Why: Marijuana impairs your driving abilities, including your focus, night vision, and perception of speed. According to the manual, it "slows your ability to process information," meaning it causes slower, not faster, reaction times. Therefore, a faster reaction time is NOT a likely effect.
Why: Marijuana is the most frequently detected drug other than alcohol in the systems of drivers involved in crashes. It significantly impairs the coordination and reaction time required for safe driving.
Why: According to the manual, you must generally drive on the right half of the roadway. If you are driving slower than the rest of the traffic, you are not allowed to use the leftmost lane, as it blocks faster-moving vehicles.
Why: When a school bus stops with flashing red lights on a road with fewer than four lanes, traffic from both directions must stop. You must stop at least 10 feet away to ensure children can cross safely.
Why: In Ohio, you are allowed to turn right at a red traffic signal after coming to a complete stop. You must yield to all crossing traffic and pedestrians before proceeding.
