Why: Marijuana is a substance that impairs the central nervous system, leading to slower physical and mental responses. It never improves reaction time; instead, it makes it much harder to respond quickly to road hazards.
Why: Marijuana is the most frequently detected drug after alcohol in drivers involved in traffic accidents. It significantly impairs the cognitive and motor skills required to operate a vehicle safely.
Why: According to Chapter 5 of the driver's manual, a flashing yellow light serves as a warning of potential hazards. You are required to reduce your speed and remain alert as you move through the intersection.
Why: Large flashing or sequencing arrow panels are used in work zones to direct traffic into specific lanes during both day and night. According to Chapter 5, these devices warn drivers that a portion of the road ahead is closed and guide them safely around the hazard.
Why: According to the driver's manual, you must stay on the right side of the road unless specific exceptions apply. Driving on the left is strictly prohibited when there are multiple lanes, near intersections, or when pavement markings like solid lines forbid it.
