: Parking is strictly prohibited in specific zones to ensure public safety and allow emergency vehicles unobstructed access. These restricted areas include spaces near fire hydrants, pedestrian crosswalks, and railroad crossings.
