Why: Marijuana slows down your brain and body, making it harder to react to hazards. It never improves your reaction time; it only makes it worse.
Why: Marijuana is the most frequently detected drug (other than alcohol) in the systems of drivers involved in collisions. It significantly impairs judgment, motor coordination, and reaction time.
Why: When a school bus flashes red lights on a two-lane road, you must stop completely. This applies to traffic in both directions to ensure student safety.
Why: When two vehicles reach an intersection at the same time, the driver on the left must yield to the driver on the right. This rule helps maintain order and prevent collisions at four-way stops or uncontrolled intersections.
Why: You are allowed to pass other vehicles when the line next to your lane is dashed. This indicates that lane changes and passing are permitted when it is safe to do so.
